Weather forecast. African Anticyclone, a Record for Southern Europe, All Consequences « 3B Meteo

Great heat in Europe! Between the weekend and the start of the new week, the arrival of an African anticyclone is confirmed, bringing a second heat wave to Italy. Indeed, we await a change of scenery driven by large-scale dynamics, which will include the arrival of warm air masses directly from the heart of the African continent.

Heat pump effect. Along with the highly fluctuating jet stream, the 2000s frequently swept southern Europe and brought several heat waves. The UK will act as a heat pump of sorts. The air mass comes directly from the Sahara, so it is very dry and easily ‘heated’ by the general compressional movements of high pressure.

According to the EFI of the Ecmwf, the expected temperatures, while very unusual, are not extreme At the beginning of July, the isobaric surface at 500 hPa is found, in percentage terms, at altitudes (6000m geopotentials) that exceed the statistical distribution, while at certain altitudes. This means that the values ​​of the 500 hPa quota for this period of the year are on record between Spain, North Africa and Sardinia, instead of central-northern Italy which is almost record breaking. It measures how strong the anticyclone is due to warm air coming off North Africa, which is currently nearing a peak of 50°C in Algeria.
