| 摘 要： | 本文取全省25个代表站1960－1999年5－6月的降水资料和北半球500hPa，北太平洋海温的月平均资料为素材，首先标定降水的异常指数和异常年例，其次应用小波分析，自相关，功率谱和周期分析等方法揭示降水的演变规律。最后分析异常降水的500hPa环流背景和海温特征，所得结果可为我省的短期气候预测提供线索。

| Abstract: | The precipitation data during May-June at 25 representative meteorologicalstations in Fujian Province, 500 hPa height data in northern hemisphere and monthly mean sea temperature in North Pacific from 1960 to 1999 were selected. First, the anomalous index and anomalous years of precipitation were defined. Next, statistical methods of wavelet analysis, autocorrelation analysis, power-spectrum analysis, periodic analysis were used to reveal variable regularity of precipitation. Finally, the features of 500 hPa circulation and sea temperature of anomalous pricipitation were analyzed. The results may provide help for the short-term climate variation prediction of precipitation in Fujian Province during rainy season. |
