2017-2022年杭州市臭氧浓度与气象因子影响分析
Analysis of the influence of ozone concentration and meteorological factors in Hangzhou from 2017 to 2022
摘要
Abstract
Based on the data of ozone concentration and meteorological factors in Hangzhou from 2017 to 2022,the variation characteristics of ozone pollution in Hangzhou were analyzed,the influences of different meteorological factors on ozone concentration were discussed,and a forecast regression equation between ozone concentration and meteorological factors was established.The results showed that from 2017 to 2022,the ozone concentration in Hangzhou generally showed a fluctuating upward trend,presenting a bimodal change in a year.It increased month by month from January to May,the pollution was the most serious in summer,and the concentration showed a downward trend since September.High temperature and low humidity were important meteorological conditions for the formation of ozone pollution.When the daily maximum temperature was higher than 25℃,the relative humidity was 40％～80％,the daily average wind speed was 1～2 m/s,and the prevailing wind directions were easterly and northerly,high values of ozone concentration were prone to occur.Using the multiple regression analysis method,seasonal forecast regression equations of ozone concentration and meteorological factors were established and their effects were evaluated.The results showed that the forecast equations had good fitting effects and possess predictability.关键词
