西北太平洋热带气旋活动的纬度分布特征

THE LATITUDINAL DISTRIBUTION OF CLIMATIC CHARACTERISTICS ON TROPICAL CYCLONE ACTIVITIES IN THE WNP

摘要: 利用中国气象局整编的1949~1998年的热带气旋年鉴资料, 分析了西北太平洋热带气旋 (TC) 的源地、活跃地、变性和消亡地、北上率、变性率和消亡率及强度和移动等气候特征的纬度分布, 揭示了热带气旋在不同纬度带活动的一些基本事实, 旨在为进一步研究热带气旋与不同纬度带环流系统之间相互作用的物理机制奠定基础。

Abstract: Using the tropical cyclone (TC) yearbook data from 1949 to 1998, the latitudinal distribution of TC movement in the Northwest Pacific is analyzed. They include the climatic characteristics of TC genesis, active, extratopical transition (ET) and disappearance position; the ratios of TC north-toward moving, ET and disappearance; and the average intensity and movement.
