Finally,after extrapolating the storm based on the ground convergence field with the cross-correlation method,the shape and center of the echo have a very good correspondence between the extrapolation echoes filed and the fact echoes filed.
最后,基于地面辐合场用交叉相关法对风暴进行外推预报,得到的外推回波场和实况回波场在形状、中心强度上都有较好的对应关系。
