I have tried to find information about how Rocksim uses "thermals". Under the launch conditions tab while in simulations, there are about 9 different thermal settings. If I just google thermals, it seems there is more to know than I need in Rocksim. Can someone please direct me to a simple tutorial about what these mean and how they affect rocket flight? I must be the only one flying who doesn't know or understand this. I cannot can't find anything on the Apogee site about it either.
