WILDFIRES ARE INFLUENCED BY WIND AND TOPOGRAPHY |
| Caption: |
Idealized diagrams of flame shape and processes associated with a spreading fire under three conditions: (a) flat topography and no wind; (b) flat topography with wind; and (c) hillslope topography where slope drives fire uphill. Solid red arrows indicate motion of air currents and dashed red lines show radiant heating from the fire. (Modified after Rothermel, R. C. 1972. A mathematical model for predicting fire spread in wildland fuels. U.S. Forest Service Research Paper INT-115) |
