| description | A method for dynamically changing a WRF parameterization scheme combination based on a surface pressure distribution situation includes steps of (S1) constructing a database having a corresponding relation between a historical surface pressure distribution situation and an optimal parameterization scheme combination; and (S2) obtaining an optimal parameterization scheme combination corresponding to the historical surface pressure distribution situation by querying a historical surface pressure distribution situation closest to an actual precipitation forecast surface pressure distribution situation in the database, and running WRF by the optimal parameterization scheme combination corresponding to the historical surface pressure distribution situation, so as to carry out an actual precipitation forecast. The present invention has advantages as follows. The method uses the principle of high correlation between the surface pressure distribution situation and the weather situation to build a database of the surface pressure distribution situation and the optimal parameterization scheme combination, and takes the surface pressure distribution situation at the beginning of forecast as the basis for selecting the optimal parameterization scheme combination, which is able to indirectly reflect the applicability of different parameterization scheme combinations to different weather situations, thus the method provided by the present invention has higher prediction accuracy than the traditional method. |
