After being hit by several devastating heat waves in recent years, Europe experienced an exceptionally hot June in 2019 again. This June is the hottest one on record over Central Europe both in a monthly‐mean sense and in terms of the number of extremely hot days. The above‐normal hot condition is caused by an anomalous long‐lasting anticyclone in the upper troposphere, which advects warm air from the Sahel and Mediterranean region and enhances incoming solar radiation and surface turbulent fluxes. The anomalous anticyclone results from an unusually‐intensified British‐Baikal Corridor (BBC) pattern and a synoptic Rossby wave breaking (RWB) event over Europe. Three sub‐monthly heat waves are observed in the month. The first two are associated with the BBC pattern, and the third is related to the combination of the previous BBC pattern activity and the RWB event.

2019年6月中欧创纪录的热浪

在近几年遭受几次毁灭性热浪袭击后，欧洲在2019年再次经历了异常炎热的六月。从平均月度和极端炎热的天数来看，6月是中欧有记录以来最热的一年。高于正常水平的高温是由于对流层上空长期存在的反气旋异常引起的，该气旋将来自萨赫勒和地中海地区的暖空气平流，并增强了太阳辐射和地表湍流通量。反旋风异常是由异常增强的英国-贝加尔湖走廊（BBC）模式和欧洲上空的台风罗斯比波浪破碎（RWB）事件引起的。本月观测到三个月以下的热浪。前两个与BBC模式相关，
