Sentences with phrase «adiabatic warming of air»

Not exact matches

This is the result of adiabatic warming, where air is compressed from low pressure (at the top of a mountain) to high pressure (at sea level).

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).

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!

The lower atmosphere is mixed sufficiently so that air warms and cools at a rate of about 5 degrees F / 1000 feet, or slightly less steep than the dry adiabatic lapse rate (of 5.4 degrees F / 1000 feet).

If that happens, the column will only cool at the saturated or wet adiabatic rate of only 5 deg C per 1000 meters and at this rate, it will actually be warming with respect to the surrounding air at 1.5 deg C per 1000 meters.

Also adiabatic cooling of convecting air, containing CO2, will radiate heat to a cooler area, ie above, not to the warmer surface.

Still air with either little vertical shear and relatively weak warming of the ground or with so much vertical shear that turbulence occurs and irreversibly physically mixes the air parcels faster than «reversible» adiabatic expansion can keep up favors the «isothermal» pole, although this too is almost never precisely observed.

Warm ground (strong heating of the ground) and non-turbulent vertical flow due to convective shear forces slow enough to allow approximately adiabatic expansion and compression to occur in the overturning convective air parcels favors the DALR.

As a consequence of the different adiabatic lapse rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes.

However, the atmosphere is unbounded, so if there were even a small amount of local heating occurs due to absorbing IR, the warmer air would rises and then cool by adiabatic expansion.
