Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).

Because contraction of the vortex tends to require faster rotation (conservation of angular momentum), which increases centrifugal acceleration, which opposes contraction, it becomes hard for air to flow in sideways to take the space of warmer air that is rising when the air is spinning; thus, a rising column of air can pull up on air from below.

According to data from the World Health Organization, rising temperatures on the planet are killing off the equivalent of a mid-sized city every year; about 150,000 annual deaths can be attributed to global warming, from causes including heat waves, air pollution, infectious disease, food safety and production, flooding and more.

Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

If in exceeds out and the diffential MUST exist from top to bottom of the atmosphere, then before the hotter air can migrate to the deep ocean, the daily temerature cycling will force the hotter air at the bottom into an overall equlibrium ie hotter air will rise — or more correctly since GHGs have heated the air up more at the bottom, then the sun induced daily warming will add more heat to the top, & less at the bottom to force the equilibrium — ie effectively hot air rising even if not in actuality.

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.
