冬季地面最低温度分析预报服务系统

A Forecasting and Service System of Surface Minimum Temperature

地面最低温度是农业、水利、建筑、交通等部门期望得到的新的预报内容。为此，在分析其气候规律的基础上，对其“天气类型”进行特征分析与划分，建立经验规则，设计岭回归模型，最后建咸具有一定特色的预报服务系统。实践表明，该系统具有较强的实用性和预报能力。

Surface minimum temperature has become a new forecast cement,which is expected by agriculture, irrigation works,architecture, traffic etc. Therefore, based on the surface minimum temperature observations from 1988 to 1992,its climatic features are analysed, the weather patterns are divided, and a ridge regression model is developed.
