This is more likely to occur in calm conditions,
when air near the surface is less well mixed with air higher up.
This is more likely to occur in calm conditions,

«The effect only happens when fast - rising air would form a thunderstorm anyway, and
when the air near the surface is moist,» Bell adds.»
Not exact matches
During the day,
when the hottest
air is usually
near the
surface, this has a cooling effect.
Kirchhoff's law only applies
when there is thermodynamic equilibrium, and that does not apply to the
air near the
surface of the Earth
when the thermal radiation is constantly changing, driven by a diurnal solar cycle.
When that magma
nears the
surface, those gases are released into the surrounding
air.
Fairly prevalent in goldfishes, swim bladder disease is
when the organ maintaining the fish's stability and bouyancy loses its ability to regulate
air properly, causing the fish to float
nearer to the
surface of the water, swim towards a particular side, or even end up upside down!
I'm calling it: seamless battles from the
surface of a planet, jumping in a starfighter for in -
air dogfights, going further into outer space battles, land on a destroyer or capital ship to continue the fight, get to the
nearest starfighter or escape pod
when the ship is compromised, the destroyer explodes in space as you head back down to the planet.
And no, there is no huge plunge in tropical or global
surface air temperatures
when the ocean circulation spins up because there is a
near - compensating decrease in poleward heat transport via the atmospheric circulation.
Radiative equilibrium at small LW optical thickness occurs
when the whole atmosphere has a temperature such that the Planck function is about half of that of the
surface (a skin temperature), whereas at larger LW optical thicknesses, the equilibrium profile has a signficant drop in the Planck function through the atmosphere, approaching half the OLR value at TOA and approaching the
surface value towards the
surface — of course, convection
near the
surface will bring a closer match between
surface and
surface -
air temperatures.
As evident in the figures the
near surface air temperatures are actually warmer over the Arctic Ocean (by over 1 °C in large areas)
when the sea ice absorbs solar radiation and transfers some of this energy as sensible heat back into the atmosphere.
When this water condenses this latert heat is given up so if this happens
near the
surface then local
air temperatures will increase slightly.
These take advantage of the remarkable stability of the earth's temperature
near the
surface and then use that as a source of heat in the winter
when the
air temperature is low and a source of cooling in the summer
when the temperature is high.
The shape of the CO2 band is such that, once saturated
near the center over sufficiently small distances, increases in CO2 don't have much affect on the net radiative energy transfer from one layer of
air to the other so long as CO2 is the only absorbing and emitting agent — but increases in CO2 will reduce the LW cooling of the
surface to space, the net LW cooling from the
surface to the
air, the net LW cooling of the atmosphere to space (except in the stratosphere), and in general, it will tend to reduce the net LW cooling from a warmer to cooler layer
when at least one of those layers contains some other absorbing / emitting substance (
surface, water vapor, clouds) or is space)
However,
when the ground warms a layer of
air near the
surface, it expands and rises, carrying away energy from the
surface.
Tornadoes often form
when warm, moist
air near the Earth's
surface rises and interacts with cooler and drier
air higher in the atmosphere.
