Where is the LX S80?

As should have been clear from what I wrote, in the bottom third of the
thermal the air is still warmer, but steadily mixing in surrounding air.
Once properly formed the momentum of the tons of air moving is presumed to
keep the circulation active. Air close to the ground is also more humid
which increases the buoyancy. We did not fully model the mechanism, just
took measurements that illustrated the scale and characteristics of
meso-scale air motion in a range of situations, including convective
weather.

significant indicator, H2O molecules being lighter than O2 or N2.

So thermals rise, not because of the sun heating the ground and making a
bubble of warm air that breaks free, but because somehow a more humid
bubble of air is created. What mechanism creates the bubble of humidity?
