摘要
南海及其毗邻海域是西北太平洋热带气旋(TC)重要生成源地,提前和精准预测TC生成,是进行TC路径、强度变化和风雨预报以及减轻TC危害的前提。回顾梳理了近年来有关于TC生成的环境要素、物理机制、主要天气环流形势的相关研究进展。初步分析了TC初始扰动在有利环流背景条件下,菲律宾群岛地形动力作用对于南海及其毗邻海域TC生成的直接促进作用,并提出了一些与地形动力作用有关TC生成方面的科学问题。
The South China Sea and its adjacent basins are the key area for tropical cyclone(TC)genesis over the western North Pacific.Forecasting the location and timing of TC genesis accurately is preliminary important from a perspective of effective early warnings for disasters associated with TCs movement,intensity,and rainfall.This article reviews recent progress in understanding the environmental factors,key physical mechanisms,and surrounding weather patterns for TC genesis.The focus is on the dynamic effect of orography around the Philippine Islands for TC genesis from a pre-existing tropical depression under the favorable environmental influences over the South China Sea and its adjacent basins.Some open scientific issues on the dynamic effect of orography for TC genesis are highlighted.
