| 摘 要： | 文章对呼和浩特市每日24观测频次和每日4观测频次的平均风速、最大风速、风向频率及对应污染风频进行了对比分析,结果表明:两者在平均风速、风向频率及主导风向污染风频方面具有比较一致的变化特征;而在最大风速、最大污染风频、静风污染风频上相差较大,差值分别达2.1 m﹒s-1、1.4%、3.0%。说明两者在定性判断上具有较好的一致性,而在专项研究和定量分析上,每日24观测频次较每日4观测频次风资料更具客观性。

| Abstract: | This paper analyzed on average wind speed, maximum wind speed, wind direction trequency anu corre- sponding pollution wind frequency of 24 observation frequency and 4 observation frequency every day in Hohhot. The results showed that both observation frequencies had consistent variation characteristics in aspects of average wind speed, wind direction frequency and dominant wind direction pollution wind frequency. But both observation frequencies had large differences in aspects of the maximum wind speed, the maximum pollution wind frequency and pollution wind frequency of static wind. The difference was 2.1m/s,1.4%,3.0% respectively. The observation frequencies had better consistency in qualitative judgments. But in special studies and quantitative analysis, the wind data of 24 observation frequency was more objective than the wind data of 4 observation frequency every day. |
