What is the Meaning & Definition of wind

ADSBYGOOGLE


The wind is a weather phenomenon produced by natural causes like rain or snow and is responsible for the movement of air in the troposphere, which is one of the four layers in which is divided the Earth's atmosphere and that fundamental when it comes to the respiration of living beings. The meeting of different pressures in different areas is that produces a current of air or wind.
Basically, the origin of the winds is given by the movements of translation and rotation of the Earth, in both and at the same time, they also cause significant differences in terms of solar radiation, especially that of long-wave which is indirectly absorbed by the atmosphere thanks to the diathermic property that holds air and which makes the only hot sunlight indirectly the atmosphere since the Sun's rays can pass through it but without to warm it up. But the rays of heat (infra-red) reflected by the land and water surfaces are that Yes will achieve air heating, giving rise to the movement of air, i.e. wind.
The uneven heating of the air also causes differences in pressure that can sometimes result in winds.
Types of winds
According to the scale or the dimension of the winds tour, we will have 3 different types of winds: regional, local and planetary.
Planetariums are preeminently generated by movements of the Earth's rotation which originates at the same time the uneven heating of the atmosphere, while the regional as premises will have a similar to the previous origin but will mostly be determined by characteristics that occur in every place in particular. Even more and depending on these types of local or regional winds tend to be more important than the planetary type. These include: sea breezes and land, Valley, mountain breeze breeze, katabatic wind and anabatic.
In tato, it is also possible to meet with native winds of a particular geographical area, for example in Argentina we are
the Pampero, the Zonda and the Sudestada and in Northern Mexico.
Intensity of the wind. Types
When the wind blows well strong for a period short or intermittent it is called as blast, just by the speed with which appears and then disappears. The squalls on the other hand are strong winds, usually lasting one minute. Meanwhile, long-lasting winds have different denominations depending on the force who present, such is the case of: breeze, hurricane and Typhoon.
The wind measurement
There are various instruments that allow to determine the direction in which the wind will blow, among them stands the veleta, a device consisting of a cross that rotates and has prepared the cardinal points; It will be placed in the highest places of the building and for the side that turns we will know in the direction that the wind blows.
The anemometer is another instrument that allows measuring the same thing although it is much more modern than the previous.
The wind, the wind power source
Among the benefits of the wind without a doubt we must mention energy, known formally as the wind power production capacity. Wind energy is then caused by air currents and nowadays such energy is mainly used to produce electricity.
It should be noted that wind power is found in abundance in our nature and it's a renewable resource, i.e. achieved natural and inexhaustible sources such as the wind in the case that concerns us.
Another one of its great advantages is that it is a clean energy, which fortunately contributes in reducing the spread of greenhouse effect gases, for example, is popularly also called the green energy.
Now, among its disadvantages one should quote intermittency presents wind and light ends up hurting the supply of this energy.
On the other hand, the wind holds an important and decisive role as a transport agent, for example in the displacement of the seeds that are planted in the field.
Disadvantages of wind
But not everything is benefit in terms of wind and why it is important to mention that the wind, especially one who holds a speed and remarkable strength can become a serious threat to the integrity of people and also the infrastructure. In cases such as for example the typhoons, the speed can reach more than three hundred kilometers per hour, the wind can be capable of getting a House of rennet and not to mention drag people. Many times these unusual climatic events usually arrive accompanied by strong storms that further complicate the picture.
