气象条件对晋江城市空气质量的影响

根据2006—2007年晋江市环境监测资料和同期气象资料，对晋江市空气质量状况分布特征、空气污染与气象条件的关系进行分析。结果表明：晋江市区空气质量优良率较高，夏季空气质量最好，春季空气质量最差；海洋性气候是形成晋江市空气质量优良率高的主要原因；空气质量为优的天气形势主要包括冷空气、副热带高压和台风等，空气质量持续为优；空气质量为轻微污染以上的天气形势主要包括SW暖湿气流、入海高压后部偏东气流、弱冷空气影响后期、副热带高压减弱或东退等。

Effects of meteorological conditions on air quality in Jinjiang,Fujian province

According to the environmental monitoring data and meteorological data from 2006 to 2007 in Jinjiang, the relationships among air quality distribution, air pollution and meteorological conditions were analyzed. The results indicate that the excellent and good rates of air quality are most because of maritime climate in Jinjiang. The best air quality appears in summer, the worst one is in spring. Under the cold air, subtropical high pressure and typhoon weather conditions, air quality is usually excellent. Under the SW warm and wet current, easterly current of high pressure rear moving to the sea, last weak cold air influence and subtropical high pressure weakening or moving to east weather conditions, air quality is slight pollution or over slight pollution.
