Hi There,

I'm trying to make sense of the GFS 500hPa charts on Wetterzentrale
but to be honest I'm not really sure what I'm looking at. *The High
Pressures & low pressures are easy enough to figure out but what
exacly do the colours refer to. *Assuming they are temperature
gradients do they refer to surface temperatures or something else.

Any advice anyone could give (in layman's terms i'm afraid) would
be very welcome.

Many thanks

David.
