中文摘要：

介绍了一种非参数检验—Wilcoxon秩和检验,并将其应用于热带气旋（tropical cyclone,TC）强度预报方法评定.由于在TC强度预报评定中,预报误差的分布是非正态分布,因此无法使用常用的参数检验,必须用非参数检验.结果表明,将Wilcoxon秩和检验应用于TC强度预报方法的评定,有利于更加深入理解TC强度预报方法,提高预报准确性.

英文摘要：

Wilcoxon Signed Rank Test,a non-parametric test,is introduced and applied to the evaluation of tropical cyclone （TC） intensity forecast.The distribution of forecasting error is a significant non-normal one,so those common parametric tests can not be used and this non-parametric test is proposed.As a result,the prediction method of TC intensity can be evaluated by using Wilcoxon Signed Rank Test,which is helpful not only to better understand the forecast method of TC intensity,but also to improve the prediction accuracy of TC intensity.
