武汉和宜昌地区降水的Z-R关系

THE Z-R RELATIONSHIP OF PRECIPITATION IN WUHAN AND YICHANG AREAS

应用1987—1989年观测的850份雨滴谱资料,统计分析了武汉和宜昌地区降水的Z-R关系。得出武汉地区:层状云降水Z=200.7 R^(1.259) 对流性降水Z=292.4R^(1.265) 宜昌地区:层状云降水Z=259.3R^(1.407) 对流性降水Z=361.9R^(1.477)

Having analyzed 850 raindrop size data from 1987 to 1989, we obtain the following regressional formulas of radar reflectivity factor (Z) and precipitation intensity (R): (1) Wuhan Area: precipitation from stratiform clouds: Z=200.7R^(1.259) precipitation from cumuliform clouds: Z=292.4R^(1.265) (2) Yichang Area: precipitation from stratiform clouds: Z=259.3R^(1.407) precipitation from cumuliform clouds: Z=361.9R^(1.477)
