摘要:

利用新疆89个气象站1961-2008年的气温资料,分析了新疆近50a气温变化趋势及演变特征。结果表明:新疆各区域年平均气温呈现一致的显著上升趋势,秋、冬季的线性升温趋势最显著;夏、秋季平均气温自20世纪80年代之后呈逐年代上升趋势,尤其是进入21世纪以来增温最明显,其中春季和秋季明显高于夏季,而冬季,北疆和南疆2001-2008年比20世纪90年代气温则分别下降了0.3℃,0.5℃,天山山区则比20世纪90年代高0.3℃;年平均气温、年平均最高气温和年平均最低气温地域变化特征一致,总体表现为增温速率北部大南部小、东部西部大中部小、山区大平原小的特点。年平均最高气温自20世纪80年代呈逐年代上升趋势,而年平均气温从20世纪60年代呈逐年代上升趋势,且其增温速率远远高于年平均最高气温。

Abstract:

Eighty-nine Meteorological stations data from 1961 to 2008 in Xinjiang is used to analyze the trend and variation characteristics of temperature in Xinjiang. The results show that the annual average temperature has consistently and significantly increasing trend, the linear warming trend is the most significant in autumn and winter. The average temperature in spring, summer and autumn after the 1980s presented an upward trend year after year, especially most obvious since the 21st century, and the temperature in spring and summer was significantly higher than in autumn. But the situation in winter was opposite, the winter temperature from 2001 to 2008 dropped 0.3 and 0.5 compared with that in the 1990s in the northern and southern Xinjiang, while increased 0.3 in Tianshan region. The annual average temperature, annual average maximum temperature and annual minimum temperature presented regional consistent variation with warming rate larger in north, eastern and western region and mountain area, smaller in south, central and plain region. Annual average maximum temperature increased from the 1980s, but annual average temperature ascended from the 1960s, and its warming rate was much higher than that of annual average maximum temperature.
