Learn about the formation and characteristics of hurricanes, typhoons and tornadoes.
An extratropical cyclone is a storm that derives energy from horizontal temperature differences, which are typical in higher latitudes. A tropical cyclone can become extratropical as it moves toward higher latitudes if its energy source changes from heat released by condensation to differences in temperature between air masses.
Tornadoes often begin as funnel clouds with no associated strong winds at the surface, and not all funnel clouds evolve into tornadoes. Most tornadoes produce strong winds at the surface while the visible funnel is still above the ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.

A typhoon is a type of tropical cyclone that occurs in the Northwest Pacific Ocean, specifically between 100°E and 180°E longitude. It is characterized by a well-defined circular structure with ...
The tornado was rated EF3, but many claim it was a tornado EF4. [citation needed] In November 2009, four tornadoes, rated F1 and F2 reached the town of Posadas (capital of the province of Misiones, Argentina), generating serious damage in the city. Three of the tornadoes affected the airport area, causing damage in Barrio Belén.
[1] [3] Should the hurricane intensify further then it will be rated as a Category 2 hurricane, if it has winds of between 83 and 95 kn (96 and 109 mph; 154 and 176 km/h). [ 1 ] [ 3 ] When a system becomes a Category 3 hurricane with winds of between 96 and 112 kn (110 and 129 mph; 178 and 207 km/h), it is considered to be a major hurricane by ...
