  • EOF
    EOF分解,用ncdisp命令可以看到HadISST_sst.nc是1870年1月至最近的全球SST数据,按比例截取北太平洋(20N-80N 130E-90W)1971年1月至1990年12月240个月份的SST数据进行经验正交函数(Empirical Othorgnal Function)分解,简记为EOF分解,得到该区域该时段的海温时空特征。(EOF decomposition, with ncdisp command can see HadISST_sst.nc is January 1870 to the recent global SST data, in proportion to the interception of the North Pacific (20N-80N 130E-90W) 1971 年 1 月 至 1990 年 12 月 240 month SST data, empirical orthogonal function (Empirical Othorgnal Function) decomposition, abbreviated as EOF decomposition to obtain spatial and temporal characteristics of sea surface temperature in the region of the period.)
