By means of the radial velocity and reflectivity data of Doppler radar precipitation products in Spring in the northern and central part of Guangdong, classification is conducted on the precipitation processes with potential for rain enhancement, and the vertically integrated liquid, intensity, and echomoving velocity are statistically analyzed. The best operation chances of rain enhancement for different cloud systems are presented. The appropriate operation heights for rain enhancement in spring in the northern and central part of Guangdong are given by analyzing echo top heights and temperature. The instability conditions such as the Convective Available Potential Energy (CAPE), influencing systems, and water vapor influx divergence favorable to rain enhancement, are analyzed. As an example, the application of the newgeneration weather radar products to the operation of rain enhancement is discussed.
