摘要
从数学上分析了 Doppler 速度(径向速度分量)和水平风场之间的基本关系,利用模拟的Doppler 图像讨论了切变线、涡旋和低空急流等各种典型中尺度系统的 Doppler 速度图像的主要特征。所得结果在短时预报中可用于对实时观测到的 Doppler 图像作定性解释。
The basic relationship between the Doppler velocity(radial velocity component)field andthe horizontal wind field is analyzed mathematically.The major features of Doppler velocity im-age for various typical mesoscale systems,such as shear,lines,vortex and low level jet,are dis-cussed using the simulated Doppler images.The results can be used to interpret qualitively the ob-served Doppler pattern in nowcasting.
