try our guides on skew-t charts, and that lengthy one I did taking you through each stage and what it means?

and some of the GFS chart viewer extra I havent a clue and was wanting to find out more.

eg, the hight of the degree isotherm and vertical verlocity.

do you mean this chart?

if so then its showing the zero centigrafe level, or 'freezing level' in metres, marked as shown but not explained down the right hand side?

any help would be much appricatied

vertical verlocity.

is this type of chart, the higher the number the more the air is rising at the level shown, in this case 300mb(30,000ft), rising air tends to give clouds and precipitation.

The negative numbers=rising air

+ve=descending air

I think!

any help to you?

very much thank you

my one suggestion would be that if possible some of the charts should have more information beside them. for novices like me.

[johnholmes]

talk to Paul about that

Taken from the helpfile on the new chart viewer:

We will be continuing to develop this system while it is in beta, so please do let us know any feedback that you have. Once out of beta, a guide to the various chart types will also be made available as part of the viewer.
