What are the global winds and what are the types of winds? Wind is a type of climatic elements that exist in the globe, and it performs many different works in its different functions. Climate reflects the climate fluctuations that occur in the atmosphere. Temperature is one of the most important weather and climate factors that affect other climate elements because it plays a major role in the formation of winds. In the following lines of this article, we will talk about the types of winds and their intensity.
What are global winds?
They are large air masses formed as a result of the Earth’s rotation and the force of the Earth’s surface heating by the Sun. These masses are named according to the direction in which they flow. For example, global winds blow from areas of high atmospheric pressure to areas of low pressure over large areas of the globe in the same direction. All year round, therefore they are called global or planetary winds.
What are the types of wind
The types of winds differ according to the regions in which they blow and the time they blow, below we list their types
It is stationary and high pressure, its air masses blowing from northern and southern regions to tropical low pressure areas, mostly found in the easterly surface wind pattern.
It blows from subtropical regions of high pressure to subarctic regions of low pressure, which lie precisely between the tropics and the Arctic Circle or Antarctica.--
Its origin is the north and south poles of the globe and it consists of dry and cold air masses located at latitudes, so there is a great distance between them and the equator and occurs specifically in the polar regions at latitudes 60-90 degrees.-
It is one of the types of global winds that originate in the eastern regions and move westward as a result of the earth’s rotation. It is located between latitudes 0-30, because the air gets warmer as it rises to the equator and becomes colder as it moves away from it.
It is named by this name, because it blows in the summer and winter seasons, and its air masses are characterized by changing directions, as happens between the two tropical regions, each of which has summer monsoons and winter monsoons.
These winds result from the diversity of areas of atmospheric pressure, which leads to the formation of winds over small areas, so that it blows quickly over those areas and quickly disappears. This is due to the natural factors present in its region such as the topography. season, but they blow at separate times.
A device used to measure wind speed
An anemometer is used to measure wind speed, and this device has been in use since 1450 AD. There are several different types, each with its own distinctive characteristics. This device depends on the principle of its operation on several different principles, depending on the type of device and the purpose for which it is used specifically , and among the most prominent species
- The traditional device that has been used since ancient times to measure wind intensity and speed.
- A device that measures the speed of sound waves.
- And devices that rely on shining laser beams on small particles in the air to measure the intensity of their impact.
