| Abstract: | Numerical forecasting is one of the main methods in ambient air quality forecasting service across China. Several factors such as forecasting model products, basic input data, external technical support, subjective and objective deviation and forecasting hit probability will affect the results of numerical forecasting in varying degrees. This paper discussed the influence of these factors on the results of numerical model forecasting and targeted improvement methods, in order to reduce forecasting deviation and then improve the overall effect and quality of routine forecasting,finally provide technical reference for local cities and regions. |
