降水距平 meaning in Chinese
precipitation anomalies
Examples
- The singular value decomposition analysis between theanomal of monthly mean ozone over kunming and theprecipitation anomaly field in yunnan province
昆明月平均臭氧总量距平与云南地区月平均降水距平场的奇异值分解法分析 - A method is brought forward to identify the dry and flood years for precipitation during september to november in global and large scale areas . the way to test the method is also given
提出了利用降水距平指数和旱涝面积指数对全球及大尺度区域9 - 11月进行旱涝年的划分，以及蒙特卡罗检验方法。 - There is the same characteristics of interannual and interdecadal variation between the first characteristic vecter and corresponding percent of the rainfall anomaly ; the second characteristic vecter which is the most obvious in may has interannual variable characteristics in each month
华北春季及各月降水量第一特征向量和相应时期的降水距平百分率具有相同的年际及年代际变化特征；春季及各月的第二特征向量均存在年际变化特征， 5月最明显。 - With the meteorological and hydrographic data in songhuajiang and nenjiang valley from 1951 to 1995 , using correlation analysis and empirical orthogonal analysis , the rule of the flood and relation between flood and precipitation distribution in this region are discussed . the results show that periodic change of water level is obvious in this region . now water level is in the serious stage from 1980 ' s . there are great relation between the water level of flood period and the precipitation . the unusual precipitation of nenjiang valley has greater impact than that of second songhuajiang valley . at the summer in 1998 , songhuajiang and nenjiang valley encountered the ghastly flood and the reason for that is the anomalous precipitation great exceeding the historic maximum
利用松花江,嫩江流域1951 1995年期间的气象和水文资料,采用相关分析,经验正交分析等方法,讨论了该流域洪涝发生的规律及其与流域内降水分布的关系.文章指出,江流域的水位变化有明显的阶段性,且具有全流域一致的特性,目前正处在80年代以来洪涝较严重的阶段;嫩江流域降水异常偏多对松花江洪涝的影响比第二松花江的作用要大; 1998年夏季,松花江,嫩江流域出现超历史纪录特大洪水的关键原因是嫩江流域6 8月的降水距平百分率远远超过了历史上的的最大值 - The characteristics of precipitation anomalies in summer , previous and simultaneous ssta and preceding winter accumulated snow depth anomalies corresponding to positive and negative phases of 10 - yr mode and 25 - 30 - yr mode are discussed respectively . no matter for 10 - yr mode or for 25 - 30 - yr mode , reverse characteristics corresponding to positive phases and negative phases appear in the above fields . it proves that the decadal variation of sah have a good relation to the decadal variation of other key element of climate system and we can regard sah as a strong signal of the anomalies in the climate system
( 4 )夏季南亚高压东西振荡具有明显的年代际变化特征，本文分别讨论了对应于10年周期态的正位相年和负位相年及25 - 30年周期态的正位相年和负位相年时夏季我国降水距平、前期及同期海温距平及前冬青藏高原积雪距平的分布特征，发现无论是10年周期态还是25 - 30年周期态，对于夏季南亚高压东西振荡的正位相年和负位相年以上各要素场呈现为很好的反位相特征，说明夏季南亚高压的年代际变化与气候系统中其他要素的年代际变化具有很好的关联性，可将南亚高压看作气候系统中大气子系统异常的强信号，通过分析南亚高压的年代际异常可以更直接地研究和预测区域气候异常。
