A high-pressure weather system, shaped like the Greek letter Omega, is causing a heatwave across Europe by trapping hot air between two cooler areas. This atmospheric blocking pattern is preventing the usual movement of weather systems. The resulting stagnation is leading to consistently high temperatures. Sunny conditions are further exacerbating the heat. The phenomenon is expected to persist, potentially leading to prolonged high temperatures in affected regions. Authorities are monitoring the situation for potential health and safety impacts related to the heatwave. This ‘Omega’ system is responsible for the current intense heat experienced across the continent.
