  • Understanding fire behavior is a huge challenge. Weather and fire behavior have coupled interactions that must be modeled appropriately. Above is the cutting edge in merging atmospheric and fire models. Lead by scientist Janice Coen at NCAR, ColoradoThe following animations show coupled weather-fire behavior model simulations of the growth of wildfires.The widely-observed "universal fire shape" evolves from the physics of fire interactions with the atmosphere.The fire starts as a line; constant easterly winds of 3 m/s are driving the fire from behind.  The fuel is "chaparral", a brush common in parts of CA, AZ, and the central Rocky Mtns.  Wildfire control in chaparral (a species that has adapted itself to recurring fires) is  notoriously difficult, because coupling Santa Ana winds, with droughts, long summers, and (often) steep terrain, creates intense, rapidly spreading fires.The misty field is smoke, denser and more red where the fire is burning most intensely.As the fire spreads, it evolves into a shape well-known to fire managers, with three parts: 1) the "head" - the leading edge of the fire where the heat is focussed, 2) two "flanks" - along the side, here the winds blow basically parallel to the edge of the fire, and 3) the "back" - the slowest moving part of the fire that creeps against the wind.  The heat from the fire rises in updrafts(s) that the winds focus at the head of the fire.  These updrafts draw warm air into their base from all directions, guiding the wind to flow along the flanks and focus the heat at the front.  In this way, the interaction of the fire with environmental winds creates a self-perpetuating, universal shape that is observed in fires in many conditions all around the world.

Tuesday we were given access to major Intel computers at Calit2 at UCSD and special connectivity between SDSU and UCSD (OptIPuter) from which this page is now being served (special thanks to John Graham, Eric Frost, Larry Smarr, John DeNune, andOctober 23, 2007 Cristiano). It is super fast now.” -- SDSU Department of Geography, Oct. 25, 11:00am. Site organized by Dr. Ming-Hsiang Tsou, SDSU http://map.sdsu.edu/
