| 摘 要： | 使用逐日观测资料,分析了乌鲁木齐极端天气事件的变化趋势及其与区域气候变暖的可能联系,结果表明:近30年来,乌鲁木齐的低温、大风和雷暴事件减少趋势明显,沙尘暴、大雾等事件呈略减少趋势;暴雨、高温和暴雪事件整体呈略增加的趋势。大雾、大风、低温、高温、雷暴等事件均具有较大的年际变化;暴雨、暴雪、沙尘暴、冰雹等事件的年际变化幅度均较小;各类极端天气事件均存在各自明显的周期性特征。乌鲁木齐年平均气温和高温、低温、沙尘暴等极端事件之间存在较强的相关性,这些与温度相关的极端天气事件的变化与区域气候变暖关系密切。

| Abstract: | Based on the daily weather observation data from 1976 to 2007,the change of extreme weather events and its possible relationship with the climate warming in Urumqi was analyzed by the trend analysis,correlative analysis and wavelet analysis methods.The results show that the low temperature,strong wind and thunderstorm events have a obviously decreasing trend in the last 32 years;sandstorm and heavy fog events have a decreasing trend to different extent,but the torrential rain,heavy snow event and high tempe... |
