Wind Measurement Comparison Between Doppler Weather Radar and Wind Profile Radar
摘要
Abstract
Doppler weather radar data can be used to retrieve environmental wind vector and divergence at different heights by it’s radial velocity data with the assumption of linear wind field.Based on the assump-tion of isotropy and wind field coherence,wind profile radar can detect the locus three-dimensional wind field with the target of onflow.Doppler weather radar measures the mean wind field at different height within the large scale of 30 km,while wind profile radar can measure the locus three-dimensional wind field with high vertical resolution.The mechanisms of the two radars are different and spatial targets also have differences. The measurement results can supplement each other in the condition of high consistency and relativity,which may give much help for reasonable analyzing of the data provided by these two kinds of radars.关键词
