The CAWFE Modeling System for Wildland Fires
VIEW VIDEO SIMULATION HERE
Tubbs Fire simulation created using NCAR CAWFE model (Coupled Atmosphere-Wildland Fire Environment). UCAR, NCAR, Coen, J. L.
Ignition: 10/8/17 near Calistoga, CA.
CAWFE was applied to investigate the flow regime and underlying mechanisms associated with the extreme winds and fire behavior during the Tubbs Fire.
The fire's heat flux is show in the upper color bar (in W m-2). Wind speed arrows (in m s-1) point downstream and are colored according to the color bar at right. Vectors are shown every 3 grid points.
As Diablo winds traveled south down the Sacramento Valley and fanned out southwestward over Wine Country, their strength waxed and waned and their direction wavered, creating varying locations near fire origins where wind overrunning topography reached 30-40 m s-1. The flow created peak wind speeds exceeding 40 m s-1 at the crest of some lesser hills. The flow drove the Tubbs Fire over 19 km in 3.25 h into urban areas of Santa Rosa, CA.

California is experiencing more frequent and intense extreme weather events, including this year’s historic floods following a five-year drought, devastating wildfires, and a deadly heat wave. These impacts are expected to worsen as a result of climate change over the coming years...

It’s peak wildfire season in California, and Monday was one of the worst days in state history. More than 60 blazes are currently underway statewide.
At least a dozen wildfires sprung up Sunday night in and around Napa and Sonoma

California wildfires have torched about 200,000 acres — a collective area roughly the size of New York City — in what is being called the deadliest wildfire in state history.
