The 0 degree Celsius mark was recorded higher than the highest Swiss mountain, meteorologists said on Monday.
Switzerland is not immune to the heat wave. Worse, the episode that hit all of Europe broke a 27-year record among our Swiss neighbors.
Between Sunday and Monday, the zero-degree isotherm crossed 5000 meters. It was recorded at an altitude of 5184 meters above sea level, the Central Meteorological Department said on Twitter. The 0°C threshold was not measured at such a height during the overnight hours from Sunday to Monday in Switzerland.
An isotherm of 0°C is measured at the Bordeaux radiosonde above 5000 m, i.e. above the summit of Mont Blanc.
By this radiosonde, high-altitude warm air will be over the Alps during the first part of tomorrow. #heatwave #Unclear de Chaleur https://t.co/rsNcHASr2u— MeteoSwiss (@meteosuisse) July 24, 2022
Old record, 5177 meters, dated July 20, 1995. Exceeding the 0°C limit at altitudes of 5000 meters is very rare, even unusual.
