根据天气形势、本地气象要素等分析易于产生泉州沿海区域性污染的气象条件，重点从干湿条件、相对湿度及无雨日数等与湿度相关的要素方面探讨泉州沿海区域性污染的干湿污染特点。结果表明：泉州沿海区域性空气污染产生的天气系统主要有地面高压（高压底部、后部或高压脊）、地面倒槽、低涡锋面和锋前暖区等形势；地面气象要素多为升温降压、日风向及风速存在海陆风变换、夜晨有雾霾现象；相对湿度在70％-80％时，易造成区域性空气污染。

Based on the weather situation and the local meteorological elements and so on,the meteorological con-ditions leading to the regional air pollution in Quanzhou were analyzed.Wet and dry pollution characteristics in the coastal zone of Quanzhou were discussed in terms of dry and wet conditions,relative humidity and the non-rainy days and so on.The results indicate that regional air pollution is generated in the coast of Quanzhou under those main weather systems,such as the ground high pressure(the bottom,rear or ridge of high pressure),the ground in-verted trough,low vortex front,warm zones before the front and so on.For the ground meteorological elements, temperature increases and air pressure decreases;the direction and speed of the daily sea and breeze transforms each other;it has fog and haze at night or in the morning.When the relative humidity reaches 70%-80%,it is easi-ly lead to the regional air pollution.
