Interview – With unpredictable signals, the wind is fascinating us as much as it frightens us. Mysterious mechanical degradation with the climayologist.
In connection with AIR, one of the four elements that make up our universe, the wind is the breath that makes all things pointless. He creates a dream, cleanses the sky and thunderstorms. But it can also become one of our worst nightmares, cleaning everything in its own way. Climadologist Philippi Dobinsky, CNRS Research Director Dynetology Dinety Dynetology Dinetology, reveals some of its tips. Where does our wind charm come?
MEDIME FIGARO A number – Why does the wind make it so much?
Philip Dobinsky. – What makes him magic that he is invisible, no priority? We can neither imagine him or caught him. There is nothing around the tree, and suddenly his leaves are moving, he has a mysterious party. The move refreshes us, turns the beautiful clouds on top of our heads … But this wonderful has a double face. It dreams you, but it’s very scared. A cyclone, this car of thousands of kilometers, capable of tearing us from the ground or roofs, destroys everything in its own way, has extremely attractive.
Should we talk about the wind or wind?
The physical mechanism that creates the wind is universal. It moves, air current that leads to the difference between pressure. In case there is excess air. High pressure area. It will move to go and fill space where the pressure is less, it is as simple as it is clear. So the wind is the air that moves, it has only one definition. The higher the pressure difference between the two places, the greater the wind speed. But if the physical mechanism is always the same, the ingredients of the recipe can range from one place to another. Some of the gaps between high and low pressure for Mistra are due to the help of the Alps and Ron’s valley. This wind whose name is derived from Latin Magister (:Master), dominates and shapes the provisional landscape. It conveys a collective imagination, it is the wind that drives you crazy. Autan, Tramontane, Sirocco … Therefore the idea of the soil in multiple.
How is the “pages air flows” of this planet circulating?
It depends on two factors. First, the country is a realm. Thus, the equator exposed to more vertical solar radiation than poles, they accumulate more warmth from them, which leads to high pressure and low pressure. The wind is the mechanism that transports and redistributes this unnecessary energy from equator to poles. But he doesn’t do it in a straight line, it would be very clear. The earth turns, the wind trajectory is deviated. This explains that we have Western winds in our latest.
Have we hit all mysteries of the wind?
In no way. For example, we measure the vertical wind very bad, the one who causes the movements we feel on the planes when we are greeting the famous “air slot.” Whoever decides whether thunderstorm will be violent or not. Thus, we need to better measure it better understand what is happening during such violent meteorological phenomena. It is also difficult to measure wind on top of the ocean, which includes 70% of the Earth’s surface, as it is difficult to deploy observation tools. However, the wind contributes to the evaporation and cooling of the ocean, which plays an important role in the formation of cyclones. These exchanges between the ocean and the atmosphere require new observation tools to better assess the impact of winds between the sea currents or the thermal exchange between the sea and the atmosphere. And, as such, the satellites are a great revolution.
The wind refreshing us has a double face. Dreams but is also very cowardly

About this
They allow us to measure the wind where we didn’t do it, or very little, and it was difficult to install tools. For example, too at height. Aeolus’s mission (called Greek Eole’s Latin form, wind God), which began in 2018. This allows you to understand wind speed and behavior in the upper atmosphere, the theoretical models of consideration and in the digital prediction of time integration. Thus, the weather’s role in improving weather forecasts in the climate system.
With climate change, cyclones, storms and tornadoes will be more dangerous.
They will not be more but they will be more intense. A tropical cyclone, which is a heat machine depends on the size of the top layers of the ocean and the temperature. The greater the gap, the more powerful, violent phenomenon. However, climate change tends to freeze high layers and heat low layers. The shock between these two air masses can only be stronger. In our width, on the other hand, as the poles warm more than the equator, the difference in temperature becomes less mark than between these two areas. Therefore, the winds must weaken and the fronts, therefore the fall of intensity. But at the moment, they are more predictions than the observations. Aeolus-2 new mission must be launched in the near future to allow us to further explain to all the secrets of OLOLE.
