1-minute Mesoscale Domain Sector GOES-19 (GOES-East) Water Vapor images (above) displayed an intermittent signature of subsidence-induced warming/drying (brighter shades of yellow to orange) that led to the development of strong downslope winds in the Front Range of Colorado on 17 December 2025. Several sites recorded peak wind gusts in excess of 100 mph.A toggle... Read More

10-minute Full Disk scan JMA Himawari-9 AHI Visible, Shortwave Infrared and Infrared Window images (above) showed multiple pulses of pyrocumulonimbus (pyroCb) clouds that were spawned by a large bushfire in southwest Queensland, Australia on 13 December 2025. The pyroCb cloud pulses exhibited a cloud-top 10.4 µm infrared brightness temperature (IRBT) of... Read More

10-minute Full Disk scan JMA Himawari-8 Visible, Shortwave Infrared and Infrared Window images (above) showed 2 pulses of pyrocumulonimbus (pyroCb) clouds that were spawned by a large bushfire in Western Australia on 17 November 2025. The pyroCb cloud pulses exhibited a cloud-top 10.4 µm infrared brightness temperature (IRBT) of -40ºC... Read More

The Bald Mountain brush fire had been burning for several days in far western Virginia — but flared up on 12 November 2025, due to ongoing moderate drought conditions and an increase in winds west of a surface trough of low pressure. 1-minute Mesoscale Domain Sector GOES-19 (GOES-East) Visible images with an overlay of the Fire Detection and Characterization Algorithm...
