Hi everyone,
I've got a question about snow which i'm hoping you guys can answer for me.
Why is it that if its 2C in october or november if will quite often rain
instead of snow and yet come April it can be 7 or 8C and snow quite
readily. I'm guessing it has to do with the temperature of the surrounding
seas but i may be wrong.
Firstly I think it is to do with the thickness of the troposphere. See
http://homepage.ntlworld.com/booty.weather/metindex.htm for explanation
of thickness.
Secondly, it is to do with dryness of the air, if the air is dry enough,
any snow falling will not melt into rain.
