| 摘 要： | 文章对2005年11月22日至12月2日南通市及邻近地区出现的大范围、长时间连续空气污染过程的天气形势和主要气象要素进行了分析。结果表明：大型稳定性高压伴随而来的稳定层结和小风速，导致大气污染物难于扩散，是这次空气污染过程的主要原因；弱冷空气无法改变大气稳定层结，难于结束空气污染状态；随着强冷空气到来，大气环流形势改变，空气质量改善。

Meteorological Analysis on a Continuous Air Pollution Process in Nantong City |
| |
| Abstract: | During Nov 22,2005 and Dec 2,2005,an air pollution event occurred in NanTong City and near areas. The synoptic situation and key meteorological factors for the pollution event were analyzed. It is concluded that the stable stratification and faint wind in company with large-scope stable high pressure made air pollutants difficult to disperse, the weak cold airflow was too weak to change the stable air stratification, however, as a strong cold airflow came, the atmospheric circulation changed and the air quality was improved. |
