These details were pulled right from the game's source code by modders, and apart from the weather effects, I don't think this information was ever mentioned publically by the developers.

At some point I will be making a "racial tags" page under Game Mechanics, which will list all classifications in the game and what they do. And possibly even mention the number of units with each tag.
