any of you understand clearly how the weight variable works in the environment.xml file?
Here is the "winter" section of the yukon valley environment.xml file as an example.
There is weight here and there and I am really not sure how it operates. I feel that the weight play something in the random throw for selecting the daily weather, but it is really shady to me. In many maps, I saw it varying from 1 all the way up to 95. I would really like to understand clearly how this value is used by the application.
Please enlighten me if you figured this one out!
