摘要
根据典型日的定义,对混合层厚度、风速、降水、湿度的逐时资料进行分析得出各个要素的加权值,最终通过加权值筛选出某段时间的典型日。介绍了用于典型日筛选的Matlab计算程序的使用方法,并以大连市2001年为例论述了典型日筛选过程。在筛选的典型日里,各个气象因子相对其他天都是比较容易造成污染的,结果表明,计算所得的典型日为2001年污染较严重的日子。
Based on the definition of typical day the weighted value through is deduced the data of mixed layer depth, wind speed, precipitation and humidity. At last typical day of period of time is selected. The introduction of Matlab calculating programme is presented, and the selection of typical day is discussed with Dalian in 2001 as an example. In the typical day selected,the meteorologic factors are more easy polluted conditions than other days, The result shows the typical day from the programme is the day of high level pollution in 2001.
