Establishment and Test of Ozone Concentration Prediction Equation in Huaian Area
Based on the analysis of the relationship between near-surface ozone concentration and related meteorological factors in Huaian area from 2016 to 2019,a prediction model of ozone concentration was established,and the prediction model was tested by using the data of 2020.The results showed that the meteorological conditions favorable to high ozone concentration were suitable surface pressure and upper geopotable height,high surface and upper temperature,suitable surface relative humidity and upper dew point temperature difference,small wind speed and specific wind direction between surface and upper level,suitable total radiation irradiance,low total and low cloud cover and long sunshine time.The high concentration ozone potential index(HOPI)and wind direction index(WDI)were defined,and combined with the surface and upper level meteorological factors,the ozone concentration prediction equation with multiple indexes was established.The prediction equation of ozone concentration was tested by using the data of 2020,and it was found that the correlation coefficient between the forecast value and the actual value was 0.83,indicating that the prediction equation had good fitting effect and forecastability.
