Visible -vs- Infrared -vs- Water Vapor
reflectivity -vs- temperature -vs- moisture
Images (a), (b) and (c) are examples of visible
and infrared and water
vapor
satellite images
respectively (valid for the same time).
The thunderstorms (areas of bright white)
that broke out from Mississippi to South Carolina stand out more
vividly in the infrared
and water vapor images than in the visible.
Drier air filtering in behind the thunderstorms across Illinois, Indiana and
Missouri stands out very well in the water vapor image (c), however is not
as noticeable in the infrared (b) and visible (a) images.
