NASA’s ER-2 Spy Plane Studies How Wildfires Spawn Storms
NASA has begun flying its modified U-2 spy plane, the ER-2, to study the poorly understood link between large wildfires and the intense thunderstorms they can produce. The aircraft, which can reach altitudes of over 70,000 feet, is equipped with specialized instruments designed to sample the smoke, heat, and atmospheric conditions within and around active fire plumes.
The research aims to answer a key question: how do some wildfires grow so large and violent that they generate their own storm systems, including dangerous pyrocumulonimbus clouds—essentially thunderstorms born from fire? These fire-generated storms can spread flames via lightning, create erratic winds, and complicate firefighting efforts.
By collecting detailed data on temperature, moisture, aerosol composition, and atmospheric dynamics at extreme altitudes, scientists hope to improve computer models that predict fire behavior and extreme weather events. The findings could also inform climate models, as wildfire-driven storms may become more frequent as global temperatures rise.
The ER-2 mission represents a rare applied use of the Cold War-era spy plane platform, demonstrating how military hardware continues to serve scientific objectives in the modern era.
