Wildfire Risk Map for a jet-stream shift

Built for educators teaching it to a class. Drop a live demo into a lecture or assign it as a shareable link — no lab installs. Simulate a jet-stream shift live below — adjust the inputs and watch it respond, right in your browser.

Wildfire / Fire SpreadLive

Controls

Presets

Fire spreads cell to cell, biased downwind and uphill — the two dominant drivers of real wildfire rate-of-spread. Rotate the wind and raise the slope to see how a fire front elongates and races upslope. For training and situational awareness only.

▶ Run in Python

Cells burned0
Wind15 @ 90°
Slope10°

Governing equation

Reading this result: Moderate wind and slope: the fire spreads roughly outward, with a gentle bias downwind and uphill.

Atmospheric Stability (CAPE)Live

Controls

Presets

When a rising air parcel stays warmer than its surroundings, it keeps accelerating upward — the fuel for thunderstorms. The pink area between the parcel and environment curves is CAPE, the convective available potential energy. Large CAPE means tall, violent storms; a stable profile suppresses them. This is the core of severe-weather forecasting.

▶ Run in Python

Data Inspector

CAPE (approx)18150 J/kg
Forecastsevere storms
Lapse rate7.5 °C/km

Governing equation

Reading this result: Steep environmental lapse (7.5 °C/km) keeps the parcel far warmer than its surroundings all the way up — huge CAPE fuels tall, violent updrafts.
