| 摘 要： | 利用大气质量的观测资料和气象要素的数据，详细分析了2015年冬季乌鲁木齐市一次重污染天气的主要气象因子和空气质量特征。研究结果表明：在污染过程中，风速的变化趋势：减小-增大-减小（平均风速0.9~2.5 m·s-1）；风向的转化趋势：东南风-东北风-西北风-西南风-东北风；湿度增大-减小-增大；大气混合层厚度的变化趋势：降低-升高-降低。同时，通过SPSS12.0分析了空气污染前后风速，湿度和PM2.5质量浓度的相关性。PM2.5质量浓度与风速呈显著负相关，与湿度呈正相关。风速与PM2.5质量浓度间通过了显著性水平为0.01的相关性检验。表明乌鲁木齐市的气象因子（风速）对当地大气污染影响十分明显。

| Abstract: | Through hourly observation data of the air quality and meteorological factors,the characteristics of air quality and main meteorological factors for a typical air pollution process in Urumqi City,Xinjiang,China in the winter of 2015 were analyzed in detail. In the process of this pollution event, the wind speed was changed in the pattern from decrease to increase to decrease(with the mean wind speed of 0.9-2.5 m·s-1). The wind direction was shifted from southeast to northeast to northwest to southwest and to northeast. The humidity was firstly increased and then decreased and increased again. The thickness of the atmospheric mixed layer was decreased and then increased and then decreased again. In addition, the correlation between wind speed, humidity and PM2.5 mass concentration was also tested. There were a negative correlation between wind speed and PM2.5 mass concentration and a positive correlation between humidity and PM2.5 mass concentration. They all passed the correlation test of 0.01 significant level. It shows that the meteorological factors(wind speed) in Urumqi City have a very significant impact on the local air pollution. |
