【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。更多还原

【Abstract】 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.更多还原
