Sentences with phrase «temperature gradient exists»

The height above ground level must be specified, as on many occasions large temperature gradients exist in the lower layers of the atmosphere.

A strong Pacific zonal surface ocean temperature gradient has existed for the past 12 million years.

Existing models have difficulty duplicating climates in which the temperature gradient from the tropics to the poles is small, as suggested by the older paleo - climate data for the Eocene.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

The temperature gradient would then collapse, and the laws of thermodynamics would only permit an isothermal (3K) atmosphere to exist.)

-- The Equator - to - pole temperature gradient (Paleocene - Eocene) was much reduced compared to today, therefore the frost - free zone (a limiting factor for the rainforest) existed at higher latitudes than today.

[6] The amount of sunlight absorbed at the surface varies strongly with latitude, being greater at the equator than at the poles, and this engenders fluid motion in both the atmosphere and ocean that acts to redistribute heat from the equator towards the poles, thereby reducing the temperature gradients that would exist in the absence of fluid motion.

What do exist are waves invoked by the meridional temperature gradients.

«Look, nothing... is going to permit a stable thermodynamic temperature gradient, because for one to exist you must not be able to use it to do work, not even in principle.»

Large temperature gradients just don't naturally exist for any period of time.

DeWitt (and Robert Brown)-- To help you come to grips (grok) with the 2004 Verkley proof that top post Fig. 1 achieves thermal equilibrium non-isothermally (meaning there exists their proven temperature gradient eqn.

This warm nitrogen would balance out the temperature gradients that exist on the moon.

Therefore, the same temperature gradient will appear in the conductor and or along the walls of the cylinder as exists in the gas.

The evaporative, conductive and radiative processes combined then set up a thermal gradient causing an upward flow of energy from water to air from where that 1 mm layer touches the ocean bulk below, up across the cooler layer then to the Knudsen layer by reversing the normal (warm at the top and cool at the bottom) temperature gradient which exists from that 1 mm layer down to the ocean bottom.

This is because the troposphere is very opaque, and so the temperature gradient that would need to exist for the troposphere to be in radiative equilibrium would be far steeper than in reality.
