Differences between Cyclone and Hurricane
Contents
Cyclone vs. Hurricane
The terms cyclone and hurricane both refer to the same weather phenomenon: the tropical cyclone.[1] A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters.[1] The specific term used—hurricane or cyclone—depends on where the storm originates.
All[1] tropical cyclones form over large bodies of warm water and derive their energy from the evaporation of that water. For[2][3] a storm to be classified as a hurricane or a cyclone, its maximum sustained wind speeds must reach at least 74 miles per hour. Storms[4][1] with lower wind speeds are classified as tropical depressions or tropical storms.

Terminology and Regional Differences
The name given to a tropical cyclone is determined by the regional meteorological center responsible for that area.
Hurricanes are tropical cyclones that form in the North Atlantic Ocean, the northeastern Pacific Ocean, and the central North Pacific Ocean. The Atlantic hurricane season officially runs from June 1 to November 30. The[1] Saffir-Simpson Hurricane Wind Scale is used to categorize hurricanes from Category 1 (74-95 mph winds) to Category 5 (winds greater than 156 mph).
[5]Cyclones are tropical cyclones that form in the South Pacific and Indian Oceans. In the Indian Ocean, these storms can also be referred to as "severe cyclonic storms". The[2] timing of the cyclone season varies between the basins within this region. For example, the North Indian Ocean has two peaks, from April to June and again from September to December. Different intensity scales are used in these regions, such as the Australian tropical cyclone intensity scale, which has categories from 1 to 5.
Another term for the same weather event is typhoon, which is used for tropical cyclones that form in the Northwest Pacific Ocean.
Regardless of the name, these storms can cause significant damage from high winds, heavy rain, and storm surges.
