PyroCbs in Western Australia

Large bushfires burning in the southern portion of the state of Western Australia produced three pyroCb clouds on 01 March 2019. JMA Himawari-8 “Red” Visible (0.64 µm) images (above) showed that the pyroCb clouds drifted southeastward after formation. Himawari-8 “Clean” Infrared Window (10.4 µm) images (below) further revealed the 3 distinct pyroCb pulses — 2 […]

Cocklebiddy Fire PyroCb in Australia

A slightly longer animation — covering the period from 20:40 on 6 December to 09:40 UTC on 7 December — of Himawari-8 Visible (0.64 μm), Shortwave Infrared (3.9 μm) and Infrared Window (10.4 μm) images is shown below. The pyroCb cloud formed near the center of the images, and the cold anvil of the cloud […]

Another PyroCb in Cecil Plains

Another pyroCb formed on 06 December in Cecil Plains in Queensland, Australia. Starting at 4:00 UTC on 06 December, the animation below (also available as an MP4) shows Himawari-8 0.63 µm visible (left) and 3.9 µm shortwave IR (right) . The pyroCb cloud (~28.2º S, 151ºE) formed around 7:50 UTC. In the shortwave IR images, […]

PyroCb in Cecil Plains

Towards sunset a pyroCb formed in Cecil Plains in Queensland, Australia. Starting at 7:00 UTC on 05 December, the animation below (also available as an MP4) shows Himawari-8 0.63 µm visible (left) and 3.9 µm shortwave IR (right) .

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 […]
