Air Masses
An air mass is a large volume of air that takes on consistent temperature and humidity characteristics based on the region over which it travels. There are four main types of air masses: maritime tropical (warm and humid), continental tropical (warm and dry), maritime polar (cold and humid), and continental polar (cold and dry). Weather patterns change as different air masses are pushed around the Earth by forces like the jet stream, which generally moves air masses from west to east across the United States.
Air masses (summary)
This document discusses air masses, which are large bodies of air that share similar temperature and moisture characteristics. Air masses originate over source regions and are classified based on the latitude and surface type of the source region. The weather experienced in an area depends on the characteristics of the prevailing air mass. The main air masses that affect North America are continental and maritime polar and tropical air masses.
Air mass
An air mass is a large body of air with similar temperature and moisture properties that can cover hundreds of thousands of square miles. Air masses originate over land or water source regions and take on the characteristics of the surface below over time. There are four main types of air masses defined by their source region in tropical or polar latitudes and whether that region is over land or water. When polar air meets warmer air over the United States, it causes the formation of the polar jet stream, a narrow belt of strong winds near the top of the troposphere that influences weather patterns and temperatures in the US.
Chapter 16 2 Air Masses, Fronts And Weather Maps Andie
An air mass is a large volume of air that has uniform temperature and humidity characteristics based on the region it forms over. There are four main types of air masses: maritime tropical, continental tropical, maritime polar, and continental polar. Weather fronts occur when different air masses meet, with warm fronts and cold fronts creating different weather conditions based on whether the warmer or colder air is overriding the other. Weather maps use symbols like isotherms, isobars, and frontal boundaries to depict these air mass interactions and the resulting weather patterns.
18. air masses and fronts notes
Air masses take on characteristics of the regions where they form and remain stationary. They are classified by temperature and moisture content as either continental, maritime, tropical, or polar. Fronts form boundaries between differing air masses and can cause precipitation. Cold fronts push warm air out of the way while warm fronts lift warm air over colder air. Stationary fronts move slowly and occluded fronts occur when a cold mass overtakes a warm one. Cyclones are low pressure storm systems that rotate counter-clockwise along storm tracks, while anticyclones bring dry weather with sinking air flowing outward clockwise from high pressure centers.
Fronts
Fronts are boundaries between two air masses of differing characteristics. There are four main types of fronts: cold fronts, warm fronts, occluded fronts, and stationary fronts. Cold fronts are steep boundaries where cold air overrides warm air, bringing precipitation. Warm fronts are more gradual, with light, continuous precipitation as warm air rises over cold air. Occluded fronts occur when a cold front catches up to a warm front. Stationary fronts have little or no movement as the air masses are parallel.
Air masses and fronts
- Air masses are large bodies of air with uniform temperature and moisture characteristics that form over source regions. The main types are continental polar (CP), maritime polar (MP), continental tropical (CT), and maritime tropical (MT).
- Fronts occur at boundaries between converging air masses. The main types are cold fronts, warm fronts, stationary fronts, and occluded fronts. Cold fronts bring strong winds and thunderstorms while warm fronts bring gentle rain.
- Frontogenesis is the formation of fronts while frontolysis is the dissipation of fronts. Mid-latitude cyclones form due to frontogenesis between air masses.
Air masses and fronts 2013
An air mass is a large body of air with similar temperature, pressure, and humidity levels throughout. There are four main types of air masses: maritime, continental, polar, and tropical. Air masses get their properties from spending prolonged periods over certain areas, such as oceans or polar regions. When two different air masses meet, fronts are formed. The three main types of fronts are cold fronts, warm fronts, and stationary fronts.
Air masses And FRonts
This document discusses air masses and fronts. It defines air masses as large bodies of air that extend thousands of kilometers and have uniform temperature and humidity. Air masses form over source regions and are classified as either tropical or polar, and continental or maritime. Fronts occur at the boundary between differing air masses and can be cold, warm, stationary or occluded fronts. Each front type brings characteristic weather conditions from rain to thunderstorms as the warmer air is displaced.
