Big Elk Fire Simulation
Big Elk Fire Simulation |
||||||||||||||||||||||||||||||
| This simulation begins several hours in the early period of the Big Elk Fire, which ignited in the afternoon of 7/17/02 northwest of Lyons, CO. Fire behavior was extreme reflecting the extreme conditions in the area and throughout Colorado (including the lowest fuel moistures ever recorded in the area). Initial spread was rapid, moving up a south slope of ponderosa pine with crowning and torching. |

This animation, which begins one hour before fire ignition, is of about 3.5 hours in the afternoon of 7/17. Red is a buoyancy isosurface of 10 degrees warmer than the environment, and the misty white field shows smoke. The arrows are the near-ground-surface wind vectors, which are affected both by meteorology and by the fire itself.
