Original Note:
The NEXRAD radar loop shows examples of anomalous propagation (noisy false echoes caused by downward beam bending due to superrefraction from a low-level inversion) & bistatic coupling (interference when two radars sample the same part of the storm at the same time). https://www.roc.noaa.gov/public-documents/operations-branch/Data_Quality_Oddities_and_Anomalies.pdf https://www.roc.noaa.gov/public-documents/operations-branch/webinar-wsr-88d-interference.pdf https://www.noaa.gov/jetstream/radar-beams https://www.noaa.gov/jetstream/anomalous-propagation
