http://emxsys.comFire Lookouts – Dynamic Spatiotemporal MarkersFire behavior is the manner in which a fire reacts to the influences of:fuel, weather, topography. Simply drag-n-dropFire Lookouts where youwant to know the potentialfire behavior. Fire Lookouts show fuelmodel, flame lengths forhead, flanks & heal, anddirection of max spread. Fire Lookouts react to changes in weather and temporal solar conditions.Developer Note: Fire Lookouts are custom composite renderables madefrom Placemark and GeographicText objects

Weather Scouts show: Sky cover Wind speed and direction Air temperature (F) Relative humidity (%) Weather Scouts are spatiotemporal markers.Developer Note: Weather Scouts are custom composite renderables madefrom Placemark and GeographicText objects.

http://emxsys.comWind Affects Fire Flames are inclined towardsthe fuel Fuels are heated byradiation and convection Direction of max spread isinline with wind direction

http://emxsys.comSlope Affects Fire Upslope fuels are closer tothe flames. The results are very similarto the effect of wind. In the absence of wind,direction of max spreadfollows upslope vector

http://emxsys.comSolar Radiation Affects Fire Changes the fuel flammability Solar Radiation preheats the fuel Drives off moisture, making the fuelmore flammable Changes with time and aspect Creates an unstable fuel bed

http://emxsys.comCPS Alignment of Forces Concept Variations in Wind, Slope and Preheating explain changes in firebehavior Wind, Slope and Preheat are the primary forces Fire Behavior is affected by variations in: Strength Dominance Alignment In-Alignment Forces Exacerbate Fire Behavior Out-of-Alignment Forces Reduce Fire Behavior
