We live in Spain for several days at the end of summer much warmer than usualThe field but this anomaly ends, because the polar aircraft will finally bring us what we could consider the beginning of autumn. This news tormented many headlines this morning. When reading it, a mass of Siberian air comes to mind, which comes to destroy the temperature. Of course, the name invites this. However, it should be noted that the term does not give everything that it promises.
IN Hypertual We talked about this with the representative of Aemet Ruben del Kampowho explained to us what a polar aircraft is and what to do with Vagada Is responsible for changing the temperature that comes.
To begin with, it should be noted that technically most often to call the polar aircraft as Reactive currentAlthough both terms are valid and, of course, the Polar Jet sounds more exotic and circulates much better through the networks. With this already clarified, let’s see what exactly, let’s call it, as we call it. Just because The temperature will decrease In some parts of the country, there will also be enough storms, but this is not a sudden arrival of autumn, and even more so since winter.
What is a polar plane?
Polar Jet is the same as streaming current, known in English as Reactive stream. This is a very intense wind circulation that is located in average and high level of the troposphereThe field, that is, halfway to the lowest layer of the atmosphere of the Earth. “Suppose it can be 5000 to 15,000 metersS Hightity, ”says the field, which also tells us about his relationship with aviation.” This flow current is well known to pilots, begins. “When Atlantic surveys from America to Europe, sometimes they put themselves in this current, using it in some way To save fuel“
Returning to meteorology, if we have already seen that this is not a current that will bring us cold polar ice cream, why is it called? “This is called because it is relatively close to polar latitudes“Of course, you must emphasize this” regarding. ” subtropicalThe field then, in order to distinguish them, which is closest to the pole, is called a current in a polar plane. You are closer to the pole than subtropical, but not very close to the pole.
What does the gutter have to come to Spain?
According to the representative of Aemet, the hollow “is a kind of cold air tongue in the middle and high level of the troposphere”, which is formed on the occasion The requirement of the flow in the plane.
“If we imagine that the current at the high levels of the troposphere circulating from west to east, we can think about a direct current that moves, following a parallel planet. But in reality, the current is usually, as a rule, undoubted under different circumstances, sometimes with greater intensity than others. ”
The same thing happens as and when we have a rope, we shake it, and the wave -like are transmitted through the rope.
On the other hand, it is known that the flow of the flow separates a layer of warm air from another cold air. The cold remains in the highest and most warm latitudes in the lowest. And what happens when the separation between the layers is wave -shaped, and we do not have a direct border? These are not borderline deductions. In fact, two things can happen that cold air is transported south or passes north. In the first case, we are talking about VagadaField in the second of dorsal. Therefore, we already know what to do with the polar aircraft to the hollow.
From the field, remember that the hollows are very common. We are not much less, until exceptional weather phenomenon. In fact, when as a result of the specified cavity Cold air weight isolated from a polar aircraft What we know how given is formed. This time this is not so.
So how will this polar plane and this cavity in Spain?
In this case, the hollows will lead to a decrease in cold air in the south, so the temperature in that part of the country, and not in everything, will fall significantly. There will also be storms, “especially in the north -east of the peninsula, in Navarra, Riode, Aragon, Catalonia, the Balearian Islands and areas north of the Valencian community.”
Thus, the polar plane is not a mass of air, which enters directly from the lapia to turn our temperatures. This is a stream of air in the high layers of the troposphere, which occurs closer to poles than to the tropics, and, in this case, the wavy, leading to the gutter, which pulled the air of latitude to the north to the Spanish latitudes. This is not a polar aircraft as such that brings us this autumn part, but a hollow.
Despite this, of course, this is an important change. Little by little we say goodbye to the arrival of phenomena, which are completely normal at this time of the year. Despite how the global climate is changing, we still have a little normality.
