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.

Governing equation

R = R_{0} (1 + ϕ_{w} + ϕ_{s}), ϕ_{w} = 0.60, ϕ_{s} = 0.22

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