Bright band is meaningful for stratus precipitation mechanism research and weather modification. By using the observed data of wind profile radar of different types of precipitation in Beijing from April to September 2010, this paper puts 〖JP2〗forward the bright band recognition algorithm, distinguishing bright band information from precipitation data by the corrected recognition algorithm, and obtaining the height and duration of bright band as well as the comparison of precipitation amount and precipitation type in Yanqing, Beijing. According to the statistical result, the distribution characteristics of the melt layer in Yanqing, Beijing in the summer of 2010 are got. The maximum of echo intensity mainly appears in 36-40 dBz, the thickness of bright band is 1000-1500 m, and the difference of upper and lower boundary velocity is 4-5 m·s-1.〖JP〗
