Study on Time-Spacial Changes and Sudden Characteristic of Winter Mongolia High
冬季蒙古高压的时空变化和突变特征研究

Based on the 155-year global monthly mean sea surface pressure data (during January 1850~December 2004) from Hadley centre,the periodic changing and sudden characteristic of Winter Mongolia High are studied. Firstly,the winter SLP distribution in Asia-North Pacific is analyzed by the EOF method. Secondly,main cycle sequences of Winter Mongolia High are reconstructed by the method of Singular Spectrum Analysis,especially,the interdecadal periodic change is analyzed by the point,and finally,the sudden point i...
