【摘要】：介绍了民航华东气象中心开发的上海机场终端区AMDAR(Aircraft Meteorological Data Relay)资料实时显示系统,简述了系统的基本原理和工作流程;并统计了AMDAR资料的分布特征,对机场出现的雷暴、大风、冰雪等天气进行了实例分析。结果表明:上海机场终端区AMDAR资料实时显示系统直观、实用,有效地提高该资料的使用率;AMDAR资料时空分辨率高,但分布不均匀,资料97.4%集中在00:00—15:00UTC时段和67.3%集中在4km以下的中低空区域;系统能够提供连续的高空风温分布,也能够捕捉到高空中小尺度天气特征,在某些天气过程中能够为短临预报提供良好的客观依据和辅助手段,具有一定的实用价值。
[Abstract]:This paper introduces the real time display system of AMDAR(Aircraft Meteorological Data Relayay data in the terminal area of Shanghai Airport developed by East China Meteorological Center of civil aviation, describes the basic principle and work flow of the system, and statistics the distribution characteristics of AMDAR data, as well as the thunderstorms and strong winds in the airport.Examples of weather such as snow and ice are analyzed.The results show that the real-time display system of AMDAR data in the terminal area of Shanghai Airport is intuitionistic and practical. It can effectively improve the utilization rate of the data and the spatial and temporal resolution of AMDAR data is high, but the distribution is uneven.97.4% of the data are concentrated in the 00:00-15:00UTC period and 67.3% in the middle and low altitude area below 4km. The system can provide continuous upper air temperature distribution and capture the upper and middle scale weather characteristics.In some weather process, it can provide good objective basis and auxiliary means for short-term and impending forecast, and has certain practical value.
