Cyclone vs. Hurricane: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on January 11, 2024
A cyclone is a rotating storm system occurring in various parts of the world, while a hurricane is a specifically named cyclone occurring in the Atlantic and northeastern Pacific.
Key Differences
Cyclones and hurricanes are both types of intense tropical storms with strong winds and heavy rain. A cyclone is a general term used for a weather system in which winds rotate inward to an area of low atmospheric pressure. In contrast, the term hurricane is specifically used for such storms in the Atlantic Ocean and northeastern Pacific Ocean.
The term cyclone is used in various regions, including the Indian Ocean and South Pacific. Hurricanes, on the other hand, refer to the same phenomenon but are specific to the Atlantic and northeastern Pacific regions. The primary difference lies in the location, not in the nature of the storm.
Both cyclones and hurricanes form over warm tropical waters and gain energy from the ocean's warmth. Cyclones in the Southern Hemisphere rotate clockwise, while hurricanes in the Northern Hemisphere rotate counterclockwise. This difference is due to the Coriolis effect.
When a cyclone reaches wind speeds of 74 mph or more, it is classified as a tropical cyclone, typhoon, or hurricane based on its location. Hurricanes are categorized from Category 1 to 5 on the Saffir-Simpson scale, which measures wind speed and potential damage.
The term cyclone encompasses a broader range of storm systems, including tropical cyclones, typhoons, and hurricanes, depending on the region. In contrast, a hurricane is a more specific term used only for strong tropical cyclones in certain geographic areas.

Cyclone and Hurricane Definitions
Cyclone
A system of winds rotating inward to an area of low barometric pressure.
Meteorologists warned of a cyclone developing over the ocean.
Hurricane
A tropical cyclone with winds of 74 miles per hour or higher, typically occurring in the Atlantic.
The hurricane caused unprecedented damage along the coastline.
Cyclone
A large scale air mass rotating around a strong center of low atmospheric pressure.
The cyclone caused extensive flooding in the coastal regions.
Hurricane
An intense tropical weather system with a well-defined circulation.
The hurricane's path was tracked closely by meteorologists.
Cyclone
A natural disaster involving a rotating storm system.
Relief efforts were mobilized after the cyclone hit the area.
Hurricane
A powerful storm characterized by a low-pressure center, spiral arrangement of thunderstorms producing high winds and heavy rain.
Emergency services were on high alert during the hurricane.
Cyclone
A weather phenomenon characterized by heavy rain and strong winds.
The cyclone disrupted air travel and grounded flights.
Hurricane
A severe tropical storm with powerful winds and heavy rain.
Residents boarded up their homes as the hurricane approached.
Cyclone
A violent tropical storm with winds blowing in a circular motion.
Villages were evacuated in anticipation of the approaching cyclone.
Hurricane
A type of tropical cyclone forming in the Atlantic or northeastern Pacific Ocean.
The city was evacuated due to the approaching hurricane.
Cyclone
An atmospheric system characterized by the rapid inward circulation of air masses about a low-pressure center, usually accompanied by stormy, often destructive weather. Cyclones circulate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Hurricane
A severe tropical cyclone having winds greater than 64 knots (74 miles per hour; 119 kilometers per hour), originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean, traveling north, northwest, or northeast from its point of origin, and usually involving heavy rains.
Cyclone
A violent tropical storm, especially one originating in the southwestern Pacific Ocean or Indian Ocean.
FAQs
