As MIT Emeritus Professor Richard Lindzen has explained, the decline in storminess is a consequence of
reduced temperature differentials between the tropics and exo - tropics that arise when global average temperatures are warmer.
Global warming is indeed expected to
reduce the temperature differential between the poles and the equator.
So if one increases the rate of downwelling IR (thereby increasing the evaporation rate) then the increase in upward energy flow caused by the fall in the temperature of that 1 mm layer will be greater than the decrease in upward energy flow that will result from
any reduced temperature differential between the topmost Knudsen layer and the ocean bulk arising from the application of Fourier's Law.
The main point is that the greater moisture in the air and
reduced temperature differential affects the winds around the arctic with the result that we get blocking patterns leading to more snowfall.
The air circulation systems in both hemispheres move back equatorward and the ITCZ moves nearer the equator as the speed of the hydrological cycle decreases due to the warming stratosphere
reducing the temperature differential between stratosphere and surface.

This
reduces differential temperatures as much as 100 degrees F.
Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differenti

If the
temperature differential reduces because of a warming Arctic then the jet stream weakens and, again, like a river on a flat bed, it will meander every time it comes across an obstacle.
Also, I've read somewhere (sorry no ref) that GW may decrease the
temperature differential between the poles and the equatore hence
reducing Hurricane intensity.
When the Arctic sea ice «thermometer» opens up it works to
reduce the oceanic conveyor belt volume as the
temperature differential between tropics and pole is
reduced.
Note that this means the
temperature differential across the wall has
reduced to only (just over) 1 °C.
As the gas mixes energy is transferred from the warmer gas to the cooler gas and the
temperature differential reduces.
