That's why some 404 people were on last time I checked, 25 off the record.

First column is time (GMT or EDT+4 hours). Second column is latitude in degrees and minutes (2528 means 25° 28'N, NOT 25.28N). Longitude is the third column, same format.

As for flight-level wind, those are the 6-digit groups. The first 6-digit group is the 30-second wind. The last 6-digit group is the 10-second wind. For both, the first three digits are the wind direction in degrees, and the other three digits are the measured wind speed in knots.

NOAA aircrafts are also equipped with SFMR, which estimates surface wind; these estimates can be found in the second-to-last column. As a bonus, SFMR also estimates rainfall, and that, in millimeters, is the final column.

mesmerized

#1709 Postby heatstroke » Sun Aug 28, 2005 2:21 pm

As a witness to the devastation of a large (1/2 mile wide) F5 tornado, I find myself both mesmerized by and terrified of what is about to happen...and that was just wind. The scale of this thing is difficult to imagine.
But like lots of others I desire all the information I can get.
Please keep up the great work for those like me.

Thanks
RC
