Hurricanes form and intensify over oceanic regions. They require sea-surface temperatures of at least 26°C (80°F) and the influence of the earth’s rotation to initiate a spinning circulation (Coriolis effect). The adjacent map shows the places on earth where these conditions are met for hurricane formation. Hurricanes generally form at the tail of the arrow and typically track following the arrow to its arrowhead. In North America, we call a storm that results from these conditions a hurricane. In other parts of the world, a hurricane is known by other names, including "typhoon" in the Western North Pacific and "tropical cyclone" in the Indian Ocean and the Western South Pacific.
Below is a great infographic depicting how hurricanes form and what a cross section would look like.
