Comparative analysis and forecasting for foggy weather before and after the relocation of the national basic meteorological station of Qianxi meteorological bureau
The article uses ground observation data from new and old meteorological stations in Qianxi City to analyze the characteristics of heavy fog weather and the physical changes of meteorological elements that form fog at these stations.The results show that the old meteorological station experienced a total of 62 days of heavy fog,with an average of 12 days per year,while the new meteorological station experienced 323 days of heavy fog,with an average of 108 days per year.The heavy fog data after relocation has a clear seasonal distribution characteristics.The fog recorded by the old meteorological station is mainly heavy fog and fog,while the new meteorological station is mainly thick fog and heavy fog.The significant increase in heavy fog days after station relocation may be due to factors such as urban heat island effect,green space humidification and cooling,and altitude changes.Relative humidity,wind speed,cooling amplitude,and the presence of weak precipitation on the day are key indicators for predicting heavy fog weather.
