On 9 August 2019, a devastating tornado hit southwestern Luxembourg and caused widespread damage and many injuries. The atmospheric environment, in which the tornado occurred, was characterised by a moderate latent instability, very strong vertical wind shear and high storm-relative helicity. The radar images show typical characteristics of a tornadic supercell, that is, a hook echo and a well-defined velocity couplet. To assess the risk of tornadoes associated with supercells in the future, the Luxembourgish weather service (MeteoLux) elaborated an ingredients-based forecast concept.

2019 年 8 月 9 日在卢森堡的破坏性龙卷风:实现更好的运营预测

2019 年 8 月 9 日,一场毁灭性的龙卷风袭击了卢森堡西南部,造成大面积破坏和多人受伤。发生龙卷风的大气环境具有中等潜在不稳定性、非常强的垂直风切变和高风暴相对螺旋度的特点。雷达图像显示了龙卷风超单体的典型特征,即钩状回波和明确定义的速度耦合。为了评估未来与超级单体相关的龙卷风风险,卢森堡气象局 (MeteoLux) 制定了基于成分的预报概念。
