Which mechanism causes atmospheric stability when air sinks within polar cells?

💡 Explanation

When air descends in polar cells, adiabatic compression warms the air because the pressure increases, leading to a temperature increase per the dry adiabatic lapse rate that is potentially higher than the surrounding environmental lapse rate resulting in stable conditions. Therefore, atmospheric stability results, rather than instability, condensation release, or orographic lifting which require surface topography and different pressure changes.
