摘要:

用中国602个台站1961年1月~2003年12月的地面观测大雾、气温、相对湿度资料,采用线性回归分析、相关分析和对比分析等方法,分析了43年来中国地区大雾日数与气温、湿度变化的关系。结果表明:大雾日数偏少 (多) 与气温偏高 (低)、相对湿度偏小 (大) 存在一定的对应关系。这种对应关系较好的区域是中国的西部、北部、川东、云贵高原和东南丘陵地区。

关键词: 中国, 气候, 大雾

Abstract:

Using foggy days and mean temperature and relative humidity of 602 stations from January to December in the period 1961-2003 in China, the relationship between variations of foggy days and temperature and its possible reason for 43 years were analyzed by regression, correlation and contrastive analysis methods. The results show that the higher (lower) the mean temperature and relative humidity, the lower (higher) corresponding to the less (more) foggy days, the relationship is best in the western, northern, eastern Sichuan, the Yunnan-Guizhou Plateau, and southeast highland in China. This induces a decrease in relative humidity when the climate becomes warmer, and eventually brings about a decrease in foggy days in China.

Key words: China, climate, fog
