摘要
在相关普查及分析各因子物理意义的基础上,建立了宁夏不同程度干旱预测的概念模型,结果表明,影响宁夏全区不同程度干旱的大气及海洋强信号并不一定是线性关系,与大气及海洋各系统之间的相互配置,特别是高层与低层之间、中高纬与低纬之间、大气与海洋之间、各大气与海洋系统的强、弱之间及相对位置之间的配置等都有着非常重要的关系。
Based on the related general survey and physical meaning of each factor, the conceptual model for different intensity drought prediction in Ningxia is worked out. The result shows that the atmosphere and oceanic strong signal affecting the drought degree in Ningxia are not a linear relation, but with a mutual disposition between the atmosphere and ocean systems. The disposition between the higher and lower aerosphere, mid-high latitudes and low latitudes, strong and weak intensities and the relative positions of atmosphere and ocean systems is very important.
