| 摘要: |
| 河源是雷电灾害高发区，全市年平均云地闪雷暴日为81天，密集的雷暴天气对高空探测构成极大威胁。为了在雷暴天气雷达顺利追踪目标，本文对东源探空站（2007-2012年），观测时段（07时、19时）雷暴天气过境时的近地面层高空风场资料进行整理、统计、计算和分析，运用风玫瑰图制作软件，绘制出近地面层雷达仰角在（波瓣±6°范围内）方位角的变化频率图。其结果在测试及常规探测中使用良好，对取准取全第一手探测资料有着非常重要的意义和必要性。 |

| Abstract: |
| Heyuan is a high incidence area of lightning disasters. The annual average Thunderstorm Day in the city is 81 days, and the dense thunderstorm weather poses a great threat to the high altitude detection. In order to Thunderstorm Weather Radar successfully tracking target, the Dongyuan sounding station (2007-2012), the observation period (07, 19) thunderstorm weather transit ground high altitude wind field data collation, statistics, calculation and analysis, the use of wind rose map production software, draw near ground layer in radar elevation (lobe + 6 degrees) change of azimuth frequency diagram. The results are well used in the test and routine detection, and it is of great significance and necessity for taking all the first hand detection data. |
