根据中国政府的记录，我们对 1450 年至 1949 年期间登陆中国东部沿海的热带气旋数量进行了调查。研究发现，这一时期每年登陆华东地区的台风数量呈现正向且统计显着的趋势，并且在百年至十年时间尺度上存在振荡。通过使用厄尔尼诺和太平洋年代际振荡现象的代理记录对年份进行分类，发现每年登陆的台风数量随着这两个显着振荡的不同阶段而变化，并且这种变化在很大程度上可以根据现代大气数据进行物理解释。这些结果与之前的研究结果一起表明，登陆热带气旋数量的变化很大程度上受到行星尺度大气环流中在不同时间尺度上经历振荡的影响。版权所有 © 2011 英国皇家气象学会
On the basis of Chinese government records, the number of tropical cyclones making landfall along the East China coast during the period 1450–1949 is examined. The annual number of typhoons making landfall in East China during this period is found to possess a positive and statistically significant trend, as well as oscillations on centennial to decadal timescales. By classifying the years using proxy records of the El Niño and Pacific Decadal Oscillation phenomena, the annual number of typhoon landfall is found to vary with the different phases of these two prominent oscillations, and such variations can be explained to a large extent physically based on modern‐day atmospheric data. These results, together with those from previous studies, suggest that variations in the number of landfalling tropical cyclones are largely governed by those in the planetary‐scale atmospheric circulations that go through oscillations on various timescales.
