Heat dome: what is it?

“From the weekend, even warmer air will rise from the south, leading to the establishment of a heat dome”, explains Meteo Europe.

A “heat dome” is a recent expression that is widely used during the summer period in weather reports. This is a term popularized for the general public to characterize a phenomenon of “bell”, “cover”, by the high atmospheric pressures which therefore form a dome.

Due to the appearance of a fairly large and static anticyclone on the territory, a heat dome will soon form and will trap the warm air. This trapped air, which tries to escape, will then heat up by compressing itself towards the ground. Disturbances such as rain and wind will be blocked by this barrier, as well as clouds.

High temperatures (between 39° and 40°) are expected in certain regions of Europe this Saturday, especially in the south-east and south-west of Europe. “This weekend, the high temperatures are increasing, in particular in the southern half of the country.
