Learning objective

Students should be able to describe and explain where tropical cyclones (including storms, hurricanes, and typhoons) occur, specifically noting that they are found between 5° and 20° north and south of the Equator, and that they require an ocean surface temperature of at least 27 °C and an ocean depth of at least 60 m.

Read the explanation, check the common trap, then practise with flashcards and questions.

Description

Tropical Cyclone Formation Conditions

Tropical cyclones form between 5° and 20° north and south of the Equator. They require ocean surface temperatures of at least 27 °C and ocean depths of at least 60 meters to develop and strengthen.

  1. a

    Describe where tropical cyclones occur and the ocean conditions needed for their formation.

    Aim for approximately 3 distinct marking points.
