Why was this NASA spy plane over B.C.?

NASA's high-altitude spy plane was recently spotted over British Columbia's wildfires to investigate "fire clouds," or pyrocumulonimbus storms, which can spawn fire tornadoes and lightning. These unique storms are becoming more frequent due to climate change, and the mission aims to better understand their impact on fire behavior. CBC's Johanna Wagstaffe explains that this research could lead to improved fire management strategies and a better grasp of how climate change affects extreme weather events.
