It is any cyclone of non frontal synoptic scale, originated over tropical or subtropical waters, that presents an organized convection and a cyclonic circulation characterized by surface winds.
Being one of the most feared storms existing, tropical cyclones constitute a special class of great wind system in rotation, with unique characteristics of circulation. They cause torrential rains and create serious problems, particularly in the mainland communities near water streams.

Favorable conditions for formation of fronts

Warm ocean waters (at least 80°F or 26.5°C). An atmosphere potentially unstable to moist convection. Thunderstorm activity. Relatively moist layers near the mid-troposphere. A minimum distance of at least 300 mi (500 km) from [...]

Characteristics of a Tropical Cyclone

The surface winds spiral inward cyclonically, becoming almost circular near the center. The cloud and rain patterns are distinctive in each storm. Spiral bands in the outer vortex. Most intense rain and winds [...]

Classification of Tropical Cyclones

Tropical disturbance: light surface winds with indications of cyclonic circulation. Tropical depression: a closed wind circulation and maximum sustained speed of 23-39 MPH (37 to 62 KPH) surface winds. Tropical storm: cyclone [...]

Hurricanes and Typhoons

A hurricane is a very severe tropical cyclone. Characteristics: A diameter of 310 miles (500 km). Winds of 75 MPH (118 KPH) or more. Winds blow drawing a large spiral around a center of [...]

Storm Surge

Rise and onshore surge of seawater as the result of the winds of a storm, and secondarily of the surface pressure drop near the storm’s center. Large crest of water, 50 [...]
