| 摘 要： | 研究采用滇西北(德钦站、香格里拉站、贡山站、维西站、丽江站、泸水站、大理站)七个站点1961~2010年每日降水量、日均温以及最高和最低气温数据,通过STARDEX Diagnostic Extremes Indices Software得到各个站点的57个极端气候指数,运用散点图分析近50年内滇西北极端气候的变化趋势,并用Matlab进行突变检验.结果表明:滇西北地区近50年来气温总体呈上升趋势,年日较差降低;异常极端高温连续日数增加,"暖冬"现象更突出,霜冻日数减少,生长期延长;区域极端降水不均衡,连续干、湿日数增加;降水集中的季节性更明显.

| Abstract: | Using mean daily temperature and precipitation, daily maximum and minimum temperature data from 7 stations of Northwest Yunnan in recent 50 years, the extreme climate change of Northwest Yunnan was analysed. The results showed that on one hand, the temperature was raised and the abnormal extreme high temperature days, continuous drought days and continuous rain days were increased. On the other hand,frost days were reduced. |
