What it is Filled
A rotating storm system with a low-pressure centre, organised thunderstorms and strong winds that forms over warm tropical or subtropical oceans; sufficiently intense tropical cyclones are called hurricanes in the Atlantic and eastern Pacific or typhoons in the western Pacific, while terminology in the Indian Ocean and South Pacific follows regional classifications; classified by sustained wind speed and tracked by regional meteorological centres, these systems bring wind, storm surge and flooding rain.
Why it exists Filled
Let an agent explain tropical cyclones and their classification, relay forecasts, warnings and preparedness guidance from meteorological and emergency authorities, route people in danger to official warnings and emergency services first, and separate tropical cyclones from other storms.
Distinguishing features Filled
- Warm-core low over warm ocean
- Organised rotation with an eye
- Wind, surge and rain hazards
- Regional naming and scales
What robots and AI may and may not do Filled
Must not
- Issue its own forecasts or advise people to ignore official warnings.
- Spread unverified track or intensity claims.
- Tell people a storm has passed or is safe before the authorities do.
- Send people into flooded areas or storm surge zones.
Only with a human decision
- Ordering or calling off an evacuation.
May
- Relay official warnings and forecast tracks with their source and time.
- Help people find official evacuation routes and shelters.
Moral aspects Filled
- Tropical cyclones kill through surge, wind and flooding; timely truth saves lives.
- Poor and isolated people have fewer means to prepare and recover.
Who is affected
- Coastal residents
- Emergency responders
- People in low-lying areas
Owners Filled
Steward
Nobody owns a storm; the national meteorological service names and warns for it.
Master systems
- Regional specialized meteorological centre records

Capabilities and actions required Filled
- explain formation, structure and classification

Context of use required Filled
- Not applicable; a weather phenomenon.
- tropical depressions, storms and hurricanes or typhoons by intensity
- basins: North Atlantic, eastern and western Pacific, North Indian, South Indian, Australian and South Pacific
- annular and subtropical cyclones
- major hurricanes and super typhoons
- hypothetical hypercanes as a modelling concept
Sources Filled

- Wikipedia: Tropical cyclone - general description of the item
Open questions
- Should each basin be a separate entry?
- How should regional centre warnings be linked?
- The registry entry has merged basin aliases and a hypothetical concept; should they be split off?
