用典型相关分析作区域性短期气候预测的研究

The Study about Regional Short－Range Climate Forecast with Canonical Correlation Analysis Method

本文引用典型相关分析技术分析了山西夏季降水与若干个因子场的相关关系，指出了影响山西夏季降水的主要因子是副高的活动，在实际预报工作中应该挑选不同时次不同要素的因子场。用该方法建立的模式其预报效果令人满意。

In this paper, we analyzed the relationship between precipitation at Shanxi in summer and some influencing factor fields by using canonical correlation analysis method. The result shows that the main factor that influenced precipitation of Shanxi is subtropical high. We should choose different element fields at different time in our real works. The forecast results of this model were satisfied.
