| 摘 要： | 首先使用滑动平均的方法,对近58年影响我国的台风频数、强度和年极值强度进行趋势分析,又使用Spearman非参数趋势检验法进行了显著性检验。在此基础上应用基于分形理论的R/S方法对未来的台风频数、强度和年极值强度进行了趋势预测。分析表明,未来影响我国的台风频数、强度、年极值强度都是呈增加趋势的;而且年台风频数和台风强度呈正相关性。

| Abstract: | The moving average is adopted to analyse the trend of the frequencies,strengths and annual extreme strengths of typhoons affecting China in the past 58 years.The Spearman rank correlation is adopted to conduct significance tests.Then we forecast the future trends of frequencies,strengths and annual extreme strengths of typhoons by Rescaled Range Analysis based on fractal theory.The results show that the frequencies,strengths and annual extreme strengths of typhoons affecting China will increase and become stronger.And there is a positive relation between annual frequencies and strengths of typhoons. |
