摘　　要：通过对多普勒天气雷达中VAD技术的深入剖析 ,指出它在揭示测站上空整层风切变、高低空辐合辐散场、含水量分布场中的作用 ,并结合具体实践应用 。Analysis is made of the VAD technique particularly in using Doppler weather radar. The results indicate that it is useful in sounding wind shear, convergence and divergence, and water vapour contribution from bottom to top. Based on these characteristics and real time radar data, some valuable weather information in favor of improving nowcasting accuracy is obtained.
