I love how you’re mixing metric and imperial in the title 😂

TIL some people think 1 cubic kilometer is “small”
1 cubic kilometer of anything will basically fucking kill you.
What about 1 cubic km of air at one standard atmospheric pressure?
It may take a hundred years, but it will kill you.
Touché
For reference: air density is roughly 1kg/m³ [see note]. So the same volume of air is roughly 10⁶ tons. The air in the cloud weights 2000 more than the water.
NOTE: it’s 1.3kg/m³ on sea level, 0.9kg/m³ at 3km over sea level, I think that 1kg/m³ is a safe bet.

big thing looks small when far away.

there are quit a bit of satellite image you can check, I am not specialist in this to answer your question. (like are they consider connected or in the same “group” of origin? ) But half the planet is likely not possible because of how they are effected by the Earth spinning and drag + advection. ie. it means if you want to cover half the planet, you can only cover either northern or southern hemisphere. The cloud formed on equator area will be spread into 2 direction and then torn apart.
