Sentences with phrase «when air near the surface»

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, when air near the surface is less well mixed with air higher up.
«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.
