经向型暴雨是形成小浪底—花园口区间特大洪水的惟一雨型。在概括黄淮海地区经向型大暴雨特征的基础上 ,论证了西界 110°E、北界 39°N、东界 116°E、南界 32 .5°N可以作为此类暴雨的可移置范围 ,即包含小浪底—花园口区间在内的气象一致区范围 ,为计算小浪底—花园口区间可能最大暴雨提供依据
The meridional rainstorm is the only rain type that forms the Xiaolangdi-Huayuankou special flood. On the basis of summarizing the characteristics of the meridional heavy rainfall in the Huang-Huai-Hai region, it is demonstrated that the western boundary of 110 ° E, the northern boundary of 39 ° N, the eastern boundary of 116 ° E and the southern boundary of 32.5 ° N can be used as displacements of such heavy rainstorms Range, that is, including Xiaolangdi - Huayuankou range, including the meteorological consistent area, in order to calculate the Xiaolangdi - Huayuankou interval may provide the basis for the maximum rainfall
