Abstract
Using the rainfall data of 103 observational stations in Xinjiang from Jun.to Aug.in 1961—2006,the rainfall field of Xinjiang in summer is divided objectively into 4 regions by rotated empirical orthogonal function(REOF) method.The results indicated: the long-term trends of summer rainfall in 4 areas were identical,but their intensities were discrepant,moreover the distinct feature of catastrophe and period existed remarkably in 4 regions.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