Weather lesson
This document provides an overview of key weather concepts including:
1) It outlines the objectives of the weather lesson which are to learn about weather instruments, high and low pressures, winds, air masses, fronts, reading station models, and severe weather and clouds.
2) It describes different weather instruments and how barometric pressure is measured in millibars using isobars on weather maps.
3) It explains high and low pressure systems, including how they spin differently in each hemisphere due to the Coriolis effect.
Weather and climate
The document discusses the differences between weather and climate. It states that weather is the short-term atmospheric conditions of an area, ranging from minutes to weeks. Climate is the average weather conditions in an area over a longer period of 30-40 years. The main difference is that weather describes the atmosphere over a short time, while climate is based on long-term weather trends. It also discusses paleoclimate, which is the study of past climates prior to instrumental records through proxy data sources like tree rings, ice cores, and sediments.
What makes up weather ( whole presentation )
The document summarizes the layers of the atmosphere and factors that influence weather. It discusses the five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - and characteristics of each. Weather variables like temperature, wind, moisture, and precipitation are identified. The angle and intensity of solar insolation is explained, noting it is greatest at the equator and lowest at the poles. Air pressure variations result from uneven heating and cooling, with low pressure where air is warm and high pressure where air is cool. Differences in pressure cause surface winds and convection cells in the atmosphere.
Water in the atmosphere and Weather Pattern
Fogged up windows and bad hair days are caused by humidity in the air. Water vapor condenses as clouds, dew, frost or fog depending on temperature. Clouds form through various processes and can be classified into categories like stratus, cumulus or cirrus clouds based on their shape and altitude. Air masses and fronts influence weather patterns as different air masses collide and interact.
Fronts and Air Masses
Fronts occur where two different air masses meet but do not mix. There are four main types of fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts. Cold fronts move quickly and bring cooler, drier air behind them, often causing rain and storms. Warm fronts move more slowly and bring cloudy skies and light rain before warmer, more humid air moves in. Stationary fronts occur when neither air mass can push the other, resulting in prolonged wet weather. Occluded fronts form when a warm air mass gets trapped between two cold fronts.
Atmosphere, weather and climate
This document summarizes key concepts about Earth's atmosphere and weather. It describes the four main layers of the atmosphere, how temperature and pressure vary with altitude. It also explains atmospheric phenomena like humidity, dew point, condensation, cloud types, global wind patterns, air masses, fronts, and severe weather events like thunderstorms, tornadoes and hurricanes.

Weather and climate
The document discusses the differences between weather and climate. Weather describes current atmospheric conditions in a place, while climate refers to conditions over a long period of time. It then describes the structure of the atmosphere, including the troposphere, stratosphere, mesosphere, and thermosphere. The atmosphere contains gases like nitrogen, oxygen, and carbon dioxide that make life possible. Temperature on Earth varies depending on factors like latitude, altitude, and distance from bodies of water.
Weather patterns
Fronts are boundary surfaces that separate air masses of different densities. Warm fronts occur when warmer air overrides cooler air, causing the warmer air to lift up along the wedge of cold air. This lifting causes clouds and precipitation to form ahead of the surface position of the warm front. As the warm front passes, air temperatures gradually rise and skies typically clear.
Air Masses
There are several major air masses that influence weather patterns:
1) Continental Arctic (cA) air masses are very cold and dry, originating north of the Arctic Circle.
2) Continental polar (cP) air masses are cold and dry, originating in northern Canada and influencing northern US weather.
3) Maritime polar (mP) air masses are cool and moist, originating over the North Atlantic and Pacific and influencing the Pacific Northwest and Northeast.
4) Maritime tropical (mT) air masses are warm and moist, originating in the Gulf of Mexico and influencing the eastern US.

