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'.

The Saffir-Simpson Hurricane Scale is a scale classifying most Western Hemisphere tropical cyclones that exceed the levels of "tropical depression" and "tropical storm" and thereby become hurricanes. The "categories" it divides hurricanes into are distinguished by the intensities of their respective sustained winds. The classifications are intended primarily for use in gauging the likely damage and flooding a hurricane will cause upon landfall. The Saffir-Simpson Hurricane Scale is used only to describe hurricanes forming in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line. Other areas label their tropical cyclones as "cyclones" and "typhoons", and use their own classification schemes.

Did you know…
- … that Hurricane Faith (pictured) was tracked until it was located 600 miles (965 km) from the North Pole?
- …that from the formation of the low that would become Cyclone Katrina and the dissipation of it as Cyclone Victor–Cindy passed 51 days? (track pictured)
- …that since 2011 the Brazilian Navy Hydrographic Center has assigned names to tropical and subtropical systems in the South Atlantic, when they have sustained wind speeds of at least 65 km/h (40 mph)?
- …that, although being the second most intense tropical cyclone ever recorded in the South-West Indian Ocean basin in terms of atmospheric pressure, Cyclone Chris-Damia (pictured) never attained the highest categories in either Météo-France or Saffir–Simpson wind scales?
Tropical cyclone anniversaries
- June 13, 2006 - Tropical Storm Alberto (pictured) made landfall on the Florida Panhandle as a strong tropical storm. Alberto brought heavy rain to the southeastern United States, causing about $500,000 in damage.
- June 14, 1904 - The first storm of the 1904 Atlantic hurricane season (track pictured) made landfall in eastern Cuba, killing at least 87 people.
- June 15, 1991 - Typhoon Yunya (pictured) made landfall in Luzon in the Philippines the same day as Mount Pinatubo made its largest eruption. The rainfall from the typhoon mixed with the volcanic ash, causing severe lahars.
