Synthetic Aperture Radar (SAR) winds are derived from a microwave signal pinged from a satellite; backscatter is converted into winds (given a background field that is typically from a numerical model). The wind structure here is suggestive of a bowing feature to a convective downdraft. How does it compare to... Read More
Clear skies over the Great Lakes (except for Lake Superior) allowed for VIIRS data to record temperatures over the Great Lakes in the early morning of 5 August 2021. In situ data from moored buoys closely match ACSPO (Advanced Clear-Sky Processor for Oceans) values. Southwestern Lake Erie is warmest, with temperatures as warm as... Read More
The animation above shows NUCAPS sounding availability plots from sequential NOAA-20 overpasses on 5 August 2021. Stations that are north of about 39 N will occasionally see profiles from two sequential overpasses, as was the case above at Buffalo NY, and also Pittsburgh PA. A benefit of NUCAPS soundings is...
