Fig. 9: Spatiotemporal evolution of the third vortex.

From: The 2019/20 Australian wildfires generated a persistent smoke-charged vortex rising up to 35 km altitude

Fig. 9

a Time evolution of the vortex from 7 matching sections of CALIOP during its first period over Antarctica. We use here daily orbits of CALIOP, hence the high level of noise. The x-axis is mapped over longitude due to the proximity of the pole. b Time evolution of the third vortex from 7 matching sections of CALIOP during its second period. c Time evolution of the vortex according the ECMWF analysis from eight vorticity snapshots at the level of maximum vorticity. The background is shown for 7 February where the main vortex is also visible. The yellow curve shows the trajectory of the vortex in the IFS, the magenta crosses mark the TROPOMI AI centroid. d Altitude of the vortex core as a function of time. e Maximum vorticity of the vortex core as a function of time.
