Using the Pearson correlation coefficient, absolute and relative error, and scattered point diagram methods, the quality of the combined weather radar wind field (WID v1.0) display products are evaluated. The results show: (1) The product has higher correlation with radiosonde data; there is no systematic difference between the two data sets; and the wind direction correlation is better than the wind speed correlation. (2) As the height rises, the correlation coefficient between the two data sets decreases, and the wind field data availability is higher at altitudes below 500 hPa. (3) The quality of WID v1.0 products has closely relationship with precipitation types, and largescale precipitation is conducive to improve the quality of wind field inversion. The product quality decreases in the situation of nonmeteorological echoes and strong convective weather. (4) The product quality has certain relationship with the complexity of terrain.
