中文摘要: 为探讨对我国产生严重影响的登陆北上台风的成因,利用1975—2005年台风资料及NCEP/NCAR逐日再分析等资料,分析了登陆北上台风的气候特征及其大尺度环流和物理量分布特征。结果发现,不仅西北太平洋副热带高压位置和强度变化对台风登陆北上起决定性作用,而且西风带系统和南亚高压活动有利于台风登陆后北折和持续北上也有不可忽视的影响。总结归纳台风登陆北上的预报着眼点,希望有助于提高此类台风的预报预警能力。

Abstract:Using observational data and daily NCEP/NCAR reanalysis dataset during 1975—2005, the climatic features of landing and going northward typhoon, the corresponding large-scale circulation patterns and the distributions of the meteorological parameters during the landing periods are discussed. Results show that the variation of the position and the intensity of the western Pacific subtropical high play a crucial role in going northward typhoons. Furthermore, the middle-latitude westerlies systems and the South Asian High actions have an important influence on typhoon′s northward movements. Above results are hoped to be helpful in the track prediction of landing typhoons.
