2005年登陆我国热带气旋特征分析

Features of the Tropical Cyclones Landing on China in 2005

热带气旋是影响我国沿海的主要灾害性天气系统之一,它产生的狂风、暴雨、巨浪和风暴潮,给沿岸地区人民生命和国家财产安全带来严重威胁。而严重的台风灾害,往往是台风登陆引起的。为进一步研究登陆热带气旋的活动规律,总结了2005年登陆我国热带气旋的特点,结果表明:2005年登陆我国热带气旋具有登陆季节短、登陆地点分布异常、台风比例异常偏高、灾害损失极为严重的特点。同时,还讨论了2005年登陆我国热带气旋异常的气候原因,并指出未来几年登陆热带气旋和台风的年频数处在上升趋势中。

The tropical cyclone is one of the most catastrophic synoptic systems which influence the coastal regions of China. The gales, the storms, the billows as well as the storm tides, which could be brought by the tropical cyclones, can cause a great threat to the safety of the coastal people＇s lives and properties. Moreover, the worse disasters are always brought by the landing of the tropical cyclones. To better understand the rules of the tropical cyclones landing on China, the features of the tropical cyclones which land on China in 2005 are analyzed. It concludes that,in 2005, the landing season of the tropical cyclones is short, the landing points distributes unusually, the percentage of typhoons is unusually high and the loss is extremely serious. Furthermore, the climatic reasons of the phenomenon are discussed, and it is pointed out that the frequency of the tropical cyclones and typhoons landing on China per year is on the rise in future years.
