New research finds the temperature of a wildfire is a better predictor of what’s in the smoke than the type of fuel being burned - a surprising result that will advance a wildfire smoke-modeling tool currently under development.
Understanding how wildfires impact air pollution and the composition of Earth’s atmosphere is critical for communities near and far because smoke from wildfires can travel long distances and have adverse health impacts on citizens.
The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.
