【摘要】 利用相关统计法分析2006—2008年厦门市地面气象要素对空气污染指数变化的影响规律。结果表明:风速、气温、降水、相对湿度和水汽压对空气污染指数均有显著负效应作用,气压起显著正效应作用;风向影响较为复杂,NNW—N—E—ESE风起正效应作用,SE—S—W风起负效应作用,厦门风向总体不利空气质量提高,全年仅夏季盛行SE—S—W风。API指数与风向、气温、降水、气压、相对湿度和水汽压的季节变化规律有高相关性。API指数与气象要素中的水汽压关系最相关,其次是气压。更多还原

【Abstract】 The effects of surface meteorological elements on air pollution index(API) were analyzed by statistical analysis from 2006 to 2008.The results indicate that wind speed,air temperature,precipitation,relative humidity and vapor pressure are significantly negative correlations with API.The relationship between air pressure and API is positive.The effects of wind direction on API are complex.NNW-N-E-ES wind direction with API is a positive correlation,while SE-S-W wind direction is negative.In general,wind direction is not benefit for improving air quality in Xiamen for only in summer SE-S-W wind direction is prevailing.There are significant correlations between API and the seasonal variations of meteorological factors including wind direction,air temperature,precipitation,air pressure,relative humidity and vapor pressure.Of them,vapor pressure with API is the most correlative,the next is air pressure.更多还原
