Atmospheric Conditions Needed to Create a Hurricane

Conditions for a Hurricane to Form:

There are four conditions that allow a hurricane to exist: low pressure (reinforced by the hurricane) warm temperatures (often in the summer) moist areas(over the ocean) tropical wind patterns(close to the Equator) There are no fronts. A hurricane is its own pressure stsyem.Hurricanes begin when raindrops condense out of warm, moist air. That releases heat, which then makes the air convect. When this happens in a low pressure zone near the equator, it can create an organized system of clouds and storms called a tropical depression. As more moist air is swept up and more rain condenses out, the depression gets stronger, creating a tropical storm. If enough heat is added to the system, it becomes a hurricane with strong winds, an eye, and storm surge.
