| 摘 要： | 714KaDP型云雾雷达具备30km内的低云和雾监测和预警能力，是专门针对影响机场运行的低云低能见度(两低)天气研制的国内首部毫米波脉冲多普勒雷达。昆明长水机场的试验验证表明，通过提供的云雾基本产品和二次产品，实现了机场两低天气生消演变的有效探测，显著提升了对严重影响空管正常运行的两低天气的监测预警能力。雷达探测发现，714KaDP型云雾雷达对机场及周边低云和雾的生消、演变、移动有着非常敏锐的捕捉能力，特别适合具有明显平流特征的低云和雾(锋面雾、低云平流、辐射雾平流等)的监测和预警，本文介绍了雷达特性、安装位置以及对锋面雾、平流低云和辐射平流混合雾过程的雷达产品分析方法，为提前预警、实时跟踪和云消雾散二次放行决策提供支撑提供了参考。

| Abstract: | This paper briefly introduces the first 714KaDP cloud and fog radar in China and the situation during the experimental verification in kunming changshui airport. The MMW pulse doppler radar is designed specifically for low-visibility weather conditions that affect the operation of civil aviation airports, has a low cloud and fog monitoring and early warning capability within 30km, it can track the low clouds and fog in the airport, and can provide the basic data and other products of cloud and fog. It can provide effective means for the detection of low clouds and foggy weather in the airport, monitoring and early warning ability of the low-visibility weather conditions which seriously affect the normal operation of the air traffic control are significantly improved. A long time radar detection is carried out on areas that are prone to low cloud and fog from upstream in changshui airport.It is found that: the radar has a very keen capture ability on low clouds and fog gengeration, elimination, evolution in airport upstream, is ideally suited for monitoring and early warning low cloud and fog which has obvious characteristics of advection(frontal fog, low cloud advection, radiation fog advection, etc.) Through the different characteristics of low cloud and fog weather process analysis of radar products, weather forecasters can monitor the generation, evolution and elimination of the low cloud and fog how it affect the airport, for the early warning, real-time tracking and evaporating of secondary release decisions provide objective and strong support. It provides an objective and powerful support for early warning, real-time tracking and flight second release. |
