TORNADO
1.Rising air is the first ingredient needed for a tornado to develop.
Any storm is formed when condensation occurs, the byproducts of the clouds.
2. Condensation releases heat,
And heat becomes the energy that drives huge upward drafts of air.
The more condensation and the bigger the storm clouds grow, the more powerful updrafts become.
In supercells, this rising air-mass is particularly strong
3. As the air climbs, it can change direction and start to move quickly.
4. Finally, at the storm’s base, if there is a lot of moisture, a huge cloud base develops, giving the tornado something to feed off later, if it gets that far.
5.When all these things are in place, a vortex can develop enclosed by storm.
6. and forming a wide, tall tube of spinning air that then gets pulled upwards,
we call this a mesocyclone.
7.outside, cool, dry, sinking air starts to wrap around the back of this mesocyclone, forming what’s known as a rear flank downdraft
8. This unusual scenario creates a stark temperature difference between the air inside the mesocyclone, and the air outside, building up a level of instability that allows a tornado to thrive.
9. Then, the mesocyclone’s lower part becomes tighter, increasing the speed of the wind. If, and that’s a big if, this funnel of air moves down, into that large, moist cloud base at the bottom of the parent storm,
10. It sucks it in and turns it into a rotation wall of cloud, forming a link between the storm that created it and the Earth.
11. The second that tube of spinning cloud touches the ground,
It becomes a TORNADO.
