中国大陆1951-2005年雾与轻雾的长期变化
LONG-TERM VARIATION OF FOG AND MIST IN 1951-2005 IN MAINLAND CHINA
摘要
Abstract
Fog is an important indicator of weather. Long-term trends of fog and mist variation were known by studying meteorological data from 743 surface weather stations in mainland China for the time between 1951 and 2005. For the general geographic distribution of foggy days in mainland China, it is climatologically more in the southeast than in the northwest China and fog appears more in the winter half of the year than in the summer half. Differences are insignificant between decades. Southwest China is the part of the country with the most fog appearance and fog appears on more than 20 days in the year in Sichuan Basin. Serious, persistent heavy fog usually appears in winter and spring over plains in North China and Northeast China. Days with mist are much more frequent in provinces south of the Yangtze River than in those north of it and there is a general increase of misty days after the 1980s. Southwest China is the part of the country where there are most days of mist and Sichuan Basin is misty for more than 100 days in the year.关键词
