Abstract

Abstract

Study is performed on climate features of rainfall from typhoons of diverse paths in East China with main affecting factors investigated. Results suggest that the intrusion of cold air, topography, moisture and the duration are main contributing factors to rainfall. Two physical quantities are given for diagnosing the rainfall. And calculation indicates that the accuracy of forecasted thermal divergence is 32/34.
- Typhoon rainfall;
- Factor analysis;
- Thermal divergence
