What is the air current?
The air current is the weight of the movable air. They are caused by a number of conditions, but especially pressure and temperature differences. Air currents are shaped and are affected by the Earth's climate and weather and are experienced as wind, both on the Earth's surface, even if they are upstairs, aircraft and flying animals. Air streams also formed the history of the world because since antiquity it has influenced trade and exploration sailboats.
Earth and weather is an extremely complex system of many interconnected components, of which air currents are only one component. Air current is usually created by one of two conditions. The difference in pressure or air temperature between two air masses is by far the most common, but there are other types of air currents such as current current.
When two air masses have different air pressure, air current is formed when air flows from the area of higher pressureLasty of lower pressure. This type of air current is common on or near the Earth's surface and in its vicinity and air pressure streams are the source of most of the planet's surface wind. On the weather map, pressure differences are often marked with a line called isobars. Isobars themselves combine areas of the same atmospheric pressure. When they seem very close to each other, there is a large difference in air pressure between air mass at a relatively short distance, causing air currents to flow very quickly in the form of strong winds.
The temperature current or rising air flow is formed when air mass of different temperatures meet. Cold air is thicker than warm air, and when the cold air mass meets the mass of warmer air, warmer air tends to rise and creates a rising air stream. This interaction between warm and cold air is a source of storms and in extreme cases tornadoes.
current of the jetyp current of air caused by large differences in temperature between airExtexts. Sometimes it is characterized as a river of fast -moving air, which often flows over 200 miles per hour (320 km/h), which gives it its name. Whenever up to four or more different streams can be high above the earth's surface and circle around the world at an altitude of about 4 miles (6.4 km). A few currents, the stream of polar current and the flow of tropical current flows from the west to the east in the northern and southern hemisphere.
