I worked with meteorology guys in air battle planning. Laser guided weapons don't work so well when it's foggy or dusty, so we always had the WX guys give us their forecast and then they sat in the OpCell working mission replanning as weather became a factor.
There were a bunch of weather guys at one of my assignments who either ended up in pilot training or doing the weather at the 11 o'clock news, so everyone thought that was a good field to get into.
I'm not sure what all science was entailed in it, but I know that some days it looked like pure magic and others it looked like they were just making random selections out of a hat.