Upper atmosphere air movements
The document discusses the cell model of global air circulation. It explains that air rises near the equator and descends around 30 degrees north and south latitude, creating zones of high and low pressure. Variations in upper-level jet streams and Rossby waves influence surface weather patterns, such as bringing low pressure systems to the UK. The lesson aims to explain how upper-atmosphere movements cause changes in surface air pressure globally.
Airmass
An air mass is a large body of air with similar temperature and humidity characteristics that forms in stable source regions such as the subtropics or polar regions. There are five main air masses that affect Europe: tropical maritime (mild and moist), tropical continental (warm and dry), polar maritime (cool and moist), polar continental (cold and dry), and arctic maritime (cold and moist). Each air mass originates over a different source region and brings distinct weather conditions depending on its temperature and moisture content.

The Earth- A Very Basic Intro
The document provides a basic introduction to the Earth by discussing three key facts:
1) The Earth is the third planet from the Sun and is located in the solar system within the Milky Way galaxy.
2) Unlike a simple "rock," the Earth has an atmosphere, is over 70% covered in water, and has a molten interior, allowing life to exist.
3) Two factors that enable life on Earth are its rotation on an axis, which causes day/night cycles and seasons, and its orbit around the Sun, regulating temperatures.
Rock Formation Q & A
The document provides information about rock formation and classification. It defines igneous, sedimentary and metamorphic rocks. Igneous rocks form from cooling magma, either below the surface (intrusive) or above (extrusive). Sedimentary rocks form through compaction and cementation of sediments. Metamorphic rocks form from changes to existing rocks through heat, pressure and fluids. Rocks are classified based on texture, composition and formation processes. The rock cycle illustrates how rocks continuously change between the three main types through various natural processes.

Earth layers
The Earth is divided into four main layers - the crust, mantle, outer core, and inner core. The crust is the outermost layer and makes up only 1% of the Earth. Below the crust lies the mantle, which is the largest layer and consists of the upper and lower mantle. At the center are the inner and outer core, with the outer core being liquid iron that generates the Earth's magnetic field and the inner core being solid iron.
The Layer of the Earth song and ppt
The Earth is composed of three main layers - the crust, mantle, and core. The crust is the outermost layer and is made up of either dense oceanic crust or less dense continental crust. Below the crust lies the mantle, which makes up the bulk of the Earth's volume. At the center is the core, about 1/3 of the Earth's mass, which is mostly solid iron. The crust and upper mantle form separate tectonic plates that slowly move atop the asthenosphere.
Earth's layers power point notes
The Earth is divided into four main layers - the crust, mantle, outer core, and inner core. The crust is the thin outer skin of the Earth, making up only 1% of its volume. Below the crust lies the mantle, which is the largest layer and divided into upper and lower sections. Within the Earth is the core, with the outer core being liquid iron and the inner core being incredibly hot solid metals.
Minerals slideshare
1) Minerals are naturally formed solid substances with a crystal structure that are not alive and have a definite volume and shape.
2) All minerals share characteristics of being formed by natural processes, having a unique chemical makeup, and being made up of particles arranged in a repeating crystal pattern.
3) Minerals are grouped based on their chemical composition, with the most abundant group being silicates containing oxygen and silica like quartz and mica.
Minerals
This document discusses minerals, their economic importance, depletion, and the need for conservation. It notes that minerals are essential resources but non-renewable, as their formation occurs over millions of years. While minerals provide the base for industry and jobs, the large-scale exploitation since the Industrial Revolution has resulted in decreasing supplies and increasing demand. Conservation efforts are needed to use minerals sustainably and reduce waste so they can last for future generations.
Lesson 1 - 'Layers of the Earth' PowerPoint
The document describes the four main layers that make up the interior of the Earth: the crust, mantle, outer core, and inner core. It provides details on the composition and characteristics of each layer, including their varying temperatures and materials. Specifically, it notes that the crust is the outermost solid layer, the mantle makes up 84% of the Earth's volume and flows slowly, the outer core is a liquid layer of molten iron, and the inner core is a solid ball of iron alloy.
