Water Vapor Satellite Image Animation

Water Vapor Image - The water vapor image shows an infrared band which is affected strongly by the presence of water vapor. Essentially, the image shows the altitude of the highest moist layer in the atmosphere. Bright areas of white and darker green reflect the location of high clouds either due to jet stream cloudiness or due to thunderstorm activity. The dark blue areas reflect the location of dry air at high altitudes. This is associated with dry air intrusion and sinking motion associated with high pressure systems.
