See the weather. Know what's next.
Aethopia puts cyclone bulletin summaries, global wind data and a physical model on one turnable globe: where a storm is, where it is headed, how strong the wind around it is.
What this site is for
Agency figures are unit-converted and rounded. What no agency publishes — the shape of the wind field, how far the gales reach, how a past storm actually moved — is filled in here with a physical model, and each of those is marked as computed.
Global wind field
Wind at ten metres, drawn as particles, coloured by speed.
Forecast tracks
Compiled from agency bulletins; wind speeds converted from knots to km/h and names translated by Aethopia — not official text.
Wind footprint
Fresh, gale, storm and hurricane bands drawn along the forecast track.
Replay past storms
Mangkhut, Hato and other cases replay from the start, showing how wind built across the city.
How it was built
The globe, the particles, the physics engine, the data plumbing and every line of copy are written by Aethopia. The wind field is not a stock image: it is computed cell by cell from global model data. Figures issued by agencies around the world are drawn together by Aethopia's own physical model.
Five lines this site holds
Written down so that whoever wants to relax one later — the author included — can see why it was drawn in the first place.
01Every figure has a source
Each number can be traced to the agency and the bulletin it came from. Units are labelled where they are converted, and the values themselves are never adjusted.
02What is computed says so
Anything worked out here carries a mark. It is never quietly mixed in among the agency figures.
03Physics, not machine learning
The wind field comes from a parameterised physical formula. Which formula it is, and whose paper it came from, is named on the sources page — not a box you cannot see into.
04The limits are written down too
Known biases, the parts never calibrated and the cases where it breaks are listed one by one on the sources page — including the ones that do this site no favours.
05Everyday nudges, never the official call
Take an umbrella, drink more water, put on a jacket, keep off open ground — that much this site will say. Whether a warning signal goes up, whether schools close, whether a flight is changed, it will not. Those three belong to the official bulletin, and being wrong about them would cost you, not this site.
Numbers you can check
Only what can actually be counted. Each one is derived from the site's own data, not typed in.
