ESTIMATES OF CLIMATE NOISES OF ANNUAL MEAN TEMPERATURES OVER CHINA

In this paper,a design to estimate climate noise of annual mean temperature has been made by means of the minimum interannual variance and effectively independent observations in time series.By using it the climate noises of annual mean surface air temperatures have been estimated based on the data from 1960 to 1991 in this country.The low values of climate noises of annual mean temperatures are found in the southeastern Tibet Plateau,Yunnan,the Sichuan Basin and south of the middle and lower reaches of the Changjiang River Valley.The high values are seen in the northwestern and northeastern China and the rest of the Tibet Plateau.A relatively low value region is in the southern Xinjiang.
