Belgium is preparing to experience temperatures close to 40 °: how long will this heat wave last?

“This new peak within this episode is explained by the presence of a heat of heat installed on Western Europealways decrypts Tristan AMM. Nevertheless, in the columns of the Parisian. However, It is a large. Meanwhile, powerful high pressure that comes to block the air in a low layer and which prevents any disturbance be able to penetrate and sweep the air. In addition, this dome will gradually warm the air by compression phenomenon.“

Heat in Belgium: MRI emits an orange warning for the main part of the territory from midnight

This heat wave concerns a large part of Europe. However, with around twenty cities in Italy, including Rome and Venice, placed on alert. Therefore, In Portugal. Moreover, two thirds of the country were on orange alert on Sunday, with 42 ° C provided for in Lisbon and belgium preparing experience temperatures close a maximum risk of fire. Meanwhile, In Spain. Meanwhile, the heat peak arrived from this Sunday with a mercury beyond 40 ° C on a large part of the territory.

In Belgium, we are rushing towards an official heat wave – Belgium preparing experience temperatures close

And in Belgium? Furthermore, We will also approach 40 degrees, potentially, according to the forecasts of MRI. Nevertheless, “”On Monday. Furthermore, the heat will increase with maximums of 31 to 34 degrees in most regions, but close to 27 degrees by the sea. The risk is limited but a downstream downpour may burst. mainly in the south of the countryit is said on the side of MRI. Tuesday will be a particularly hot day with maximum around 29 degrees at the coast. from 30 to 33 degrees in the Ardennes and 34 to 36 degrees elsewhere, or even very locally a little more. Time will remain sunny.

Heat belgium preparing experience temperatures close wave: this is why the SNCB will remove around twenty trains on Monday. Tuesday

But most of the heat is expected for Wednesday. It is an evolution compared to the first forecasts which provided a drop in mercury on Tuesday evening. “”On Wednesday. the hot weather should still concern us with maximums which could be greater than 35 degrees over a large part of the country and locally reaching values ​​of around 37 or 38 ° C. In the coastal region, temperatures should not, however, exceed 26 degrees. Time will remain quite sunny. but the atmosphere will become more unstable from the west at the end of the day and the following night with risk of some thunderstorms“, We learn.

How AI becomes the ally of meteorologists

Thunderstorms are therefore to be expected. but it is always difficult to know where they will fall, despite belgium preparing experience temperatures close current technologies. Additionally, But will we soon be able to predict with precision where the next storm will fall? Artificial intelligence may well change the situation in terms of weather forecasts. If classic physical models remain the basis of modern weather, a new approach emerges: that of automatic learning.

“Traditional models simulate the atmosphere by solving physical equationsexplains Fabian Debal, principal meteorologist at MRI. These simulations require a power of colossal calculation, and certain phenomena, such as tornadoes or turbulence, are still poorly modeled. The AI ​​is completely happening in physics: it learns from a large number of past situations to predict the. probable evolution of a current atmospheric state.“

Weather: Google launches an artificial intelligence program that promises to predict time in unparalleled way “

This original. operation has several advantages. “”First, AI is much less greedy in computer resources. Then, it spontaneously corrects certain biases belgium preparing experience temperatures close of physical models. If a model always gives two degrees too much. the AI ​​will compensate it automatically without us having to understand the cause“He explains.

But everything is not perfect. AI does not “understand” what it does. “”She does not know what a cold front is, or that he cannot rain without a cloud. Result: it can generate incoherent forecasts. This is why researchers are considering hybridization between physical models and AI, the two approaches nourishing each other.“

As for seasonal forecasts, they require a probabilistic approach, known as “set”, still little developed in AI. “”But nothing technically prevents it from getting there. Artificial intelligence will therefore not replace the physics of soon, but it is already becoming a precious ally“, He concludes.
