By using 37 CINRAD complete wind profile data and sounding data in 2002—2005, the correlation analysis is made. The result shows that there is a good relativity between radar wind profile data and sounding data. Frequency of correlation coefficient in wind direction R≥0.6 is 78%, R≥0.8 is 60%. Frequency of correlation coefficient in wind velocity R≥0.6 is 81%, R≥0.8 is 57%. With the high increment, the relativity in wind direction is lower, but that in wind velocity don′t change obviously.
