Probing Air Motion by Doppler Analysis of Radar Clear Air Returns

摘要: Abstract A Doppler radar has been used in central Oklahoma to probe the motion of invisible targets usually referred as “angels.” The large density detected on certain days suggests presence a dense atmospheric “plankton” drifting with air. Uniform for all area surveyed by beam is confirmed systematic pattern target radial motions function azimuth. Target horizontal direction and speed are derived from velocity-azimuth patterns interpreted wind. small vertical also estimated data. This technique applied analysis wind variance study low-level jet.
