1981-2015年中国95°E以东区域性暴雨过程时、空分布特征OA北大核心CSCDCSTPCD
Characteristics of temporal and spatial distribution of regional rainstorm processes to the east of 95°E in China during 1981-2015
基于1981-2015年中国逐日降水量加密观测资料和NCEP/NCAR再分析资料,采用主、客观相结合的方法,以天气过程为单元建立了中国95°E以东地区及其6个子区的区域性暴雨过程个例谱,进一步使用小波功率谱、9点二项式平滑及离差平方和聚类等方法剖析了中国95°E以东区域性暴雨过程的时、空分布统计特征.结果表明:(1)中国95°E以东区域性暴雨过程平均年总次数接近30次;其中,江淮流域是出现区域性暴雨过程最多的子区,平均为19次/a;其次为华南和西…查看全部>>
The events of the regional rainstorm processes (RRP) to the east of 95°E in China over 1981-2015 are constructed based on intensive daily observations of precipitation in China and NCEP/NCAR reanalysis data by means of subjective and objective analyses.Temporal and spatial characteristic distribution of RRP in China are further investigated using the methods of wavelet power spectrum,nine-point binomial smoothing and Ward cluster analysis.The main conclusion…查看全部>>
