摘要
Abstract
The change causes of climate elements, such as air temperature, precipitation, sunlight and so on were analyzed from 1971 to 2010at Dingtao. The results showed that; (1) air temperature was lower in 1980s, rising fast in 1990s, and higher in 2000s; The annual air temperature rose at a rate of 0.232℃/10a, the daily ail temperature variation decreased, the rise of mean annual lowest air temperature and air temperature in winter contributed significantly to warming climate, and cold air activities also produced significant influence on climate warming; (2)The precipitation in 1980s was lower and the precipitation increased from 2001 to 2010; the precipitation rate increasingly was 13.454mm/10a, an increasing trend of precipitation can be seen. The distribution of flood and drought became heavier from 1993 to 2005, and the anomalies of local precipitation correlated to the El Nino Southern Oscillation (ENSO) events; (3) The annual sunlight duration decreased at 135.21h/10a and more significantly in summer and autumn, which was influenced by precipitation and cloudage in some degree , but not determining the variation trend of the sunlight duration.关键词
