Note the obvious
differences between thermal IR (usually just called IR) and water vapor IR
(usually just called water vapor) images from the same satellite at the same
time
|
|
Infrared has more discrete areas of
clouds; water vapor is more continuous
|
|
It is easy to tell from thermal IR the
cloud top temperature; water vapor is more ambiguous
|
|
The presence of the polar front jet is
easy to see in water vapor imagery, even without the presence of a comma
cloud or baroclinic leaf
