What it is Filled
A large-scale rotating air mass around a centre of low atmospheric pressure, spinning counterclockwise in the northern hemisphere and clockwise in the southern, including tropical cyclones known as hurricanes and typhoons, extratropical cyclones of the mid-latitudes that bring most temperate weather, subtropical cyclones, polar lows and the polar vortex, and related phenomena such as the Pineapple Express atmospheric river; cyclones drive storms, rain and wind and are tracked and forecast by meteorological services, and vortices are also observed on other planets.
Why it exists Filled
Let an agent explain cyclones and their kinds, relay formation, forecasting and hazards from meteorological sources, distinguish tropical from extratropical cyclones and from tornadoes, and route warnings to official services.
Distinguishing features Filled
- Low pressure rotation
- Coriolis-determined spin
- Tropical and extratropical types
- Major weather driver
What robots and AI may and may not do Filled
Must not
- Issue its own cyclone warnings or all-clear signals that contradict official services.
- Spread unverified forecasts or rumours that cause panic or complacency.
- Advise people to stay in an evacuation zone against official orders.
- Misrepresent the link between climate change and cyclones beyond what evidence supports.
Only with a human decision
- Ordering or lifting evacuations.
- Directing emergency resources.
May
- Report forecasts, tracks and warnings issued by official meteorological services.
- Help people find shelters, evacuation routes and preparation advice from authorities.
Moral aspects Filled
- Cyclones kill most where warnings fail to reach poor and remote communities.
- Recovery aid must reach all affected people fairly.
Who is affected
- Coastal residents
- Emergency responders
- Fishers and sailors
Owners Filled
Steward
Nobody owns the weather; national meteorological services issue the authoritative warnings.
Master systems
- Official meteorological warning systems
- Tropical cyclone best track archives

- tropical cyclones: hurricanes, typhoons, cyclones
- extratropical cyclones and frontal systems
- subtropical cyclones such as in the North Atlantic
- polar lows and the polar vortex

- Wikipedia: Cyclone - general description of the item
Open questions
- Should tropical cyclone and extratropical cyclone be separate primary entries?
- How should meteorological services be linked?
- The registry entry has merged aliases naming distinct phenomena; should they be split off?
