3Fe2 Whirlwind – Whirlwind model

The formation of whirlwind

When the local temperature is high, air near the ground expands and rises (low air density) to a higher level where the temperature is low (high air density), and air circulation is formed.  As a result, the air from surrounding high pressure flows to the central low pressure together with the impact of the Earth’s rotation to form a rotating air vortex.
