12z 16z 18z 0z.. What Do They Mean?

Hey,

I don't mean to sound an idiot, but what do the 0z 12z 18z blah blah runs exactly mean?

I'm guessing they're the times of the model runs. ie 18z is at 6.00pm? z being zeit (German for time)?

This specific guide should answer most of your queries, and the guide section in general should answer many questions on weather charts.

They are the times the models were run in GMT.

The date on the left is the date at which the model was run and the date on the right is the date the chart is for.

Sun,20 November 2005 12z --- Mon,21 November 2005 18z

This would mean that the chart was run at 12:00 on 20th November and the chart is for 18:00 on the 21st November

I thought z was for zulu time, was when I was in the raf anyway. Used to pass the met forecasters upstairs all sorts of junk that made no sense to me!

Cheers, Rib.

Here's a link explaining Zulu time, but you can't read it because they've camouflaged the text. http://www.lerc.nasa.gov/WWW/MAEL/ag/zulu.htm
