热带气旋的温带变性过程对下游影响的研究进展
RESEARCH PROGRESS ON THE IMPACT OF EXTRATROPICAL TRANSITION OF TROPICAL CYCLONE ON THE DOWNSTREAM FLOW
摘要
Abstract
As a tropical cyclone(TC) moves northward,it often transforms into an extratropical cyclone,which is known as an extratropical transition (ET) process.An ET process involves the complex interaction between the tropical systems and the midlatitude flows,which not only changes the local atmospheric state around a TC but also affects the atmospheric circulations over a larger region.Especially,the downstream impacts are much more obvious.ET and its downstream impact often lead to serious disasters in the midlatitudes,and its accurate forecast is still difficult.Therefore,scientific research and operational forecasts concerning the ET process and its downstream impact become current hotspots.In this work,the international and domestic progress in the interaction of TCs with midlatitude flows,the downstream impacts of ET systems,the numerical forecast of the downstream impacts are summed up and analyzed.关键词
