三江平原地区开、封江时间与当地气候变化的关系

Relations of Opening-River and Closing-River Time with the Climate Change in the Three-River Plain

使用MaxHat小波和Haar小波变换分析了三江平原地区开江和封江时间与当地前期气候变化的关系,结果表明:3月份温度与开江时间有良好的相关,8月份的温度和降水、10月份气温以及9-10月的降水与封江时间有较好的相关。

Mexican Hat wavelet and Haar wavelet transform are used to analyze relations of openingriver and closingriver time with preutous climate changes in the ThreeRiver Plain.Results show that the temperature of March is significantly to the time of openingriver,and the temperature and rainfall of August,the temperature of October,and the rainfall of SeptemberOctober,are related to the time of closingriver.
