In meteorology, a tropical cyclone (also referred to as a hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone depending on strength and geographical context) is a storm system characterized by a low pressure center and numerous thunderstorms which generally forms in the tropics. While they can be highly destructive, tropical cyclones are an important part of the atmospheric circulation system, which moves heat from the equatorial region toward the higher latitudes. They develop over large bodies of warm water, and lose their strength if they move over land. This is the reason coastal regions can receive significant damage from a tropical cyclone, while inland regions are relatively safe from receiving strong winds.

Saffir-Simpson Hurricane Scale
TD	TS	1	2	3	4	5

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.

Tropical cyclone anniversaries

November 29, 2004 - Cyclone Agni (pictured) reached its peak strength in the Arabian Sea and was named by the India Meteorological Department. The previous day the storm was very close to the equator, with part of its circulation in both hemispheres.
November 28, 2005 - Tropical Storm Delta became extratropical as it passed to the north of the Canary Islands. It was responsible for more than $350 million of damage in the islands.
November 27, 1982 - Typhoon Pamela briefly peaked as a 185 km/h (115 mph) typhoon as it passed through the Marshall Islands. Pamela caused damage throughout several Pacific Islands.
November 26, 1974 - Typhoon Irma reached its peak strength with 215 km/h (135 mph) winds to the east of the Philippines.
November 25, 1987 - Typhoon Nina (pictured) hit southern Luzon with sustained winds of 265 km/h (165 mph). Nina killed over 500 people in the Philippines and its storm surge destroyed fourteen villages.
