台风Danas(1324)对台风Fitow(1323)影响的诊断分析及数值试验
THE DIAGNOSTIC ANALYSIS AND NUMERICAL EXPERIMENT ABOUT THE EFFECT OF TYPHOON DANAS(1324) ON TYPHOON FITOW(1323)
摘要
Abstract
In recent years,some binary tropical cyclones often bring serious disasters to the affected areas,so the interaction between the two typhoons has received more and more attention.The effect of typhoon Danas(1324) on the typhoon Fitow(1323) was studied with the FNL data and WRF model.The results show that the intensity of the change of Fitow while before and after landing is directly related to the change of the eastern boundary water vapor transport channel,which link with Danas.Before Fitow landing,the water vapor channel is mainly caused by the environment field easterly stream on the southwest side of the subtropical high.Danas at the upstream intercepts environmental field delivering water vapor to Fitow and inhibited its development.However,Fitow after landing,Danas on the environment of the water vapor in turn plays a role in the transport,increasing the Fitow of the water vapor income,and increasing its north side of the strong precipitation.Danas,through water vapor as a link,affect the intensity of Fitow before its landing and Fitow's asymmetric precipitation distribution onshore.In addition,Danas's northward movement affects the intensity of subtropical high,causing the subtropical high's east back,changing Fitow's steer flow,affecting the Fitow landing position,and Fitow's counterclockwise spinning around the landing by applying the southward steer flow.关键词
