The possible changes of surface air temperature and precipitation as well as uncertainties of the Global Climate Models(GCMs)-based projection under IS92a GG scenario just considering the greenhouse gases(GHGs)warming effects,IS92a GS scenario with consideration of combined GHGs effects and sulphate radiation effects and the SRES A2 and B2 scenarios in the 21st century had been analyzed.

Anomalous variations of wintertime surface air temperature (WSAT) over the Asian continent and the relationship between WSAT and Asian winter monsoon are first examined by using empirical orthogonal function (EOF) and correlation analysis.

The monthly averaged precipitation and surface air temperature produced by 5 Coupled Ocean-Atmosphere Global Climate Models (AOGCM) are compared to the observation in order to access AOGCMs abilities in simulating regional climate in East Asia.

and the winter surface temperatures in China,we find that there are significant simultaneous correlations between the Eurasian and West Pacific patterns,and the surface temperature anomalies in eastern China,and that there is a significant lag correlation between the West Pacific pattern in December and the surface temperature in eastern China in January.

Based on the observed monthly surface temperature and daily precipitation of 550 stations in China from 1961 to 2000,and the surface temperature and precipitation simulated by 13 IPCC AR4(the fourth assessment report of the intergovernmental panel on climate change) models and their multi-model ensemble(MME) mean,the simulation abilities of the 13 models are evaluated.

The scale of heating and cooling load closely related to temperature variation becomes larger and larger.

The temperature variation characteristics in Southern Xinjiang Basin in recent 45 years were analyzed and the results showed that there was a warm abrupt change of the annual average temperature in 1989.

By means of power-spectrum and wavelet techniques, an analysis was conducted on the temporal frequency structure of temperature variation in Henan Province during the last 50 years, based on the data of 50 stations in Henan Province from 1951 to 2000.

Study on the effect of air temperature changes on hydraulic hoist;

Effects of air temperature change on spring wheat growth at different altitudes in northwest arid area

In order to ensure the concrete construction in winter, various technical measures are adopted for the construction based on the air temperature change therein and good effects are obtained, and then the realization of the project target is guaranteed as well.
