【摘要】 利用1961~2008年云南120个县市逐月雾日资料,分析了云南近50 a雾日的时空变化特征以及对气候变暖的响应.结果表明:①云南雾日具有明显的区域分布.全年及四季雾日有从北到南有增加的趋势.②云南雾日的发生具有明显月际变化特征.云南全年各月都有雾日发生,主要集中于11月、12月和1月,最多的月份是12月.从季节分布来看,云南属典型的冬雾发生区.从不同气候带看,北热带、南亚热带、中亚热带、北亚热带及温带属于典型冬雾发生区,最大月是12月;高原气候带属于典型夏雾发生区,最大月是7月.③近50 a来云南全省四季及年的总变化趋势非常一致,为减少的趋势.6个气候带年雾日频次近50 a总的变化趋势也为减少的趋势.④云南年及四季雾日也存在明显的年代际变化.6个气候带年雾日频次也存在明显的年代际变化.⑤云南各地对气候变暖的响应程度不一致,云南滇中以西以南大部地区雾日频次对气候变暖有着极好的响应,即偏暖时期,雾日频次偏少,而偏冷时期则偏多.更多还原

【Abstract】 Used the monthly fog data(1961—2008) of 120 stations of Yunnan Province,the change characteristics of spatial and temporal distribution in the nearly 50a and its response to Global Warming were analyzed.The results indicated that ①The Yunnan fog has obviously regional distribution.From north to south,the number of annual and four seasons fog increases.②The Yunnan fog has obvious intermonthly change.There is fog happening in each month and happens mainly in November,December or Juanury.Yunnan Province belongs to typical winter fog region.With a view to the climate belts,north tropic zone,south subtropic zone,middle subtropic zone,north subtropic zone and temperate zone belongs to typical winter fog region.The most fog happens in December.Plateau Climate zone belongs to typical summer fog region.The most fog happens in July.③In nearly 50a,the fog change trend of the whole year and four seasons in Yunnan consistently reduced.The trend of six climate zones also reduced.④There are also obviously interdecadal change trend in the annual and the four seasons fog of Yunnan.There are also obviously interdecadal change trend in the six climate zones.⑤The response to climate warming is inconsistent in Yunnan.The fog of most areas of west,south of Yunnan is very excellent relationship with climate warming.When the climate is warmer,the fog may decrease;and vic versa.更多还原
