Fig. 5: Key stages of ANYSO pyroCb activity observed from satellite.

From: Australia’s Black Summer pyrocumulonimbus super outbreak reveals potential for increasingly extreme stratospheric smoke events

Fig. 5

Grayscale shading indicates daytime BT11 from AHI, with colder, high-altitude cloud tops displayed in white. Orange shading coincides with smoke-perturbed pyroCb cloud tops. Multi-color shading indicates nighttime BT11, with high-altitude cloud tops displayed in red, yellow, and brown (e.g., #16). PyroCb sub-event numbers match those in Figs. 1 and 4, with a–e highlighting sub-events observed during ANYSO’s first phase and f highlighting peak activity during phase two. AHI pixels with active fires are displayed in pink. The approximate position of an approaching surface cold front is denoted in white. Animations of this imagery are provided in Supplementary Information for both ANYSO phases.
