If a larger mass of warm air has to pass through it, more energy is transferred, through the evaporator's fins (so that even the evaporator's design and, in particular, its exchange surface play an important part) from the air to the liquid refrigerant allowed inside it by the TEV or orifice tube so it expands more and, along with the absolute pressure inside the evaporator, the refrigerant's vapor superheat (the delta between the boiling point of the fluid at a certain absolute pressure and the temperature of the vapour) increases, since after expanding into saturated vapour, it has enough time to catch enough heat to warm up further by vaporizing the remaining liquid (an important property of a superheated vapour is that no fluid in the liquid state is carried around by the vapour, unlike with saturated vapour).

Large masses of warm moist air can produce more precipitation, leading to unprecedented flooding.
When these loops become very pronounced, they detach the masses of cold, or warm, air that become cyclones and anticyclones and are responsible for day - to - day weather patterns at mid - latitudes.
Glaciers and ice caps in Arctic Canada are continuing to lose mass at a rate that has been increasing since 1987, reflecting a trend towards warmer summer air temperatures and longer melt seasons.
The warm air above nocturnal or polar inversions, or even stable air masses with small positive lapse rates, are warmer than otherwise because of heat capacity and radiant + convective heating during daytime and / or because of heating occurring at other latitudes / regions that is transported to higher latitudes / regions.
Re 346 ziarra — the flow of heat (between adjacent layers of material via conduction, convection, or mass diffusion, or potentially across larger distances via emission and absorption of photons) will be from hot to cold (or from higher to lower concentrations of a substance carrying heat, which might end up being from cold to hot in some conditions, such as a wet surface cooling by evaporation into warm dry air).
Seems to me the debate about AGHG global warming and increasing TC frequency / intensity / duration boils down to the fact that as sea surface temperatures, as well as deeper water temperatures rise, the wallop of any TC over warmer seas without mitigating circumstances like wind sheer and dry air off land masses entrained in the cyclone will likely be much more devastating.
The point isn't a «perpetual increase in atmospheric pressure» — that's a misnomer — if you consider the MASS of the atmosphere that is continuously «pumped» from cold air to hot air to cold air again, high up in the atmosphere — that creates «potential energy» from the kinetic energy of the convection — adiabatic expansion of the atmosphere is the result — the adiabatic compression occurs on the return trip of the previously warmed (from radiative energy) air as it completes the «cycle» as it comes back down!
With the source regions warming, the polar and artic air masses would modify (warm), and the mechanism that transports them equatorward (the polar jet) would weaken.
