What are the properties of the wind, what is the process of the wind, what is the meaning of the wind and what are the names of the wind?

Sometimes we can only feel and enjoy the wind around us or maybe we feel horrified when we see a very strong wind, without any sense of curiosity to know more about the wind. What is the wind? how is the process happening? How is it? even what type? on this occasion will review about, hopefully useful.

UNDERSTANDING THE WIND

Wind is the air that moves due to the rotation of the earth and the difference in air pressure around it. The wind moves from a place of high pressure to low pressure air.

WIND PROCESS AND FACTORS

When heated, the air expands. Expanding air becomes lighter so it rises. If this happens, the air pressure drops because the air decreases. The cold air around it flowed to the low pressure place earlier. The air shrank heavier and descended to the ground. Above the ground the air becomes hot again and rises again. The flow of rising hot air and falling cold air is called convection.

Factors that cause wind to occur include:

  1. Barometric Gradients, i.e. numbers that show the difference in air pressure of two isobars which are 111 km away. The bigger the barometric gradient, the faster the wind blows.
  2. Lokai, the speed of the wind near the equator is faster than wind that is far from the equator.
  3. Location height, the higher the location the stronger the wind is blowing. This is caused by the influence of the frictional force which inhibits the rate of air. On the surface of the earth, mountains, trees and other uneven topography provide great friction forces. The higher a forging, the smaller the frictional force.
  4. Time, the wind moves faster during the day, and vice versa occurs at night.
  5. Actually what we see when the wind blows are light particles such as dust carried by the wind. We can feel the wind because we have a sense of taste, which is the skin, so we can feel it.

WIND PROPERTIES

Some properties of the wind include:

  • Wind causes pressure on the surface that opposes the direction of the wind.
  • The wind speeds up cooling from hot objects.
  • Wind speeds vary from place to place, and from time to time.

WIND VELOCITY

Wind speed is determined by the difference in air pressure between the place of origin and destination of the wind and the resistance of the field in its path.

WIND TYPES:

1. Fixed wind: moves continuously throughout the year in a fixed direction.

Which includes fixed wind:

  • Trade winds: blow from the maximum subtropical region (H) to the minimum equatorial region (L)
  • West winds (westerlies): blow throughout the year from west to east. Blow from the minimum subtropical region to the minimum subpolar region (L), both in the northern hemisphere and even the southern earth
  • Easterlies (polar easterlies): blow throughout the year from east to west. Blow from the polar region to the minimum subpolar area (L)

2. Local wind: only occurs in certain areas.

Example:

  • Sea breeze and land wind: Sea breeze : blowing from sea to land during the daytime. During the day, the land receives heat faster than the sea, so that the sea becomes a maximum air pressure, while the land has a minimum air pressure
  • Land wind: blowing from land to sea at night. At night the land becomes colder faster than the sea. Land becomes maximum air pressure, while sea has minimum air pressure.
  • Mountain winds and valley winds: Mountain breeze: blowing from the slopes of the mountains to the valley at night. At night the air on the mountain cools faster than in the valley. Mountain slopes have maximum air pressure, while valleys have minimum air pressure
  • Valley breeze: blowing from the valley to the mountain slope during the day. The air on the slope is hotter than the valley, because it is first exposed to sunlight. The valley is pressurized
