An extreme heat event occurred over Europe from the 22nd to 26th July 2019, peaking on the 25th. Numerous new record maximum temperatures were established in several countries. The following maximum temperatures were recorded on the 25th: While the media has used the term heat wave, there is no single definition for a heat wave. Whether a severe heat event, or heat wave, this study investigates the origin of air over Europe during the heat event from the 22nd to the 6th and whether high surface temperatures were caused primarily by adiabatic subsidence, rather than the horizontal advection of warm/hot transported northward from North Africa using re‐analysis data, atmospheric soundings from two locations and five day trajectories.

2019年7月22日至26日，欧洲极端高温：是由沉降还是平流引起的？

2019年7月22日至26日在欧洲发生了极端高温事件，在25日达到顶峰。许多国家建立了许多新的最高温度记录。在25日记录了以下最高温度：尽管介质使用了热波一词，但对热波没有统一的定义。无论是严重的热事件还是热波，本研究调查了22至6日热事件期间欧洲上空的空气起源，以及高表面温度是否主要是由绝热沉降引起的，而不是由热/热的水平对流引起的使用重新分析数据，来自两个地点和五天轨迹的大气探测，从北非向北运输。
