The first fortnight of June has brought us more typical temperatures at the end of July or even August: there have been numerous days in which wide areas of the southern peninsular have seen the thermometers exceed the 40º line. The problem now is not that heat stays with us throughout the summer, the problem is that it may go more.
Same trend. The heat seems determined to settle on the peninsula, or at least that is what can be detached from models such as those used by the European Center for Middle Term weather forecasts (ECMWF). To understand why, we have to look higher towards the atmosphere.
About 1,500 meters high. According to Explain The physicist, disseminator and researcher at Aemet JJ German in his account Twitterwe have the track in the forecasts on the temperature at height at 850 hectopascales (HPA), which usually refer to an approximate height in the atmosphere of 1,500 meters, the low troposphere zone.
The temperature at this level tends to be related to the temperature that we see at soil level, so it can serve as a reference for how temperatures will evolve in the coming days. According to data shared by German, we not only find a temperature above the climatological average (an anomaly above the 5th Celsius), but the situation will last, with the possibility that this anomaly approaches 10th towards the end of June.
“This is barbarity: far from returning to balance as normal, atmospheric dynamics on the Iberian Peninsula seem to get stuck in an extreme heat generator,” explained in its publication.
Looking at the map. If we focus on The map Prepared by ECMWF, we will also see that heat will remain foreseeably installed on our heads. The forecasts indicate that during the next ten days the almost entire peninsula will be under the influence of temperatures above 20º to 850 HPA, with large areas above the 24th and with some points, the 28th barrier temporarily exceeds.
What’s happening. In a second TweetGerman explained what is happening. According to the expert, a Dana located west of the peninsula and a dorsal (an extension of high pressures associated with an anticyclone) would be responsible for the situation.
A situation that would be seeing aggravated by the low atmospheric movement, thus achieving what German refers as a “static equilibrium point.”
The result: heat and more heat. The result is the intuitive: this warm episode seems to be sentenced to extend over time, at least during the next week. The maximum in a large part of the Peninsular South They could stay above 36º and promptly above 40º.
