| 摘 要： | 利用2000-2006年无锡站的城市日供电量资料、城市空气污染指数和地面观测资料对无锡地区的空气污染指数、气温日较差、平均相对湿度、降水量和降水频次周末效应进行了分析.结果发现,空气污染指数和各气象要素的周末效应受到日供电量的影响,同时各气象要素自身和空气污染指数之间有较好的相关性,它们的周末效应相互影响.同时对周末效应的分析采用分季节讨论的方法,避免了由于全年平均对结果的不好影响.采用了不同的周末效应指数定义,即定义某一影响因子的周末效应指数为气象要素周末WEEKENDS(周六和周日)的平均值减去WEEKDAYS(周一到周五)的平均值.

| Abstract: | In this paper the weekend effect of air pollution index, diurnal temperature range, mean relative humidity, precipitation and fallout frequency in the Wuxi region are analyzed by use of the daily power supply amount data, API data and surface weather observation data from 2000-2006. Analysis results of the Wuxi station shows that the weekend effect of API and meteorological elements is influenced by the daily power supply amount. And API and meteorological elements have good correlation. We not only analyze weekend effect by using yearly averaged values, which may underestimate the amplitude of the weekend effect in the meteorological elements, but also try to detect their seasonal characteristics. In this paper weekend effect index is defined as the average meteorological element for Saturday and Sunday minus the average value for Monday through Friday. |
