as a consequence of a physical change (condensation and
precipitation remove water vapor from the atmosphere).
Because
precipitation removes water, sinking air is often dry, and lapse rates up to dry adiabatic can be sustained even though they would be unstable to moist convection; heat and humidity build up until conditions favor convection, until something triggers it, and then it can sustain itself until the energy is drained.

Current methods to
remove arsenic include
precipitation, adding lime or coagulants to
water, using membranes to filter it out, or using an ion exchange process.
If the planet cools too much, less
water will evaporate and there will be less
precipitation to
remove CO2; the CO2 will build up, warming the planet.
Removing water by
precipitation will lower the pressure in that column but only as this process continues.
Once in the stratosphere the SO2 did slowly mix with
water vapor to form H2SO4 (sulfuric acid), but in the stratosphere there is no
precipitation to allow for it to be quickly
removed.
