Water Vapor - IR3

Watch the t-storm complex in west Texas launch
two gravity waves westward. The second lasts a long time
and goes a long way, before dissipating.

Actually, this is a fairly common occurence. It is best seen, in my
opinion, in the water vapor channel. I routinely watch for gravity
wave packets moving away from convective clusters in the southern
U.S. and in Mexico.
