The important effect of this decrease in pressure is this: in
a given volume of air, there are fewer molecules present.
The team ran simulations to gauge the effect of midair collisions on a storm's strength, which they measure as flux, the number of particles passing through
a given volume of air in a given amount of time.
In a matter of weeks, the molecules in
any given volume of air will circumnavigate the globe.

give the car dramatic differentiation, making it seem wider (and therefore lower) while feeding a larger
volume of cooling
air to the intercoolers.
Combined, those sources

Given that thin ice — as you explained — boosts heat transfer from ocean to
air, is a focus on ice
volume as an indicator
of the «health»

of a better word) a distraction?
Given that the Central Intelligence Agency was one
of the main sponsors
of the Academy report on atmospheric intervention and a companion
volume on carbon dioxide removal from
air, there's also plenty
of room for conspiracy theories.
The total
air column mass is constant, and
given the adiabatic control
volume as shown neither heated or cooled by surroundings nor by radiation (GHG - free) or by interaction with adjacent
air or ground; we need to find the equilibrium temperature profile
of this gas column and we need only 2 laws: the 1st and 2nd thermo laws.
He says to take examples from real world, (as he's done with the example
of packets
of air rising which is already well known and which is what
gives us our weather), but on a non-rotating Earth it's the difference
of temperature provided by the Sun between the equator and the poles which sets up the basic pattern
of packets
of air on the move (which is wind, wind is
volumes of air on the move) from the equator to the poles where they cool and are drawn back to the equator where the heating cycle begins again.
And, just to round it off, they don't have sound because it takes
volumes of air to
give us sound, there is no sound in empty space.
If the
air contains a large percentage
of water vapour then that vapour may well end up being more responsible for any
air motion that dry
air of a similar
volume given the expansion ratios.
However there is a contraction
of volume but that immediately pulls in more
air from the surroundings so the original
volume then contains more mass than before which must
give a rise in surface pressure rather than a fall.
However, as the water vapor rises the lapse rate means that the
volume of air cools and eventually the water vapor condenses into water droplets and then into ice latent heat is
given off to the surrounding
air at each
of these phase changes, with two effects.
Our atmosphere held in place by gravity acting on their mass which
gives them weight relative to each other, because they are different from each other, and those differences are critical to understanding heat transfer by convection which is how we get our winds and weather, which we get from differential heating
of volumes, packets,
of fluid
air.
It's a small effect, much smaller in the atmosphere than the expansion due to the reduction in pressure as the
air rises, but the reduction in
volume at a
given pressure due to condensation is included in accurate computations
of adiabatic lapse rates.
Four speakers, two at the top and two at the bottom,
