SWEX Sundowner Winds Experiment

Santa Ynez Mountains (SYM) in Santa Barbara County


Downslope windstorms at the lee of the Santa Ynez Mountains (SYM) in Santa Barbara County are one of the most significant fire weather hazards affecting populated areas. These gusty winds known as Sundowner winds, peak from early evening to mid-morning. A team of scientists will be in the Santa Barbara region in Spring 2020 to study these uncertain atmospheric conditions.

Societal Benefits

The Sundowner Winds Experiment (SWEX) is an atmospheric science research study to better understand the variability of downslope windstorms in coastal Santa Barbara County and will take place from 1 April–15 May 2020. The data will be used to refine and improve sophisticated computer simulations that are used for a wide range of applications, including the enhanced prediction of Sundowner winds.
