Reposted from The Cliff Mass Weather Blog Weather Radar Shows Spring Bird Migration Every day I have been checking the weather radar for signs of the northward migration of our feathered friends, and Wednesday night I finally saw it. Ornithologists and those tracking the seasonal migration of birds have used weather radar for decades. The…
This AGU session asked that question directly and I covered this previously. Now that the video of the entire session is available, I thought it worth revisiting. Of course, the answer is “no”, even when they try to make a hockey stick out of it. Watch the video, especially at just before the 20 minute…
I’m caught between sessions but wanted to post this. From a presentation at AGU that I couldn’t attend. This from SciAm: James Elsner at Florida State University has a killer curve, and lots of caveats. The curve indicates that tornadoes in the U.S. may be getting stronger. The caveats indicate they may not be. “If…
“Chaotic wind velocities associated with the rotating turbine blades triggers the doppler radar mesocyclone detection algorithm” Note: this essay was written by the National Weather Service Forecast Office is Burlington, Vermont and tipped to me by a reader. Vermont’s wind farm acreage pales in comparison to places like the Texas and Oklahoma, where there are…
By Paul Homewood http://news.fsu.edu/More-FSU-News/Researchers-develop-model-to-correct-tornado-records [Note Update Below] Quantification of long term tornado trends has been hampered by the fact that many more tornadoes are reported today than was the case in the past. NOAA summarise this well:- With increased national Doppler radar coverage, increasing population, and greater attention to tornado reporting, there has been…
