A cyclone structures from a huge rainstorm. Inside storm clouds, warm, sticky air ascends, while cool air falls- – alongside downpour or hail. These circumstances can cause turning air flows inside the cloud. Albeit the turning flows begin flat, they can divert vertical and drop down from the cloud- – turning into a cyclone.
What is tornado
A tornado is a violent rotating column of air that develops from thunderstorms. Tornadoes are often associated with severe weather events. A tornado occurs when warm moist air rises rapidly due to instability in the atmosphere, and gains enough momentum to rotate around its own axis. The rotation causes strong winds and heavy rain. Tornadoes can cause extensive damage and loss of lives.
The formation of a tornado begins when a cumulonimbus cloud (a towering convective storm) forms over a supercell thunderstorm. The cloud may have a few small holes where water vapor is escaping. If the updraft becomes stronger than the downdraft, the air inside the cloud rotates faster than the surrounding air. As the air spins faster, it cools and condenses. The cold air then rises while the hot air falls back down toward Earth. This creates a counter-clockwise vortex at the center of the cloud. Once the vortex reaches a certain size, it begins to spin faster and faster until it becomes a tornado. In some cases, the tornado’s rotation continues even after the storm dissipates.
