| 摘 要： | 利用2014-2016年承德市环境监测站和气象站的数据，分析了气象条件对承德市O3-8h浓度的影响，探讨了臭氧污染气象条件的预报方法。结果表明：4-7月是承德市O3-8h浓度较高的月份，O3浓度的日变化特征为午后浓度高而夜间浓度低；O3污染的天气形势为500 hPa受高压脊和偏西气流影响，850 hPa有强暖平流和20℃以上的高温，地面受低压前部和高压后部之间的偏南气流影响；有利于O3-8h出现高浓度的气象因子为日平均气温大于23℃、日最高气温大于28℃、日平均海平面气压995-1007 hPa、日平均水汽压18-28 hPa、偏南风大于1 m·s-1。利用气象因子综合评分建立臭氧污染指数，与O3-8h浓度的相关系数高达0.7553，说明臭氧污染指数能较好地预报臭氧污染天气。

| Abstract: | Based on the data from the environmental monitoring stations and weather stations in Chengde from 2014-2016,the influence of meteorological conditions on the concentration of O3-8h was analyzed.The forecasting method of meteorological conditions for O3 pollution was discussed.The results show that the concentration of O3-8h from April to July is higher than that in the other months in Chengde.The diurnal variation of O3 concentration is characterized by the high concentration in the afternoon and the low one at night.When the O3 pollution happens,it is affected together by the high-pressure ridge and the west airflow at 500 hPa,the strong warm advection and high temperatures above 20℃ at 850 hPa,and the southerly airflow between the low-pressure front and the high-pressure rear at sea level pressure field.The meteorological factors that are favorable to increase the O3 concentration are as follows:the daily mean temperature is higher than 23℃;the daily maximum temperature is higher than 28℃;daily mean sea level pressure is 995-1007 hPa;the daily average water vapor pressure is 18-28 hPa;and southerly wind is greater than 1 m·s-1.Based on the comprehensive score of meteorological factors,the O3 pollution index is established.The correlation coefficient between O3 pollution index and O3 concentration is 0.7553,which indicates that the O3 pollution index can be used to predict the ozone pollution weather. |
