Scientists studying California's devastating wildfires are using a powerful new radar system that could help them better understand how they spread and how firefighters should fight them
The mobile Ka-band Doppler radar rig is similar to what meteorologists use to monitor the weather, but it is finely tuned to detect ash particles in a fire plume, said Craig Clements, the director of San Jose State University's Fire Weather Research Laboratory.It works by emitting bursts of millimeter wave energy that bounce off particles and can be detected by the radar.
— SJSU FireWeatherLab October 26, 2019 The radar can also see through the smoke to see structures such as fire whirls, which he compared to mini fire tornadoes that are erratic and dangerous and often hard to see."Right now, we're doing research because we want to understand the physics of wildfire spread and how fires create their own weather and all that fire atmosphere interaction that we do, so it's scientifically very valid, but there's an operational need too.
