Re: Transition to extratropical?

I checked the entire message. XXAA are mandatory and XXBB/XXCC are signficant levels are represented by 11, 22, 33, 44, 55, etc followed by the millibar level. Within the XXBB data set I noted "21212" followed by wind data groups.

A quick tutorial; positive temperatures are even numbered; negative temperatures are odd numbered.

I've copy and pasted this snippit from below:

21212 00999 12513 11994 14013 22991 13523 33892 09525 44890 08016 55887 06512 66876 06015 77871 05513 88857 07011 99851 11007 11840 14506

00999 12513 is a wind group. A temperature of 12.5? What do we know about odd temperature groups? 22991 is 13523, 33892 is 09525, 44890 is 08016, 55887 is 06512, 66876 is 06015, 77871 is 05513, 88857 is 07011, 99851 is 11007 and 11840 is 14506.

A closer look at 99851 in the XXAA grouping is the 850 mb wind; they match, both a wind direction from 110 at 07 knots. The temperature at 850 was 19.6C and a dew point depression of 3.4 or a dew point of 16.2
At the surface the temperature was 23.4 and a dew point depression 0.2 or dew point of 23.2

Feel free to let me know what y'all think; thanks!
