摘要
本文以 1949～ 1998年福建台风资料为素材 ,分析了登陆闽南地区台风的活动规律及其若干影响因素。结果表明 :登陆闽南地区台风个数常年为 1.3 5个 ,7月下旬至 9月中旬为主要活动时段 ;在台风活动过程中 ,存在着比较明显的准 2～ 3a和准 19a活动周期 ,并具有间隔 11a的反相关趋势 ;50 0hPa东亚环流与登陆闽南地区台风关系在高、中、低纬度上呈“ -、+、-”的相关关系 ;黑潮与西风飘流区海温场呈正相关关系。
According to typhoon data of Fujian during 1949～1998, the activity regularity and several kinds of affecting factors of typhoon landing in south Fujian are analyzed and the results are as follow. (1)There are usually 1.35 typhoons that land mostly from July to September in the region every year. (2)There are apparent quasi cycles of 2～3a and 19a and anti correlation trend every eleven years in the course of typhoon activities. (3)The correlation between the typhoon and East Asia circulation of 500hPa geopotential height fields is respectively negative,positive and negative in the high, middle and low latitudes. (4)There is positive correlation between Kuroshio Current and the West Wind Driftage Zone in the sea surface temperature.
