00:00Wildfires can create their own weather, and that can change how they spread.
00:04Now, researchers are sending weather balloons directly into rising wildfire plumes to understand what happens next.
00:11Firefighter and researcher Mark Castelnu, working with Catalonia's graph team,
00:16is measuring temperature, wind, and humidity inside and outside these towering columns of hot air.
00:22Why does that matter?
00:23As a plume grows, it can interact with the surrounding atmosphere,
00:27triggering powerful air movements and sudden changes in wind direction or speed.
00:32Those shifts can make a fire spread rapidly and put firefighters in greater danger.
00:37In some extreme cases, the plume can develop into a pyrocloud,
00:41a cloud formed by intense fire-driven rising air.
00:44The danger may not disappear at sunset either.
00:47A fire can leave the surrounding atmosphere warm and turbulent enough to help sustain intense burning overnight.
00:53By combining balloon measurements with weather data and computer models,
00:57researchers hope to improve predictions and give firefighters better information when conditions change.
