Hi Guys, I received the following from a helpful person at the Met bureau in response to a question about how to read their temp traces, which are available from the Met Bureau web site under "aviation" (I think, if my memory is correct) Thanks to Mark for making these charts easily available to us. Pity there is nothing for our Club between Melbourne and Wagga. However, beggars etc....
Cheers, John G.

The pressure scale is | logarithmic, which makes it linear with respect to height. The other axes | shown are the mixing ratio (the green dotted sloping straight lines near the | bottom and the dry and saturated adiabats, the green dotted curved lines). | The grey curved line near the centre shows the temperature a parcel of | surface air would have if it were lifted. | | I agree that it would be good to have more explanation on our web site. | | I trust this information is helpful. Please don't hesitate to contact us | again if you require further help. | | > | ----Original Message----- | > | From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] | > | Sent: Thursday, 29 November 2001 05:56 | > | To: [EMAIL PROTECTED] | > | Subject: Aviation Industry/Question/Australia-Wide/Climate and Past | > | Weather | > | | > | Reference ID = 'REF2001-333-9' | > | Name = 'John Giddy' | > | E-mail address = '[EMAIL PROTECTED]' | > | Phone Number = (03) 9818 4524 | > | | > | John Giddy wrote:- | > | | > | Could you please supply some notes on how to read the Stuve | > Diagrams which | > | are now available on this web site.
