最优子集回归在青藏高原冬季降水、气温预报中的应用及改进

APPLICATION AND IMPROVEMENT OF OPTIMUM SUBSET REGRESSION PREDICTION METHOD IN WINTER'S PRECIPITATION AND TEMPERATURE FORECAST OVER QINGHAI-XIZANG PLATEAU

最优子集回归预测方法在天气预报等领域得到了越来越广泛的应用 ,方法本身没有涉及到图形处理。我们对方法、原理及过程进行深入细致的研究后 ,重新编写了程序的头部、中部、尾部语句及子过程调用函数 ,经多次调试试验 ,实现了入口资料调用灵活、多变、计算模拟结果屏幕绘图显示等 ,提高了预测方法的整体实用性和预测信息的可视化程度。检验得知 :该方法对青藏高原冬季降水、气温的定性、定量预报均具有较高的预报精度。

The optimum subset regression prediction method is used widely in weather forecasting fields,but it doesn′t mention the graphic processing.By studying carefully the method principle and procedure,re-write the head,body and the end statement,also including the sub-program's function.After an amount of debug and test,it gets a compute results,improving the whole practice of prediction and visual level in prediction information.After testing,the method has a high precision in winter′s precipitation quality and quantity of temperature forecast over Qinghai-Xizang plateau.
