中文摘要: 通过对我国年、季降水的年代平均距平百分率图的对比分析,计算10年滑动平均距平场相关系数和年代之间平均距平差值t统计量的统计检验。结果表明,我国年、季降水具有较明显的年代际变化趋势。这些结果对于降水的年代气候预测和短期气候预测都具有重要意义。
中文关键词: 年、季降水，年代际变化，统计检验
Abstract:According to the analysis of average decadal anomaly percentage rate for annual and seasonal rainfall,the correlation coefficient of anomaly field with ten-year running mean is calculated, and ,t statistic value of the average anomaly between decades is tested.The result indicates that the rainfalls of annual and seasonal have the tendency of decadal variation.It is highly important for us to predict the decadal climate variation and short term climate variation of rainfall.
