An operational platform of refined temperature forecasting was developed based on a meso-scale numerical weather forecast model for Ningxia Province. It can produce, modify and display the hour-to-hour air temperature forecasts for all the stations of Ningxia Province in graphic mode. By means of the regression model of the central meteorological station and the other stations in the same area, the temperature forecast adjustment for all the stations in Ningxia Province can be conducted easily by adjusting temporal curves under the condition of the physical processes relative to temperature forecasting keeping unchanged. It provides a sound support to the system of refined weather forecasting.
