PyroCb in South Africa

The Garden Route Fires had been burning since about 24 October 2018 near George along the southern coast of South Africa (media story). On 29 October, EUMETSAT Meteosat-11 High Resolution Visible (0.8 µm), Shortwave Infrared (3.92 µm) and Longwave Infrared Window (10.8 µm) images (above) showed an elongated west-to-east oriented thermal anomaly or fire “hot […]

PyroCb in Texas

A large pyroCumulonimbus (pyroCb) cloud developed from the Mallard Fire in the Texas Panhandle on 11 May 2018, aided by warm temperatures and strong winds ahead of an approaching dryline (surface analyses). 1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed […]

PyroCb in Argentina

A large cluster of fires burning in central Argentina became hot enough to generate a brief pyrocumulonimbus (pyroCb) cloud on 29 January 2018; according to media reports, on that day there were winds of 55 km/hour (34 mph) and temperatures of 37 ºC (98.6 ºF) in the vicinity of these La Pampa province fires. GOES-16 […]

PyroCbs in British Columbia

Early on 12 August 2017 two pyroCbs formed in British Columbia, Canada. GOES-15 detected the smoke plume and pyroCb cloud, as well as the fire hot spots. The first pyroCb cloud (near 51.8º N, 123.2ºW) developed around 03:30 UTC . The second formed about 1.5 hours later, at 05:00 UTC (near 53.1º N,  121ºE). Starting at […]

PyroCb in Australia

On 04 December 2016 a pyroCb developed to the west of Toowoomba in Queensland, Australia. A Suomi NPP VIIRS true-color image around 04:16 UTC (above) showed the early stage of the smoke plume in the Cecil Plains area, about 2 hours prior to the pyroCb formation. Himawari-8 monitored the temporal evolution of the smoke plumes and […]
