摘要
利用太原市1961年至2000年气温和降水资料,以1971年至2000年各要素的平均值作为基本气候态,统计分析近40a来的气候变化情况,结果表明:40a来太原市气温呈非连续的增温趋势,平川上升率为0.273℃/10a,山区上升率为0.266℃/10a;降水量呈减少趋势,平川减少率为38.07mm/10a,山区减少率为20.75mm/10a。气候变化具有明显的阶段性、突变性和时空不对称性特征。
By using temperature and precipitation data in Taiyuan from the year of 1961 to 2000 and taking the average of essential factors as the basic climate condition from the year 1971 to 2000,the statistical analysis of the climate change situation for 40 years showed that temperature assumes non-continual increase,precipitation assumes the reduced tendency.The climatic change has obvious gradualness,sudden change and spatio-temporal dissymmetrical characteristic.
