A maximum wind gust speed of 79.3 kn was measured on 2 August 2011 at the Esenboğa International Airport (International Air Transport Association [IATA] code: ESB), which is located in Ankara, the capital of Turkey. This value is the highest maximum wind gust speed value measured at this airport over the last 60 years. At the time of this meteorological event, a thunderstorm with heavy rain (+TSRA) occurred, which reduced the runway visibility to 150 m. Total precipitation of 21.8 mm was measured during a 20-min period, and part of the apron was submerged. A multicellular severe convective storm (MSCS) caused this influential event. The purpose of this study is to investigate the meteorological conditions underlying this MSCS event. Synoptic and sounding reanalysis products obtained with the Weather Research and Forecasting (WRF) model (four nested domains were established with horizontal resolution of 27, 9, 3, and 1 km), in addition to satellite, radar, sounding, aviation routine weather report (METAR), selected aviation special weather report (SPECI), and automated weather observing system (AWOS) (on a minute basis) data obtained from the Turkish State Meteorological Service (TSMS), were analysed. During MSCS transition, the maximum radar-measured reflectivity value was 61.0 dBZ. Based on Stokes’ theorem, maximum runway divergence and convergence values of 15.0 × 10^–3 and 19.3 × 10^–3 s⁻¹, respectively, were calculated. As a result, it was found that compared to the low convective available potential energy (CAPE) value of 978.9 J kg⁻¹, the 0- to 6-km above-ground-level (AGL) deep layer shear was high, at approximately 40 kn.

2011 年 8 月 2 日，在位于土耳其首都安卡拉的埃森博阿国际机场（国际航空运输协会 [IATA] 代码：ESB）测得的最大阵风速度为 79.3 节。该值是过去 60 年来在该机场测得的最高最大阵风速度值。本次气象事件发生时，发生大雨雷暴（+TSRA），跑道能见度降至150 m。在 20 分钟内测得的总降水量为 21.8 毫米，部分停机坪被淹没。多细胞强对流风暴 (MSCS) 导致了这一有影响的事件。本研究的目的是调查此次 MSCS 事件背后的气象条件。天气研究与预报 (WRF) 模型（建立四个嵌套域，水平分辨率为 27、9、3 和 1 公里）获得的天气和测深再分析产品，以及卫星、雷达、探空、航空常规天气报告(METAR)、选定的航空特殊天气报告 (SPECI) 和自动天气观测系统 (AWOS)（以分钟为单位）从土耳其国家气象局 (TSMS) 获得的数据进行了分析。在MSCS过渡期间，雷达测量的最大反射率为61.0 dBZ。基于斯托克斯定理，最大跑道发散和收敛值为 15.0 × 10 和自动天气观测系统（AWOS）（以分钟为基础）从土耳其国家气象局（TSMS）获得的数据进行了分析。在MSCS过渡期间，雷达测量的最大反射率为61.0 dBZ。基于斯托克斯定理，最大跑道发散和收敛值为 15.0 × 10 和自动天气观测系统（AWOS）（以分钟为基础）从土耳其国家气象局（TSMS）获得的数据进行了分析。在MSCS过渡期间，雷达测量的最大反射率为61.0 dBZ。基于斯托克斯定理，最大跑道发散和收敛值为 15.0 × 10分别计算了^–3和19.3 × 10 ^–3  s ^-1。结果发现，与 978.9 J kg ^-1的低对流可用势能 (CAPE) 值相比，地平面以上 0 至 6 公里 (AGL) 深层剪切较高，约为40 节。
