摘要
对近50年影响舟山的台风气候特征进行了分析。结果表明:影响台风具有明显的年际和月际变化特征;影响路径主要有登陆型和海上转向型两种;台风影响程度与其移动路径、登陆时的中心强度以及登陆后的维持时间密切相关。台风暴雨地理分布呈现出北部少,南部多,东部少,西部多的特点,灾害性台风大风分布却正好相反。近海转向类、登浙类及登闽类台风是引起舟山台风强降水和灾害性大风的主要移动路径。最后,总结得出了严重影响的四类台风暴雨和二类台风大风环流特征。
The climatic characteristics of typhoon influenced Zhoushan over the past 50 years are analyzed. It is found that the typhoons show distinct annual and monthly variations. The typhoon impact is closely related to its moving track, intensity at landfall and duration time after landfall. Analysis also shows that heayy rain driven by typhoon occurred at the north/east of Zhoushan is less than that at the south/west, while the situation of disastrous gale is opposite to the heavy rain. Typhoons shifting to the offshore sea, landing on Zhejiang and Fujiang prov- ince are the main tracks which have correspondence with strong rainfall and disastrous gales. Finally, the serious impact of four typhoon storms and two wind circulation features of typhoon are concluded.
