A tropical depression is a tropical cyclone that has maximum sustained surface winds (one-minute average) of 38 mph (33 knots) or less. Tropical Storm. A tropical storm is a tropical cyclone that has maximum sustained surface winds ranging from 39-73 mph (34 to 63 knots).
Why is it called a tropical depression?
Then air at the surface moves toward the lower pressure area, rises, and creates more thunderstorms. Winds in the storm cloud column spin faster and faster, whipping around in a circular motion. When the winds reach between 25 and 38 mph, the storm is called a tropical depression.

Depressions are numbered by the National Hurricane Center. For example, TD8 was the eighth tropical depression to form this season.
Do tropical depressions have names?
Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere.

That year, the United States began using female names for storms. The practice of naming hurricanes solely after women came to an end in 1978 when men’s and women’s names were included in the Eastern North Pacific storm lists. In 1979, male and female names were included in lists for the Atlantic and Gulf of Mexico.
Why do they name hurricanes after females?
The U.S. decided in the early 1950s, that only used female names would be used for tropical systems. It’s not exactly certain why this was the case but some believe that because maritime tradition referred to the ocean as a woman, this may have influenced the decision.
What is cyclone bomb?
Winter storms occasionally strengthen very quickly, bringing strong winds with them. Such intense storms are called “bomb cyclones.” They can be destructive if they move through densely populated areas and drop heavy snow alongside blizzard-like winds.
How do hurricanes form?
Hurricanes form when warm moist air over water begins to rise. The rising air is replaced by cooler air. This process continues to grow large clouds and thunderstorms. These thunderstorms continue to grow and begin to rotate thanks to earth’s Coriolis Effect.
What are hurricanes called in the Indian Ocean?
Called hurricanes when they develop over the North Atlantic, central North Pacific, and eastern North Pacific, these rotating storms are known as cyclones when they form over the South Pacific and Indian Ocean, and typhoons when they develop in the Northwest Pacific.

How did Typhoon Ruby formed?
The genesis of Typhoon Ruby stemmed from the interaction of a trough of low pressure and a westward-propagating tropical wave. This interaction led to the formation of a wind circulation west of Saipan on August 29, 1964. It initially moved west-northwest before curving west.
Where did the tropical cyclones form?
Tropical cyclones form over oceans of the World except in the South Atlantic ocean and in the South eastern Pacific. During the Southern Hemisphere Summer, the intertropical front in these areas moves only a degree or so south of the equator which is not far enough for the coriolis force to become effective.
