| 摘 要： | 根据昆明市1980~2005年的逐月气象资料,应用线性倾向估计法、距平值法分析了降雨量和气温的年内年际变化特征,并采用Mann-kendall方法对降雨量和气温变化趋势进行了检验分析。结果表明,1980~2005年昆明市降雨量呈上升趋势,但上升趋势不明显;平均气温呈明显的上升趋势;降雨量和平均气温年内变化呈两头小中间大的分布,季节分布明显。Mann-Kendall趋势检验表明,昆明市不同季节降雨量变化与年变化趋势不完全一致,春季、冬季和全年明显上升,秋季明显下降;不同季节平均气温变化与年变化趋势完全一致,均为明显上升趋势。

| Abstract: | Based on the monthly meteorological data collected from Kunming weather stations during 1980-2005,the change characters of annual and inter-annual precipitation and temperature were analyzed by linearity trend estimation and annual temperature anomaly.Moreover,Mann-Kendall technique was applied to detect the change trend of precipitation and temperature.The results demonstrated that the precipitation showed an increasing trend,but the trend was not obvious and the mean temperature showed a clear upward tren... |
