摘要
首先对登陆我国台风活动的气候特征分析指出,登陆我国的台风频数存在明显的月际、年际和年代际差异;登陆台风具有明显的周期特征和时间日变化特征;并指出了登陆我国台风与厄尔尼诺的联系。对中心最大风速≥17.2m/s的登陆台风移动趋势进行了统计分析,结果表明不同移动趋势的登陆台风频数不仅与季节有关,还与登陆地段有关。其次总结了近几十年有关登陆台风研究的成果。
Climatic characteristics of the landing typhoons are studied by means of statistical method.Results show that the landing typhoons have obvious intermonth,interannual and interdicadal variations,marked periodical character,and daily variation.Furthermore,statistical study on motion tracks of China landing typhoons(velocity is equal to or above 17.2 m/s) is given in this paper. Resulsts show that motion tracks of the landing typhoons is not only related to the season but also to the landing position.Recent progress of study on China landing typhoons in recent years are also summarized in this paper.