Rocks
Rocks are naturally occurring mixtures of minerals, mineraloids, glass or organic matter that are divided into three main types - igneous, sedimentary, and metamorphic - based on how they were formed. Rocks are continually changed over time by various geological processes through the rock cycle, where one type of rock can be transformed into another through weathering, erosion, melting and other changes. The core, mantle and crust act as a recycling machine that redistributes rocks.
Types Of Rocks
Sedimentary rocks form from the compaction and cementation of sediments and sometimes contain fossils. Igneous rocks form from the cooling of magma, either underground as intrusive rocks with large crystals or above ground as extrusive rocks with small crystals. Metamorphic rocks form from the alteration of existing rocks by heat, pressure, or chemical changes and may contain interlocking crystals or foliation.

Air Masses and Fronts
Maritime tropical air masses form over warm waters and bring warm, moist air into parts of the United States. Continental polar air masses form over snow-covered northern Canada and bring cold, dry air into central and eastern portions of the country. When warm and cold air masses meet, fronts are formed. Cold fronts have steep slopes that can produce heavy precipitation like thunderstorms and hail, while warm fronts have more gentle slopes and cause lighter, longer-lasting precipitation from nimbostratus clouds. Occluded fronts occur when a cold front catches up to a warm front.

Classification of Air Masses ( Climatology) .pdf
About air masses and it's major types with necessary image .Related course Climatology.Air mass is a volume of air defined by its temperature and water vapor content. Air
masses cover mant thousands of miles and adapt to the characteristics of the surface below them.
They are classified according to latitude and their continental or maritime source regions.
Cold air masses are termed polar or artic,while warmet air masses are deemed tropical. Continental and
superior air masses are dry while martime and monsoon air masses are moist.Weather fronts separate air
masses with different density (temperature or moisture) characteristics.An air mass may be defined as a large body of air whose physical properties especially temperature,
moisture content and lapse rate are more or less uniform horizontally for hundreds of kilometres".
According to A.N. Strahler and A.H. strahler (1978)"a body of air in which the upward gradients of
temperature and moisture are fairly uniform over a large area is known as an air mass".
Any classification of air masses must consider the fact that all of their weather characteristics (mainly
temperature, humidity and lapse rate) are properly represented and incorporated. Thus the weather
conditions of air masses at their source regions and thermodynamic and mechanical modifications
introduced in them during their journey away from their respective source regions must be taken into
definite categories.
There are two approaches to the classification of air masses.

The Queen Conch Bahamas BJC Review
The queen conch is a large edible sea snail native to Caribbean coasts. It has a spiral shell up to 1 foot long, created by the conch's mantle tissue. Conchs are herbivores that eat algae using a radula tongue. They are divided into a head, visceral mass, and small foot, and use tentacles for smell, touch, and eyespots. Overharvesting for food and decoration has depleted populations, leading to fishing restrictions. Conservation efforts include size and harvesting method limits.
Slave-life-in-the-bahamas
This document describes slave life on a plantation in the Bahamas in the early 1800s. It details the layout of the plantation, including slave quarters located away from the main house. Slaves grew crops like cotton and corn and raised livestock. Their daily tasks involved agriculture, construction, fishing, and crafts. In their spare time, slaves entertained themselves through African traditions like storytelling, music, and dance. Punishment of slaves was harsh, but acts of resistance still occurred sporadically across the islands.
Agriculture-Commercial Farming
Commercial farming involves growing crops or raising livestock to sell for profit. There are several types of commercial farming: mixed crop and livestock farms grow both crops and animals; ranching specializes in grazing livestock; dairies produce milk and dairy products; and large-scale grain farms primarily cultivate grains for export. Plantation farming produces crops like coffee, sugar, and cotton on large estates, often in developing countries, for export markets.
