| 摘要: |
| 风廓线仪是新一代大气遥感测风系统。简述了风廓线仪的工作原理,介绍了其应用研究现状,采用澳门和香港风廓线仪资料分析了热带风暴"圆规"影响时的特征,表明在热带风暴的影响下,风向转变非常快,并且在其登陆前后风向发生了明显的转变。从澳门和香港风廓线仪资料的对比及香港风廓线仪资料与探空资料的对比分析可见,风廓线仪测量的数据有较好的一致性,在珠江三角洲地区应用的前景是很广阔的。 |

| Abstract: |
| Wind Profiler is a new generation of remote-sensing system for vertical profiles of horizontal wind speed,direction and vertical wind velocity above ground level.The work principles and research development of wind profiler are introduced in this paper.Based on the data characteristics analyzed from Macao and Hong Kong wind profilers during the time of tropical cyclone "Kompasu",comparisons have been made between wind profilers in Hong Kong and Macao and between the wind profiler data and radiosonde data in Hongkong,which shows that the data of wind profiler systems is quite consistent and wind profilers should have wide application in the Pearl River Delta. |
