how does air gets generated in the globe,i.e stroms or twisters?

Answer 1

Many tornadoes, including the strongest ones, develop from a special type of thunderstorm known as a supercell. A supercell is a long-lived, rotating thunderstorm 10 to 16 km (6 to 10 mi) in diameter that may last several hours, travel hundreds of miles, and produce several tornadoes. Supercell tornadoes are often produced in sequence, so that what appears to be a very long damage path from one tornado may actually be the result of a new tornado that forms in the area where the previous tornado died. Sometimes, tornado outbreaks occur, and swarms of supercell storms may occur. Each supercell may spawn a tornado or a sequence of tornadoes.

The complete process of tornado formation in supercells is still debated among meteorologists. Scientists generally agree that the first stage in tornado formation is an interaction between the storm updraft and the winds. An updraft is a current of warm, moist air that rises upward through the thunderstorm. The updraft interacts with the winds, which must change with height in favorable ways for the interaction to occur. This interaction causes the updraft to rotate at the middle levels of the atmosphere. The rotating updraft, known as a mesocyclone, stabilizes the thunderstorm and gives it its long-lived supercell characteristics. The next stage is the development of a strong downdraft (a current of cooler air that moves in a downward direction) on the backside of the storm, known as a rear-flank downdraft. It is not clear whether the rear-flank downdraft is induced by rainfall or by pressure forces set up in the storm, although it becomes progressively colder as the rain evaporates into it. This cold air moves downward because it is denser than warm air. The speed of the downdraft increases and the air plunges to the ground, where it fans out at speeds that can exceed 160 km/h (100 mph). The favored location for the development of a tornado is at the area between this rear-flank downdraft and the main storm updraft. However, the details of why a tornado should form there are still not clear.

The same condensation process that creates tornadoes makes visible the generally weaker sea-going tornadoes, called waterspouts. Waterspouts occur most frequently in tropical waters.

Your question is a bit confusing and doesn't completely make sense. There is no real answer your question but, I will try to answer it.

Air gets generated around the globe by the jet stream, which is a river of fast moving air high in the atmosphere. During storms and twisters, air is sucked through an updraft while air falls through a downdraft. Updrafts are generated by atmospheric convection and downdrafts are generated by evaporative cooling or air and rain pulling air towards the ground with it.

Answer 3

Air in motion is called wind.Storms and twisters produce only winds.In fact air is a mixture of many gases like Nitrogen.Oxygen ,Argon,Carbondioxide etc.The formation of these gases and subsequent mixing of these gases in a paticular proportion led to the formation of air, long back-that is when our atmosphere was formed.

Answer 4

This makes no sense.
Tornados are not the creation of air, they are just existing air moving in a certian way.

Answer 5

the wind is from planetary winds that convect above earths surface and storms come from warm fronts meeting cold fronts of cold fronts meeting warm fronts
