Heat is one of the great protagonists of this advanced start of summer, but a tough competition has come out thanks to the periodic storms that continue to condition the peninsular meteorology: hail. A week ago The storms surprised with huge balls, and it seems aimed at repeating the story.
A complex panorama. Summer began with an alternation between warm episodes and atmospheric instability that has given way to An even more complex situation. A “all at once” that may seem disconcerting, but that could actually make quite sense because of some atmospheric dynamics.
Looking at the Mediterranean. A few days ago We pointed out that the Mediterraneanand more specifically the Western Mediterranean, was at a remarkably higher temperature than what would be normal on these dates. Something that can condition the meteorology on the mainland.
Today The predictions They continue to warn of an important risk storms in areas of the west peninsular, especially inside the Valencian Community. As some experts point out, both facts may be more related to what it seems.
From heat to hail. The precedent can be found in the tanizades of the summer of 2022 (some hailstorms who came to leave a deadly victim), Explain in Twitter The physicist and disseminator German JJ. The German himself was a member of the team that last year published An article In the magazine Geophysical Research Letters in which he analyzed the 2022 event and the link between the surface temperature of the Mediterranean and the hailstorms.
The study showed that the appearance of Supercells It was the result of the influence of an “unprecedented” amount of available connective energy. “The intensity of the storm was influenced by the abundant atmospheric energy and the humidity of the warm sea (…). When we exclude the warm sea factor of the simulations, the hail was made smaller,” explained the team in its study.
Probable, not sure. The study was the result of many months of analysis focused on the particular case of 2022. A similar effort would be necessary to confirm the relationship between the present situation of the Mediterranean and the storms we are seeing these days.
“An extremely warm sea does not directly explain very virulent storms. What it does is to enhance that, under favorable atmospheric conditions, they acquire a more aggressive behavior, giving extra and quality energy,” He clarified German.
Where, how and when? Faced with such a convulsa situation, the State Meteorology Agency (Aemet) Maintain various notices For adverse phenomena: while in the west peninsular the predominate notices will be due to high temperatures, in the east it is the notices for rain and storms that colors the map.
Today’s list of notices includes several areas in orange notice by high temperatures, which will be concentrated in the Guadalquivir Valley and surrounding areas: from the Sevillian countryside to the Cazorla region and the safe one the maximums could reach 40º.
