What is the Wind

the wind is the movement of air currents relative to the Earth’s surface.

The word wind derives from the Latin ventus which in turn comes from the Indo-European root weWhat does it mean to blow?

Wind, along with atmospheric pressure, are the two most important physical variables that affect climate on Earth.

The wind is produced by the rotational movement of the earth, the insolation effect created by the entry and exit of the sun’s rays through our atmosphere, and the differences in atmospheric pressure caused by hot and cold air.

The wind is important for the Earth and its inhabitants, since it is a natural transport for seeds and birds helping, for example, in the pollination of some plants as an abiotic pollination vector, and in the migration of birds with currents. of winds.

Wind is measured by its speed and direction. The anemometer measures its speed in meters per second or kilometers per second and the vane, an instrument placed on top of a wind rose, indicates the direction or geographic sectors from which the wind comes, such as north, northeast, southwest, this etc

Wind is a renewable energy resource whose energy is called wind. Since ancient times, the wind has been used to produce electricity through windmills. Today, wind energy is generated through wind turbines that are in turn connected to networks for electrical distribution.

types of wind

planetary winds

They are winds that cross the entire length of the Earth influenced by the movements of the Earth’s rotation. They are constant and contain great thermal energy.

Planetary winds affect atmospheric pressure based on air temperatures. When the air is cold, it goes down to the Earth’s surface increasing the atmospheric pressure also called Thermal Anticyclone. When the air is hot it rises into the atmosphere, lowering the atmospheric pressure causing instability, this phenomenon is known as a cyclone or thermal storm.

Planetary winds are classified into:

  • Trade winds: they blow along the equator line from east to west due to the rotational movement of the Earth. They are regular and always move in the same direction.
  • counter trade winds: sun in the strip of the Tropics of Cancer and Capricorn from west to east from the polar circles.
  • circumpolar winds: they are very cold winds and are generated due to the movement of rotation of the Earth and the inclination of its axis.

periodic winds or seasonal winds

Periodic or seasonal winds, also known as monsoons, arise in India, Indochina, Japan, the Gulf of Guinea, northern Australia, and the coasts of Peru.

They are winds from the Indian Ocean that blow for 6 months from the land to the sea and the other 6 months from the sea to the land, causing dry winters and rainy summers.

The El Niño phenomenon and its opposite phase known as La Niña affect these seasonal winds.

regional winds

The regional winds are affected and determined by the distribution of land and seas in the area.

local winds

Local winds affect small areas and territories. The habitual winds that affect these places receive names given by the inhabitants. This custom is called eolionymy. Some of them are, for example:

  • zonda: wind that blows in the eastern Andes of Argentina causing strong and dry winds. They are Föhn or Foehn effect art.
  • north wind: north and northeast direction wind that affects the Mexican coast of the Gulf of Mexico, especially the city of Veracruz in winter.
  • Sudestada: wind that affects Argentina, Uruguay and southern Brazil from December to January.
