sun–weather correlation—A relationship claimed to exist between solar phenomena and tropospheric weather phenomena.
sunglint—The portion of shortwave radiation illuminating a water surface that is reflected back to space. This reflection appears in visible imagery as a bright area on an otherwise dark water area when winds are light and the water surface is smooth. The rougher the water, the more diffuse the glint pattern.
sunlight—Light from the sun; also called sunshine. The majority of the energy from the sun is divided into three parts: ultraviolet radiation, wavelengths less than about 0.4 μm; visible radiation, wavelengths between about 0.4 and 0.7 μm; infrared radiation, wavelengths greater than about 0.7 μm. There are conflicting conventions as to whether all three regions are referred to as light, or whether that term should only be applied to the visible portion of the spectrum. The ultraviolet radiation is sometimes called short waves and the infrared region, long waves. 's Nautical Almanac Office
sunlit aurora—An aurora that occurs in the sunlit part of the upper atmosphere above the earth's shadow. Sunlit auroras have been observed to extend up to about 1000 km.
