A Study of Drop-Size Distribution in Precipitation Cloud from Wind Profile Radar

Author retrieves the raindrop size distribution in precipitation, by separating two distinct return signals from clear-air and from precipitation, based on the return signal spectrum density derived from the wind profile radar, and on the relationship between the terminal velocity and the diameter of descending raindrops. Further retrieval of precipitating cloud data at different heights has resulted in the raindrop size distribution indicating a basic match with the distribution of M-P distribution. The reflectivity value derived from wind profile radar is in agreement with that from Doppler weather radar. Calculating the water content in the clouds at different heights through a raindrop size distribution reveals that is close to the water content observed by the Weather Doppler Radar.
