But first, a severe thunderstorm has to form. When they collide (suppose one is coming from the west side and the other is coming from the east side), it creates friction in the air due to the different level of chemistry. A storm quickly develops - there may be rain, thunder and lightning. Localised pockets of air become warmer than their surroundings and begin to rise. But do you really know how a tornado forms into that monstrous swirl of dangerous winds? In the UK, tornadoes form when conditions are ‘unstable’ and showery. We use cookies to give you a better experience. Samaras was … If this violently-rotating column of air reaches the ground a tornado is born.The tornado is often visible because of the presence of a condensation funnel - a funnel-shaped cloud which forms due to the much-reduced pressure within the tornado vortex.Dust and other debris lifted by the intense winds can also help to make the tornado visible.Cold downdraughts eventually wrap around the tornado, cutting off the supply of warm air.
The heat provides energy that drives updrafts - rapidly warm rising air. Ask for details ; Follow Report by Steffanieolmstead 29.10.2019 Log in to add a comment
When wind shear is present during a severe thunderstorm a tornado can form.
Learners who joined this course have also enjoyed these courses. Remember that horizontal vortex formed by the wind shear? Tornadoes are among the most violent storms on … ‘Tornado Alley’, a region of Central USA, is particularly prone to violent tornado outbreaks and is susceptible to large, long-lived tornadoes. Tornado Formation Tornadoes almost always form in strong thunderstorms which develop along what is called a "dry line." They form in a different way from those much larger tornadoes in the US.
When it comes to tornadoes, you’ve seen them, and you’ve seen what they can do. Tornados are created by the clash of two weather fronts (similar to lightning storms). As they develop, we often see funnel shaped clouds extending from the base of the cloud and it is only when these funnel clouds touch the ground that we get a tornado. They are narrow, spinning columns of air that reach the ground from cumulonimbus clouds. Wind shear is the different in wind speed and direction between the different levels of the atmosphere. ‘Tornado Alley’, a region of Central USA, is particularly prone to violent tornado outbreaks and is susceptible to large, long-lived tornadoes.
While a jet stream is moving from west to east with cold, dry air at high speeds in the upper level of the atmosphere, warm and moist air is flowing up from the Gulf of Mexico, moving south to north at slower speeds closer to the surface.

In the spring and summer, warm air from the Gulf of Mexico meets cool air from Canada in this region, and this leads to the formation of powerful storms known as supercells that, if the conditions are right, can spawn tornadoes.Around 30 tornadoes a year are reported in the UK.

That forces a big temperature difference between the storm and the outside environment, so the storm itself is rotating. It has now become a vertical rotating column of air, or as we all know it, a tornado.
Now the updraft within a severe storm can actually turn that horizontal tube on its side, making it a vertical vortex. This is the difference in wind speed and direction with height that create the wind shear. The jet stream is a fast moving tunnel of air about twenty five to thirty five thousand feet up in the atmosphere. How a tornado is formed Although no two tornadoes are the same, they need certain conditions to form - particularly intense or unseasonable heat. A storm forms when you have rising air and condensation releasing heat. The most violent tornadoes are rarely seen anywhere but the USA, Canada and Bangladesh. The jet stream zooms over the Rocky Mountains, pushing cold air over the Plains at speeds of up to 275 mph.
