Abstract

Strong convection is the important weather phenomenon impacting the flight safety, always causes sudden changes of meteorological elements. AMDAR data is of high resolution on spatial and temporal, which can provide vital information for the short-term forecast of strong convection weather in the airport terminal area. This paper extracts the three-dimensional vertical wind profiles and temperature profiles, and produces the wind shear warning analysis diagram in the horizontal and vertical direction. The case studied in this paper is a strong convection at April 2011 in Guangdong Province, AMDAR data, together with multi-source information such as radar, satellite and air sounding is analyzed. The study has found that with high resolution spatial and temporal AMDAR data, wind and temperature disturbance information could reveal the motion of wind shear and turbulence in the airport, so that the unique observational basis for protecting the aircraft's take-off and landing safety is provided.

AMDAR数据的风和温度信息在机场恶劣天气临近预报分析中的应用

强对流是影响飞行安全的重要天气现象，常引起气象要素的突变。AMDAR数据具有高时空分辨率，可为机场候机区强对流天气的短期预报提供重要信息。提取了三维垂直风廓线和温度廓线，生成了水平和垂直方向的风切变预警分析图。本文以2011年4月广东省的一次强对流为例，结合雷达、卫星、空探等多源资料对AMDAR资料进行了分析。研究发现，利用高分辨率时空AMDAR数据，风和温度扰动信息可以揭示机场内风切变和湍流的运动，为保障飞机的起降安全提供了独特的观测依据。
