1961－2010年新疆极端气温时空演变特征研究
Spatiotemporal Variations of Extreme Temperature Events over Xinjiang during 1961 -2010
摘要
Abstract
Spatiotemporal variations of extreme temperature events in Xinjiang have been analyzed based on daily average temperature,daily maximum temperature and daily minimum temperature data from 50 meteorological stations covering the period from 1961 to 2010 using statistical methods and 22 extreme temperature indices commonly used in extreme climate events researches.Daily temperature and mean annual temperature in Xinjiang increased significantly after 1996,minimum temperature in winter and summer rose significantly,and the warming magnitude in winter was greater than in summer.Except for GTmax,GTavg,DTR and TXx,TNx,TXn,TNn,all cold and warm indices are characterized by signifi-cant downward and upward trends respectively in the late 1990s.Overall,the magnitudes of warming tendency of cold indices,low temperature indices,night indices are obviously greater than those of warm indices,high temperature indices and day indices,and they are greater in basins than in mountains.The mutation of trend analysis of extreme cold indices occurred in the mid-and-late 1980s,and that of extreme warm indices occurred in the late 1990s.The warming tendency can be checked obviously no matter with average temperature indicators or changes of extreme temperature indices.Average temperature (GTavg) and maximum temperature (GTmax)during growing season are characterized by an upward trend.The increase of daily average temperature will enhance the intensity of heat wave days (HWDI)and lengthen the growing season.Growing season length is longer in southern Xinjiang than in the northern and eastern Xinjiang,and it is longer in basins than in mountains.关键词
