Sentences with phrase «surface evaporative cooling»

This leaves only the surface evaporative cooling, which is balanced by global precipitation, as the term to accommodate such an increase.

The main issues relate to the downwelling longwave (LW) radiation and the hydrological cycle, and thus the surface evaporative cooling.

«Clouds, which largely determine the geographic patterns of DTR, greatly reduce DTR by sharply decreasing surface solar radiation while soil moisture decreases DTR by increasing daytime surface evaporative cooling.

Wramneby et al (2010) explored the regional interaction between climate and vegetation response using a RCM set - up, and highlighted the importance of this interaction for assessing the mean temperature response particularly at high latitudes (due to the role of vegetation in snow covered areas) and in water limited evaporation regimes (due to the role of vegetation in controlling surface evaporative cooling).

Not exact matches

Accelerant poured on the concrete actually protects it by providing a cool, evaporative surface..

In a matter of seconds, when you put the food in the fryer, water starts evaporating, vapors form and escape the surface, oil penetration starts, and heat begins to rise while at the same time there's evaporative cooling off at different points in the food.

The increase in evaporative cooling with increased surface temperature is therefore limited by the increase in precipitation, not by the increase in sea surface temperature.

From December through March a 5 - mm suit might be in order, and a cover - up to mitigate evaporative cooling during surface intervals.

With dry cooling, one wants to have enough surface area so that convective cooling can do the same job that evaporative cooling can do.

In fact, it is the TOA energy balance which takes primacy in many climate change discussions (there are some exceptions, such as if you could introduce a moist surface in the Sahara desert, the evaporative cooling would likely be more important regionally than CO2 increase).

The contribution of reduction in evaporative cooling to higher surface air temperatures during drought.

The liquid condensed at the bottom evaporates creating local cooling and rises; the way ocean water and all water does from the surface as an enormous pool of evaporative phase change refrigerant for the surface (and the atmospheric bath of nitrogen / oxygen).

How are they gonna stop convective / evaporative cooling of the Earth's surface?

I'm always aware that evaporative and convective cooling near the surface is contributing to the heating of the atmosphere; but do tend to push it aside, to concentrate on what the purely EM radiative effects are.

H2O — said to be the most potent «greenhouse gas» — doesn't cause warming in the open atmosphere; rather it drops the temperature of surface level air; it acts like an evaporative cooler (commonly called a «swamp cooler») rather than a greenhouse.

Why would they try to minimize evaporative cooling at the surface while nearly maximizing it at the walls by use of uninsulated canvas?

Some of the surface cooling would be caused by an increase in evaporative cooling due to the higher trade winds, but the vast majority of the surface cooling is caused by the upward shift in the thermocline, which is also related to the increase in trade winds.

If CO2 is heating the oceans it should show up in the near surface waters and result in a shift to greater evaporative cooling.

Indeed, the density buildup from salt excess and evaporative cooling is what causes the North Atlantic surface waters to sink so dramatically.

There is evaporative cooling which is increased with surface winds, aka velocity pressure that also can do the «filling».

Question is, how much heat is removed from the surface by radiation, air convection and evaporative cooling.

Back radiation does not slow evaporative cooling of a warmer water body, or slow the rate of conduction into air molecules at the surface - atmosphere boundary.

D Cotton June 15, 2013 at 6:38 am The whole of the pseudo physics of greenhouse effects and assumed heating of the surface by back radiation (or «radiative forcing») is trying to utilise the Stefan - Boltzmann equation which only relates to bodies in a vacuum losing all their energy by radiation without any conduction or evaporative cooling.

At the surface, the solar heating — net LW cooling = net radiative surface heating = convective cooling = sum of sensible and latent (evaporative) cooling.

(In the full 4 - dimensional climate, in some places and times and weather conditions, there will be sensible heat transfer toward the surface; there can be latent heat transfer to the surface as well (frost / dew); some places will have evaporative surface cooling with sensible surface heating (cold dry air blowing over warm water or a warm moist surface).

In fact the shortwave energy absorbed during the tropical summer at depth remains there until the winter when the humidity falls enough so that evaporative cooling sets up strong enough vertical convection to overcome the shallow diurnal reversals in the topmost one to three meters and dredge those deeper waters up to surface where some more rapid cooling can take place.

Surely, for example, it's a no - brainer to maximise foliage in mid-latitude cities (e.g. London) to keep the surface cool in summer, through the provision of shade and evaporative cooling (transpiration).

Last, the combined respiration of the plants in the greenhouse - collectively an enormous evaporative surface - cools the air and helps to reduce the «heat island effect» created by the typical black tar roof.

Evaporative cooling is so powerful it creates an «S» shaped curve because it draws more energy out than can be pushed back to the surface through the natural rising of heat below the surface.

But I do not see any simple way to verify the no - feedback sensitivity; if you include evaporative cooling from the ocean surface (for example), then you immediately get into the feed - back issues of water vapor and cloud cover.

In these cases, the prevailing dry conditions set the stage for the heat since the land is dried out, the vegetation is wilted, and all of the heat from the sun goes into raising temperatures, whereas ordinarily, in the process of evaporative cooling, surface water or wetness acts as an evaporative cooler (swamp cooler) of sorts.

To use this same system for cooling, the north side of the Solar Shed roof is set up as a evaporative / radiation cooling surface.
