| 摘 要： | 利用厦门城市1980～2000年21年地面资料和探空资料，对能见度和雾演变特征及其物理成因进行分析，结果表明：厦门城市夏季能见度明显好于冬季，这可能与冬夏盛行风向不同，输送排放污染源地不同以及不同季节天气气候条件相关。厦门城市冬季和夏季能见度呈下降趋势，尤以夏季为突出，轻雾以上的频数也日益增加，其重要因素是城市的热岛效应。厦门城市能见度虽然明显好于污染较为严重的北京，但冬季厦门城市能见度与北京呈反位相演变趋势。夏季厦门城市能见度有着明显的日间变化，这与夏季海陆风日变化的垂直环流圈有密切关系。

| Abstract: | Based on visibility and fog data from 1980 to 2000, the characters of fog and visibility, and the evolvement rules are studied. The result shows that visibility in summer is better than that in Winter. This may be caused by different prevailing wind, transportation of pollutants, and different weather condition between winter and summer. There is a downtrend of Xiamen's visibility. Days of light fog are increasing. Visibility in Xiamen is much better than that in Beijing where is serious pollution. Xiamen's visibility has distinctly daily variations, it is related with sea land breeze in summer. |
