Abstract:To explore the relationship between meteorological conditions and topography effect duringcontinuous air pollution process in Bijie City, this paper applies correlation statistics and meteorlogical analysismethods to carry out the analysis on meteorological characteristics. The results show that air pollution in Bijie hasinereased in the last five years, and the number of pollution days in December 2023 is equal to the historicalextreme value. During the continuous pollution process, the correlation coefficients of Bijies AOl to daily rainfall.high temperature, and wind speed are -0.454, 0. 437, and -0.454, respectively, showing a moderate correlation.The pollution process in Bijie is characterized by temperature inversion. At 850 hPa, the forces of north wind andsouth wind are comparable in Bifie region, the thermal low pressure develops on the suface, and the surface windspeed is weak. Influenced by the north-south topography, the lifting and blocking effect of the two sides of thetenain makes the circulation of the ground airflow blocked, so that stable-static weather is more easy to occur inBijie and cause an inerease in the accumulation of pollutants. ''The research results of this paper make clear themeteorological factor characteristics of the continuous air pollution process in Bijie, and could provide ameteorological support basis for taking control measures in advance to improve the ambient air quality.