Forms of Government
This document compares different forms of government around the world. It discusses monarchies, dictatorships, theocracies, single-party states, parliamentary democracies, and presidential democracies. For each system, it provides a definition and examples of modern countries that demonstrate that form of government. It notes that while most countries have some form of government, the main models that exist are rule by a single person, rule by an elite group, and rule by the broader population.
Hedonism
Hedonism is the belief that pleasure is the most important thing in life. There are two main types of hedonism - psychological hedonism and ethical hedonism. Psychological hedonism claims that pleasure and pain alone motivate us or determine what is valuable. Ethical hedonism holds that our fundamental moral duty is to maximize pleasure and happiness, as advocated by Epicurus who taught that all actions should aim to minimize pain and maximize pleasure.
Ethical Egoism
The document discusses different perspectives on ethical egoism and the moral duty to help others in need. It presents arguments that ethical egoism fails as a moral theory because it arbitrarily assigns greater importance to one's own interests over the interests of others without justification. There is no inherent difference between oneself and others that makes self-interest morally superior. The document also argues that we should care about the interests of others as much as our own because their needs and desires are the same as our own. If we believe our own needs deserve to be met, then the needs of others deserve to be met as well.
Utilitarianism
The document discusses the moral philosophy of utilitarianism. It provides information on the key concepts of act utilitarianism and rule utilitarianism. Act utilitarianism evaluates the consequences of individual acts, while rule utilitarianism focuses on following rules that maximize well-being. The document also contrasts the views of Jeremy Bentham and John Stuart Mill on utilitarianism and discusses how the philosophy addresses various moral issues.

Weather
Weather is influenced by temperature, humidity, and air pressure. It describes the current condition of the atmosphere like sunny, windy, or rainy. Climate refers to the general weather conditions of an area, like the tropical climate in the Bahamas. Meteorologists study weather and how factors like changes in air pressure cause weather to change. Air pressure is caused by the weight of air in the atmosphere and can be measured with a barometer.

There are three main types of clouds: cirrus clouds, which are thin and wispy ice crystal clouds found very high in the sky; cumulus clouds, which are puffy cotton-like clouds that can signal either fair weather or rain depending on whether they are white or dark; and stratus clouds, which are the lowest, flat clouds that are often dark and can signal rain or fog if close to the ground.
Air Pressure
Air pressure is caused by the weight of the atmosphere pressing down on Earth. It changes with altitude and temperature. Low pressure occurs when air rises, leaving an area where it is pressing down less. Low pressure brings thunderstorms in warm, humid places. High pressure occurs where air is sinking, pressing down harder and usually bringing sunny weather, such as in cold places. Differences in heating cause uneven patterns of high and low pressure that drive wind as air moves from high to low pressure areas. Air pressure is measured using a barometer and is influenced by temperature, humidity, and altitude.
The Eleutheran Adventurers
A group of 70 European adventurers arrived in the Bahamas in 1647 from Bermuda seeking religious freedom to worship outside the Anglican Church. They sailed to Eleuthera island where they wanted to establish freedom and justice for all. However, after the captains argued and supplies were lost in a shipwreck, they faced harsh conditions and many left for a new island they named Sayle's Island, later renamed Providence, finding hope there.
The Loyalist
The Loyalist were American and British colonists who remained loyal to Britain during the American Revolution. Many Loyalists fled to The Bahamas after the war. They settled primarily in Abaco and Eleuthera, working as fishermen, boat builders, carpenters, plantation owners, farmers, and merchants. The Loyalists contributed greatly to developing The Bahamas by establishing infrastructure like schools, docks, and streets, as well as creating laws, newspapers, and a police force.
