Original Note:
This is incorrect. The blue and green circles around the radar are called anomalous propagation, specifically radar bloom. This is caused by superrefraction of the beam due to air density gradients like temperature inversions. Nexrad does NOT affect weather! https://medium.com/weather-wisdom/radar-beams-refraction-inversions-and-ground-clutter-4b7dec0df821 https://www.noaa.gov/jetstream/radar-beams https://www.accuweather.com/en/weather-blogs/weathermatrix/anomalies-radar-bloom-ducting-explained/99303 https://www.roc.noaa.gov/public-documents/operations-branch/Data_Quality_Oddities_and_Anomalies.pdf https://www.theweatherprediction.com/habyhints2/391/ https://www.ametsoc.org/amsedu/Anim/img_loops/LargeRad/index.html#:~:text=For%20example%2C%20a%20strong%20temperature,stronger%2C%20and%20grainier%20in%20appearance https://courses.comet.ucar.edu/pluginfile.php/3704/mod_imscp/content/1/anomalous_propagation.html
