If you mean how can we forecast the weather, it's largely a matter of  measuring teh movement or change of wind currents, humidity, and a number of other factors.  Now, most of that is fed into a computer, and it gives aprediciton of what the weather will be over a short period of time.  Or, you could use an ancient Indian weather rock:  If it's hot, the sun is out; if it's wet, it's raining; if it's swinging, the wind is blowing...

...I don't exactly know...Though my teachers have said in the past that if it rains, or any thunder/lightning, or if there is dangerous weather (looming) that we should go inside. If it sprinkles, my teacher still made our class run- through the mud, too! That's why we have uniforms for p.e., so that when we wear our normal clothes, it wouldn't be all muddy and dirty- Though if it starts pouring, our teacher would tell us to go into the gym. I mean if the school is the cause of one's sickness because they got a cold from the rain or something, that's bad for the school/ ..Anyway, I think the rules vary from each school. I mean it can't be like extreme temperature- if it was snowing, or was like burning fire( eh, not really, we still stay out during the hot times)...but like yea.
