Automatic Identification and Correction Algorithm of the Bright Band Based on Wind Profil Radar Data
摘要
Abstract
The melting process in the melting layer gives rise to the enhancement of radar reflectivity, which is known as the 'bright band'.An automatic identification and correction algorithm of bright band is presented in this paper.This algorithm is developed from the characteristics of stratiform or blended precipitation based on WPR data in Fangshan,Beijing,from August to October 2014.A typical blended precipitation episode from 1 to 2 September 2014 is analyzed by using this algorithm.The identified bright band parameters are compared with sonde and Doppler radar data,which is verified to be reliable.After bright band correction,the high echo intensity areas are restrained,and the obvious curve of the vertical profile of echo intensity near bright band height disappears.关键词
