摘要
利用南昌新一代多普勒天气雷达获取的2002～2005年37次（共计614组样本）完整风廓线资料，与同期探空风廓线进行相关分析。结果表明：探空风廓线与雷达风廓线之间具有比较好的相关性。风向相关系数R≥0．6次数占总数78％，其中R≥0．8次数占总数60％。风速相关系数R≥0．6次数占总数81％，其中R≥0．8次数占总数57％。随着高度增加，探空风向与雷达风向的相关度明显降低，风速的相关变化不大。
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.
