利用上海地区1900～1999年月降水资料，用Marr波及Morlet小波变换方法分析了上海地区100年来冬、夏季降水时间-频率的多层次时间尺度演变特征及其突变特征。结果表明，其年际及年代际时间尺度的周期变化在时间域中分布很不均匀，具有很强的局部化特征。这些特征可为上海地区短期气候预测服务提供十分重要的参考依据。

Using Marr wavelet and Morlet wavelet transform s,the variations of winter and summer precipitation in Shanghai during one hundr ed years were analysed.Some multi-time-scale and jump features of the variatio ns were discoverd.These features are very important in short-range climate fore cast for Shanghai.The multi-time-scale pattern and the background of Shanghai winter and summer precipitation were given.
