tropical cyclone
MediumTechnical/Formal
Definition
Meaning
A rapidly rotating storm system characterized by a low-pressure center, strong winds, and heavy rain, typically forming over warm tropical oceans.
Refers to a large-scale meteorological phenomenon that can cause widespread damage, influence climate patterns, and is a key subject in atmospheric science and disaster management.
Linguistics
Semantic Notes
Often used interchangeably with 'hurricane' or 'typhoon' based on geographic location; specifically denotes systems in tropical regions with sustained wind speeds above a certain threshold.
Dialectal Variation
British vs American Usage
Differences

FAQ
Frequently Asked Questions
A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation.
Tropical cyclones are large-scale systems hundreds of kilometres wide, forming over oceans, while tornadoes are much smaller, intense vortices typically occurring over land.
They are most common in tropical regions such as the Atlantic Ocean (hurricanes), Northwest Pacific (typhoons), and South Pacific and Indian Ocean (cyclones).
Key factors include warm ocean waters (above 26.5°C), atmospheric moisture, low wind shear, and a pre-existing weather disturbance.
