the “thermal relief” of the trough actually hides a poisoned gift

  • 25

More than a month later, after a strenuous July and first half of August, much of the country has “normal” (or even slightly cooler than average) temperatures. The long-awaited “thermal relief” has arrived and everything seems to indicate that the thermometers will continue to drop until we are well below normal. We have exchanged the heat for the trough, yes; but that means we’ve traded heat for storms: the ‘cold drops’ season begins.


The W of the polar jet. In the next few hours, polar jet that normally passes between Iceland and the British Isles, it is greatly diverted forming a huge ‘W’ that takes it to pass just above the peninsula. This has some weather events attached to it: a small storm coming through French Brittany and a series of associated fronts bringing in a lot of fresh air.

**Between 4 and 8º below normal***. That fresh air will lower temperatures in the center and north of the country by more than four degrees. The impact on other regions will be uneven, but the drag effect will make the drop noticeable throughout the peninsula. Perhaps Levante is the part that will be least affected by all this and, in some places, temperatures can still be quite high.

Storms, storms and more storms. The entrance of the polar jet will tend to cause storms throughout the country: in the end, the arrival of a cold front in height (that is, the “polar jet”) makes the warm masses that are on the peninsula tend to rise and, in the process, when they cool down, they discharge all the moisture they have accumulated.

For this reason, the worst part will be in the northwest because, as we have been warning for days, the temperature of the Mediterranean “will add more fuel” to this phenomenon of creating storms. It is something to keep in mind because it is more than likely that we will encounter very intense storms and the first major floods of the season are not ruled out.

And then what? As the polar jet returns to its usual position, the situation will normalize on the peninsula and the meteorological preparations for the increasingly long transition from summer to autumn will begin. Of course: especially in the Mediterranean, the ‘cold drop’ season promises to be very strong. We do not know how things will turn out (because these types of storms are meteorological phenomena and prediction models do not go that far), but the situation invites us to be alert.
