Scientists still don’t entirely understand tornados, which is partially due to their complexity and partly because of how dangerous – and difficult – it is to study them!
A tornado is a violent rotating column of air that reaches from a storm cloud to the ground. Until they pick up dust and debris, tornados can be invisible.
They can reach speeds of up to 480 kilometres an hour and travel up to 150 kilometres though most tornados are much slower than this.
They occur in much of the world, including Australia and New Zealand. In fact, Tasmania just experienced a ‘mini-tornado’ overnight.
Tornados are measured using the Fujita Scale, with F5 being the strongest and F1 the weakest tornado.
