video: 1-minute interval GOES-14 SRSO-R visible (0.63 µm) images revealed the pulsing nature of the large Cougar Creek wildfire complex burning in southern Washington (not far southwest of Yakima) on 12 August 2015. The second fire blow-up that began around 1700 UTC apparently produced a pyrocumulonimbus cloud, with cloud-top IR Brightness Temperature (BT) values cooling past -40º C. Large amounts of smoke were transported northward and then northeastward away from the fire source region. view more
