| Abstract: | Three sets of 24 and 48 hr forecasts for two synoptic cases have been madewith a shallow-water equation limited-area spectral model and two different-grid-point finite-difference models respectively, together with their statistical verification.Results reveal that the forecasts made with the spectral model are superior to thosemade with the other two models, especially in the case of the genesis of the closed low inNortheast China. The success of the experiments opens good prospects for further appli-cation of the limited-area spectral model and improvement of short-range forecasting. |
