The area around the Taihu Lake is quick and sensitive in response to climate elements changes,such as temperature and precipitation with regard to complex and variable climate,special geographical location and landform morphology.Therefore the study in this area is profound and significant for explaining the local special climate changes and laying the foundations for the research about the impact of urbanization on the climate changes around the Taihu Lake area in the future.Based on the daily mean temperature and daily precipitation data of 9 meteorological stations around the Taihu Lake area from 1971 to 2010,the methods of linear regression,EOF analysis,Morlet wavelets analysis and Mann-Kendall Test were used in this paper to analyze the spatial and temporal pattern and characteristics of climate changes.The results are as follows:(1)During the period 1971-2010,the air temperature around the Taihu Lake area has been increasing in general,and the precipitation distribution had an increasing tendency in the northern part of the area and a reducing tendency in the southern part.There is a spatial difference of seasonal heating rate in the area around the Taihu lake area,the air temperature in the northwest area increased significantly in spring and summer,while there was a significantly heating rate in autumn and winter in the southeast area.Besides,there was a completely opposite spatial-distribution in heating rate around the year of 1990.In the whole area the precipitation was increasing generally in winter,the spatial precipitation distribution differs widely in spring and summer.(2)The annual mean temperature fluctuated significantly with an interval of 16 years or 17 years,and fluctuated with the intervals of 6 years and 26 years in the small scale of the whole area around the Taihu Lake area.The annual precipitation in the area fluctuated significantly with interval of 15 years or 16 years and 24 years.Whereas,there were some differences in intensity of the annual mean temperature fluctuation and the annual precipitation fluctuation in terms of different regions.(3)During the period 1992-1993,there was an abrupt climate change from low temperature to high temperature for all stations in this area.
