The RAOB launch site is just under a mile from the ASOS, so it is possible that there was considerably more wind at the launch site that at the ASOS. However, usually it works the other way around in these kind of situations, with the upper air site colder that the ASOS. The UA site is much more sheltered by trees than the ASOS, which is on the south end of the runway, far from any trees or buildings of any size. <br /><br />We are getting to the super inversion time of year, and those kind of vertical temp differences will likely occur over the next few months. I may have posted some point in the past about Fairbanks's most extreme inversions, but I'll try and do up another one sometime soon. <br /><br />RickRickhttps://www.blogger.com/profile/03946704894714514716noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-91185733428909155242012-11-01T13:11:29.327-08:002012-11-01T13:11:29.327-08:00Thanks for posting, I was curious how unusual yest...Thanks for posting, I was curious how unusual yesterday's strong winds were.<br /><br />It was amazing to see the temperature plummet ("smartly" indeed!) at Fairbanks this morning once the winds finally died down. I'm slightly puzzled by the 12Z sounding, which showed a temperature of -8.5 C at the lowest level, listed as 135 m and presumably essentially at ground level. At the same time PAFA reported -14.4 C, later dropping as low as -22.2 C! I assume this means the cold layer was *extremely* shallow and wonder if this is typical?<br />Richard Jamesnoreply@blogger.com
