Interannual Variations of Winter Temperature in China and Their Relationship with the Atmospheric Circulation and Sea Surface Temperature
我国冬季气温的年际变化及其与大气环流和海温异常的关系

By using the monthly mean temperature in 160 stations of China, the interannual component of winter mean (November to March of the next year) temperature in China, whose period is shorter than eight years, is studied with the empirical orthogonal function (EOF) analysis for the period 1951/1952-1999/2000. Two distinguished modes are clarified, with the first EOF mode depicting a pan-China temperature variation and the second EOF mode describing a temperature oscillation between northern and southern parts o...
