| 摘 要： | 利用天山山区具有较好代表性的10个气象台站1960-2009年的历史气候资料,运用线性倾向估计对天山山区近50年来气候变化的主要特征进行了分析。结果表明:近50年来,天山山区能量供给因子中的最高、最低、平均温度温度均呈明显的上升趋势,而日照时数、温度日较差呈明显的下降趋势,云量的变化趋势不明显。空气动力因子风速的下降趋势显著;湿度因子中空气相对湿度略有下降趋势,而水汽压、降水量略有上升趋势。受此影响,近50年天山山区气候总体趋于干向湿发展的趋势,气候朝暖湿方向变化。

| Abstract: | Based on the data obtained from 10 meteorological stations on Tianshan Mountains from 1960-2009,the climatic changes in Tianshan Mountains during recent 50 years were analyzed using the linear trend estimate method. The results revealed that the maximum,minimum and average temperature in Tianshan Mountains had an obvious trend of escalation in recent 50 years,but both the sunshine hours and the mean daily temperature range had an obvious tendency of decline.The change tendency of the cloud cover was not obvious,and the wind speed of air dynamic factor decreased significantly.The trend of relative humidity was slightly downward, whereas the vapor pressure and precipitation were rising slightly.As a result, the climates in Tianshan Mountain areas were getting warmer and more humidity in the past 50 years. |
