近百年北半球陆面降水资料的插补及初步分析

Interpolation and primary analysis of Northern Hemisphere and surface precipitation in the past 100 years

采用 EOFs展开方法插补延长了一个北半球陆面月降水资料 ,并讨论了该资料插补工作的合理性。利用该资料初步分析了近百年北半球陆面降水的基本特点。

WT5BZ]An EOF interpolation scheme is established and continuous sequences of Northern Hemisphere land surface precipitation is obtained in the period of 1900~1996 with its reasonableness discussed.The dataset is helpful to research the large scale climate change,especially for the change of Northern Hemisphere annual/monthly precipitation in the past 100 years.At last,we made a primary analysis of the Northern Hemisphere land surface precipitation with the dataset.
