Tropical Cyclones Portal

A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water vapor contained in the moist air. They are fuelled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms, and polar lows, leading to their classification as 'warm core' storm systems. Tropical cyclones originate in the doldrums near the Equator, approximately 10 degrees away.

The term 'tropical' refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, and their formation in maritime tropical air masses. The term 'cyclone' refers to such storms' cyclonic nature, with anticlockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on its location and intensity, a tropical cyclone can be referred to by names such as 'hurricane', 'typhoon', 'tropical storm', 'cyclonic storm', 'tropical depression', or simply 'cyclone'.

Hurricane Andrew.jpg

Hurricane Andrew was one of the most destructive hurricanes ever to hit the United States. It raged from August 16 to August 28 during the 1992 Atlantic hurricane season, impacting the northwestern Bahamas, southern Florida in the greater Miami area, and south-central Louisiana. Andrew caused $45 billion (2005 US dollars) in damages (mostly in south Florida) and is the second most expensive hurricane in history (behind Katrina of the 2005 season).

Typhoon Yuri eye.jpg

This photograph shows the bowl-shaped eye of Typhoon Yuri in the western Pacific Ocean just west of the Northern Mariana Islands. The eye wall descends almost to the sea surface, a distance of nearly 45,000 feet (13 800 meters). In this case the eye is filled with clouds, but in many cases the sea surface can be seen through the eye. Yuri grew to super typhoon status, packing maximum sustained winds estimated at 165 miles per hour (270 km/h). The storm moved west toward the Philippines before turning northeast into the north Pacific Ocean, thus avoiding any major landmass.