Ethiopian eunuch
The document provides background on the Ethiopian eunuch in Acts 8:25-39. It describes Philip as one of the first deacons who began preaching in Samaria after leaving Jerusalem. The Ethiopian eunuch held an important position in the queen's court in Ethiopia and had traveled over 1,000 miles to worship in Jerusalem. Philip met the eunuch and preached Jesus to him, including the need for baptism. The eunuch was immersed in water immediately after believing. The document emphasizes that true Bible baptism involves immersion and is a spiritual act, not an emotional one, and is necessary for salvation.
Eucharist
The Eucharist, also known as Communion or mass, involves the breaking of bread and drinking of wine in remembrance of Christ's death. It is celebrated in the Anglican and Catholic churches as mass and in other denominations as the Breaking of Bread during weekly or monthly services. The mass is divided into two parts - the Liturgy of the Word which involves readings, homily, and creed, and the Liturgy of the Eucharist in which the bread and wine are blessed and consecrated and subsequently consumed by participants.
Bodies of water
The document discusses the five main oceans of the world - the Pacific, Atlantic, Indian, Southern, and Arctic oceans. It provides data on the size and depths of each ocean, with the Pacific being the largest and the Mariana Trench in the Pacific being the deepest location at over 36,000 feet deep. Rivers are described as large bodies of fresh water that flow across land into seas or oceans, while lakes are bodies of fresh water surrounded by land.
Types of Map Scales
- A map scale indicates the relationship between distances on a map and in real life, allowing for accurate representations though smaller or larger than reality.
- There are three types of map scales: word scale, linear scale, and ratio scale. A word scale states the distance represented by 1 cm, a linear scale graphically shows a distance, and a ratio scale compares map units to real-world units.
- Ratio scales can be difficult to comprehend, so they are often converted to a word scale using a system like metrics. For example, 1:25,000,000 could be changed to 1 cm = 250 km.
- Maps are categorized as large or small scale depending on the level of detail. Small scale

APM event held on 9 July in Bristol.
Speaker: Roy Millard
The SWWE Regional Network were very pleased to welcome back to Bristol Roy Millard, of APM’s Assurance Interest Group on 9 July 2024, to talk about project reviews and hopefully answer all your questions.
Roy outlined his extensive career and his experience in setting up the APM’s Assurance Specific Interest Group, as they were known then.
Using Mentimeter, he asked a number of questions of the audience about their experience of project reviews and what they wanted to know.
Roy discussed what a project review was and examined a number of definitions, including APM’s Bok: “Project reviews take place throughout the project life cycle to check the likely or actual achievement of the objectives specified in the project management plan”
Why do we do project reviews? Different stakeholders will have different views about this, but usually it is about providing confidence that the project will deliver the expected outputs and benefits, that it is under control.
There are many types of project reviews, including peer reviews, internal audit, National Audit Office, IPA, etc.
Roy discussed the principles behind the Three Lines of Defence Model:, First line looks at management controls, policies, procedures, Second line at compliance, such as Gate reviews, QA, to check that controls are being followed, and third Line is independent external reviews for the organisations Board, such as Internal Audit or NAO audit.
Factors which affect project reviews include the scope, level of independence, customer of the review, team composition and time.
Project Audits are a special type of project review. They are generally more independent, formal with clear processes and audit trails, with a greater emphasis on compliance. Project reviews are generally more flexible and informal, but should be evidence based and have some level of independence.
Roy looked at 2 examples of where reviews went wrong, London Underground Sub-Surface Upgrade signalling contract, and London’s Garden Bridge. The former had poor 3 lines of defence, no internal audit and weak procurement skills, the latter was a Boris Johnson vanity project with no proper governance due to Johnson’s pressure and interference.
Roy discussed the principles of assurance reviews from APM’s Guide to Integrated Assurance (Free to Members), which include: independence, accountability, risk based, and impact, etc
Human factors are important in project reviews. The skills and knowledge of the review team, building trust with the project team to avoid defensiveness, body language, and team dynamics, which can only be assessed face to face, active listening, flexibility and objectively.
