摘要
本文利用1949—1984年有关台风及气象的历史资料,初步分析了台湾岛和台湾海峡地区台风异常路径的气候特征及成因,结果表明:1.由于本研究区所处的地理位置和特殊的地形条件,异常路径出现的类型独特,且出现机率高,时间集中。2.异常路径全年出现一个主高峰期和一个次高峰期,它们与副高季节性变化有较好的关联。3.地形的影响,可使台风环流结构改变,并可诱生地形槽或低压中心,导致台风异常路径的出现。
By using data set from the years of 1949—1984,the climatic statistic and preliminary analysis of the typhoon’s anomalous path over the Northwestern Pacific Ocean across Taiwan Island and Taiwan Strait,are made.1.The appear once of the typhoon’s anomalous path in Taiwan Island and Taiwan Strait,due to specific geographical location and geomaphology,is high in probability and relatively concentrated in appearance period.2.Annual peak and subpeak of typhoon’s anomalous paoth appearance is correlated with the subtropical anticyclone’s seasonal change.3.The geomorphological effects not only change typhoon’s circulation construction,but also induce geography trough or the low center.With strong vitality,the formation of meso and micro scale weather systems may affect typhoon’s movement and cause the appearance of anomalous path.
