PyroCb in Russia

On 30 April, JMA Himawari-8 “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.4 µm) images (above) showed the formation of the first known pyroCb of the 2019 Northern Hemisphere wildfire season. The pyroCb developed within the warm sector of an approaching midlatitude cyclone (surface analyses) in the Russian Far East, […]

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 […]

Another pyroCb in Russia

On 15 August 2017 a pyroCb formed in Russia. Himawari-8 detected the smoke plume and pyroCb cloud, as well as the fires hot spots. The pyroCb cloud (~62.8º N, 122.4ºE) formed around 3:10 UTC . Starting at 2:30 UTC on 01 July, the animation below shows Himawari-8 0.63 µm visible (left) and 3.9 µm shortwave IR […]

Two PyroCbs in Russia

On 22 June 2017 two pyroCbs formed north of Lake Baikal in eastern Russia. Himawari-8 detected the smoke plume and pyroCb cloud, as well as the fires hot spots. The first pyroCb cloud (~58.3º N, 105ºE) formed around 8:30 UTC . The second formed shortly after around 58.9º N  106.9ºE. Starting at 8:00 UTC on 22 June, […]
