       3 simultaneous #Heatdome|s over N-America, the tropical N-Atlantic, and the W-Mediterranean. Shown is the geopotential, which is (near) record high in all 3 areas. The strong upper anticyclones favor large-scale, strong subsidence and adiabatic heating.#Heat #Heatwave #Weather

       The backward #Trajectories for #Sicily clearly show how the air is trapped in the broad circulation of the anticyclone, descending as if in a swirl and heating. #Heatwave #Heatdome

       The heat is therefore "home-made" and not advective. This form of heat waves seems to have increased, due to persistent weather systems. They can be much more intense than the heat dominated by air mass advection. Those that can combine both processes are particularly dramatic.
