The
panels above show weather data from a coastal automated weather station
(part of the RAWS
network), capturing conditions that are representative of Santa
Ana winds. Of the 6 days shown in the graphs above, days 2-4 were
separated from the "normal" weather conditions data for simulations
with HFire. Criteria for being a Santa Ana "event" are relative
to average conditions for this coastal location, including higher wind
speeds (top panel), lower humidity and fuel moistures (2nd panel), higher
temperatures (3rd panel), and offshore wind direction (bottom panel).
Santa Anas can vary in their duration and intensity, and some regions
experience much more extreme fire weather conditions than those recorded
in this event at this location.
