How Much Does a Cloud Weigh? | U.S. Geological Survey
www.usgs.gov

I don't know anyone who is afraid to walk underneath a cumulus cloud because they are afraid it might fall on them. We don't think of clouds even having weight because they are floating. But, clouds are made up of a physical substance, water, and water is quite heavy, so clouds must have weight. We will explain this "paradox" to you if you read on.

      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.

    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.

          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.
