Analyses on Air Temperature and Its Abrupt Change over Qinghai-Xizang Plateau in Modern Age

Xiao Ma

Abstract

Monthly mean temperature, monthly mean maximumand minimum temperature of 84 stations in Qinghai\|Xizang Plateau from beginning to 2001 are analyzed. The results show that standardized annual mean temperature increase at rate 0.21～0.42/10a; the rate of minimum temperature increase by 1～3 times maximum temperature. Daily Temperature Range (DTR) decrease significantly at rate -0.08～-0.51/10a. The abrupt changes of temperature can be found mostly in 1980′s, in which Northern Hemisphere mean temperature increased significantly after 1988. The abrupt change of mean temperature began in Chaidamu(1973), maximum, minimum temperature and DTR begin in east Qinghai\|Xizang Plateau, Chaidamu and south Qinghai\|Xizang Plateau respectively.
