Abstract: | Over 40 a observed temperature data in 172 stations in China and historical proxy data were analyzed. Evidence suggested that
during 1980–1994, the warmest year appeared first in southeastern part of the Qinghai-Xizang (Tibet) Plateau (henceforth SETP)
and then gradually spread northwards and eastwards to eastern China. The climatic change on century time scale in recent 600
a shows 3 relatively warm and clod stages in China. Each warm and cold stage appeared first in Tibet Plateau (henceforth TP)
and then in the Qilian Mountains, then in the eastern parts of China. The warm and cold stages in TP were 10–60 a earlier
than in the eastern China. The facts show that TP is a pilot region of climatic fluctuation in China on the time scale shorter
than 103a. |
