The big vapor flux area had very close relationship with heavy precipitationarea.
高水汽通量区与强降水落区密切相关。
2
Yi river Basin is located in high precipitationarea and the river system is asymmetric.
沂河流域地处降雨高值区，水系呈不对称特征。
3
The precipitationarea has a good relationships with low level positive vorticity, water vapor, pressure energy, moist enthalpy, potential vorticity etc.
