We show the Camp Fire’s explosive growth came from plume-coupled spotting: embers lofted, transported, and deposited in organized zones 5–10+ km ahead, igniting new fire fronts. https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2025JD04579817 Mar 2026 20:31 +0000at://did:plc:dfgeyawezkq6ry3pecit3mrs/app.bsky.feed.post/3mhbswj57t225https://bsky.app/profile/neillareau.bsky.social/post/3mgvpikszgs22Fires, plumes, and wind shifts.

We document tornado-strength (98 mph) counter-rotating vortices that developed within California’s 2021 #DixieFire. These fire-generated vortices reshaped the fire front and spread, posing immediate risks to firefighters and civilians. https://doi.org/10.1175/MWR-D-24-0254.115 Nov 2025 01:48 +0000at://did:plc:dfgeyawezkq6ry3pecit3mrs/app.bsky.feed.post/3m5n3cc3suk2bhttps://bsky.app/profile/neillareau.bsky.social/post/3lv7pmknags25Cumulonimbus.30 Jul 2025 22:53 +0000at://did:plc:dfgeyawezkq6ry3pecit3mrs/app.bsky.feed.post/3lv7pmknags25https://bsky.app/profile/neillareau.bsky.social/post/3lujigmzu2k2fACSL ALQDS22 Jul 2025 02:46 +0000at://did:plc:dfgeyawezkq6ry3pecit3mrs/app.bsky.feed.post/3lujigmzu2k2fhttps://bsky.app/profile/neillareau.bsky.social/post/3lsz2urcahk2rDiverting money from science funding for immigration crack downs is dumb.
