摘要
利用2018—2020年呼和浩特市环境监测站环境监测数据、呼和浩特市气象局激光雷达污染边界层数据以及呼和浩特市区地面观测站温、压、湿、风、降水等数据,对大气边界层高度特性进行较深入系统的研究,定量分析了近3年来呼和浩特市污染天气的变化规律及边界层高度的时间变化规律;总结出呼和浩特市不同等级不同类型的边界层高度阈值;通过典型污染个例的相关性分析得出边界层高度与温度、相对湿度、十米风场的内在关系。通过边界层的特征研究,为分析和预报呼和浩特市污染天气提供一定参考。
Based on the environmental monitoring data of Hohhot Environmental Monitoring Station,the lidar pollution boundary layer data of Hohhot Meteorological Bureau and the data of temperature,pressure,humidity,wind,precipitation and other data of Hohhot urban surface observation station from 2018 to 2020,the height characteristics of the atmospheric boundary layer are studied in depth and systematically,and the variation rules of the polluted weather and the time variation rules of the boundary layer height in Hohhot in the past three years are quantitatively analyzed.Summarize the boundary layer height thresholds of different levels and types in Hohhot;Through the correlation analysis of typical pollution cases,the internal relationship between the boundary layer height and temperature,relative humidity,and 10-meter wind field is obtained.The study of the characteristics of the boundary layer can provide some reference for the analysis and prediction of the polluted weather in Hohhot.
