How Do Tornadoes Form Step By Step (2023)

1. How Do Tornadoes Form? | NOAA SciJinks – All About Weather

The Short Answer: A tornado forms from a large thunderstorm. Inside thunderclouds, warm, humid air rises, while cool air falls--along with rain or hail.
These are the most violent storms on Earth. Can we forecast them even better?

Sunshine heats the ground which in turn heats the air near ground level. Localised pockets of air become warmer than their surroundings and begin to rise.
This Met Office video explains the phases in the formation of a tornado.

How are tornadoes formed? · Stage 1 - Storm development. Sunshine heats the ground which in turn heats the air near ground level. · Stage 2 - Storm organisation.
While no two tornadoes are the same, there are certain conditions that are required for their formation. A tornado's development can be described by a sequence of distinct phases.

On average, about 800 tornadoes occur in the United States each year. They can appear and disappear in moments, and key details about their formation are unknown. These factors make the research to understand and predict tornado occurrence extremely difficult. This video segment adapted from NOVA describes the challenges of studying tornadoes and shows how computer simulations are helping researchers observe what they can't possibly see in a real storm.
