[ LAYER 01 / 03 · WIND · T+18H ]
Cyclone
Wind arrives as two numbers per cell — speed and bearing — at 10 m and 100 m above ground. Ask for a point, a line or a box. Storm cores are resolved, not smoothed away.
- Grid

- Cadence
- 10 min
[ LAYER 02 / 03 · PRESSURE · T+30H ]
Isobars
Sea-level pressure, every ten minutes, as a field or as contours. Isobar draws the lines for you — GeoJSON at any interval — so the low on your map is the low in the model.
- Interval
- 4 hPa
- Lowest
- 968 hPa
[ LAYER 03 / 03 · TEMPERATURE · T+42H ]
Thermal
Air temperature at two metres, plus the dew point and the freezing level. The model is checked against itself every hour; the bias column tells you how far to trust it.
- Height
- 2 m
- Bias
- ±0.4 °C
[ ALOFT · 250 HPA · T+54H ]
Jet stream
Above the weather is the wind that moves it. Isobar serves 14 pressure levels up to 100 hPa, so a route at cruise altitude reads the same field as a turbine at hub height.
- Level
- 250 hPa
- Peak
- 92 m/s

[ 04 / 04 · FAQ ]
FAQ.
Is this real weather data?
No. Isobar and its field are fictional; the wind on this page is a synthetic model built for a design template.
Why particles instead of a map?
Because wind is a motion, not a colour. Each line is one parcel of air moving for a few seconds.
Can I stop the motion?
Yes. Hold in the top strip freezes the wind and the ticker; reduced-motion settings show still frames.
What does T+72h mean?
Hours ahead of the model run. Scrolling the page plays the forecast forward.
Does it work without WebGL?
You get the same six frames as still images, in order.
