The Atmosphere Dynamic and Thermal Energy Characteristics of the Typhoon Rainstorm affecting Guilin and the Examination of Japanese Numerical Forecasting Products in Recent Years

This Paper studies the large and medium-scale circulation background situation of the typhoon rainstorm affecting Guilin in recent years, and emphatically compares and analyzes the thermal and dynamic Energy Characteristics of the rainstorm of typhoon Ute and Hornet. The compared result indicates: the rainstorm caused by the superimposition of upper-air trough and the typhoon trough is far more serious than that of the single and pure typhoon circulation. And it explains that the interaction of the low-latitude weather system can create the increased range of the rainstorm. Meanwhile the forecast capability of the Japanese numerical forecasting products for the typhoon rainstorm is examined and the result indicates that The Japanese numerical forecasting products show better forecast capability on the rainstorm caused by typhoon circulation itself.
