I'm more interested in the white clouds at about 4 o'clock, halfway in from the visible horizon.
It looks like a splash in a liquid surface, with droplets thrown upwards, but a gas surface doesn't behave like that.
What might be causing that?
Better to think in terms of "fluid" than "gas" in understanding atmospheric and cloud dynamics. In fact, even on Earth clouds behave that way. We have similar clouds, probably resulting from similar processes.
I've heard meteorologists refer to such (growing/rising) cloud structures as "burning towers".
I spent years working with meteorologists and never once heard
them refer to (ice filled) cumulonimbus clouds as "
burning towers".

<<Cumulonimbus (from Latin cumulus, "heaped" and nimbus, "rainstorm") is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes and hailstones. Cumulonimbus progress from overdeveloped cumulus congestus clouds and may further develop as part of a supercell. Cumulonimbus is abbreviated Cb.
Towering cumulonimbus clouds typically reach to as much as 12 km, with extreme instances as high as 21 km or more. Well-developed cumulonimbus clouds are characterized by a flat, anvil-like top (anvil dome), caused by wind shear or inversion near the tropopause. The shelf of the anvil may precede the main cloud's vertical component for many miles, and be accompanied by lightning. Occasionally, rising air parcels surpass the equilibrium level (due to momentum) and form an overshooting top culminating at the maximum parcel level. When vertically developed, this largest of all clouds usually extends through all three cloud regions. Even the smallest cumulonimbus cloud dwarfs its neighbors in comparison.>>
