Buildup of a Tornado

A tornado is a whirling funnel that starts from what appears to be a tube, which starts from a cloud and which eventually touches the ground. The bottom often has translucent dust, which the strong winds pick up and can be accurately described as a violent rotating column of air. Tornadoes are extremely dangerous and powerful storms. The column of whirling air is connected to a cloud on top that is usually a cumulonimbus cloud and rarely may also be the base of an accumulus cloud. These look like condensation funnels. A waterspout tornado, when it occurs in Africa, occurs in tropical regions that are close to the equator. They are not commonly seen at higheraltitudes.

A few tornadoes have also been noticed in summer, which is September and October; while others have sporadically hit different areas during late summer and occasionally in autumn in February till May.

Tornadoes usually occur in the late afternoon or early evening from 4 p.m. to 7 p.m. and 65% of the tornadoes fall into the category of F0 – F1 on the Fujita Scale. These are categorized as light damage tornadoes. Approximately 25% of the tornadoes can be classified as the F2 storms, which cause considerable damage.
