A Quantitative Study of Asymmetric Characteristic Genesis of Precipitation Associated with Typhoon Haitang
“海棠”台风降水非对称分布特征成因的定量分析

Typhoon Haitang landing Fujian Province from 0800 LST 19 July to 0800 LST 20 July in 2005,gives rise to a significant rain process during the 24 hours,and precipitation intensity on the north side of typhoon is stronger than that on the south side,which shows obvious asymmetric distribution.The rainfall process is simulated using the WRF model and based on simulated outputs,the relative humidity and vertical ascending motion fields are analyzed,meanwhile,the forcing roles of orgoraphic lifting and surface f...
