In fact much heat is taken from the lungs by panting - you see the condensation dripping from their tongues - because evaporation is the primary method of cooling whether through sweating or panting.

Instead, dogs cool their bodies using the evaporation of moisture from the mouth and tongue, and by exchanging the hot air of their lungs with cooler external air.

The layer will also gradually increase its humidity by evaporation of the ocean or lake surface, as well as by the effect of cooling itself.

The argument isn't actually as firm a constraint as generally believed, since the infrared radiative cooling of the atmosphere is affected by the temperature difference between air and the underlying surface, which can adjust to accommodate any amount of evaporation Nature wants to dump into the atmosphere (as shown in Pierrehumbert 1999 («Subtropical water vapor...» available here)-RRB-.

CO % 3B2 I would expect that eruptions that cause more cooling, which slow the evaporation / rainfall cycle, would lengthen the time for the aerosol concentration to drop by 1 / e.

While the energy input allows more evaporation to occur, it's confusing the matter to say that this «cools» the surface, since the evaporation is just helping to carry away the heat put in by the other terms.

The warm, open water gives off a great deal of water vapor by evaporation; the moisture is swept south and overland by the winds where it cools off and falls as rain or snow.

Evaporation of water in the cooling pad cools the air, dropping the temperature by as much as 25 F.

They provide cooling benefits by shading buildings and through evaporation from leaves.

P.s. Myrrh is correct on some things 100 %, on others he is wrong, for example: «water evaporation cools the land and the sea, BUT, that doesn't cool the planet — only takes heat high up to be easier cooled by the shuttling oxygen & nitrogen, plus: as sun umbrellas clouds intercept lots of heat, high up — nevertheless, that heat is still in the earth's system — only O&N are» COOLING THE PLANET» Petra, do you believe that; O&N exist in the atmosphere?

Were the winds to reduce tropical evaporation by one - third in a year, you'd see an abrupt shift from warm - and - wet to cool - and - dry.

The basic ocean cycle goes like this; in the summer brine is concentrated by evaporation and in the winter the dense brine cools and becomes still denser and sinks.

«86 % of the global evaporation occurs from the oceans, reducing their temperature by evaporative cooling.

Earth's surface is cooled mostly by non-radiative processes (convection, evaporation).

In this case, IR active gases are rather responsible for cooling the surface by clouds and evaporation.

Wet soil will release water by evaporation and cool the soil due to the heat required for that as latent heat.

Any increase in the temperature of liquid water is also likely to be transitory but may involve long timespans — besides it is likely to result in increased evaporation which is a very effective cooling mechanism as we animals demonstrate by our cooling mechanism — sweat.

The natural temperature control reduces the heat by up to seven degrees in the summer (relative to outside temperatures), due to cooling effects of evaporation, resulting in more stress - free chickens!

If water vapour feedback was positive then due to the increased evaporation spurred on by the original warming in the MWP there should have ensued a period of elevated temperatures for thousands of years until the cooling of the Holocene as we dip into the next glacial period overwhelmed the positive water vapour forcing.

[26] as the solar infrared radiation at 2.5 µm and 4.3 µm are slightly more absorbed by the «doubled» stratospheric CO2 (about 0.4 W / m ² as 24 hours average) the required additional cooling of the surface by evaporation will be only 0.4 W / m ²

Hence all the radiative - convective «models» since Manabe (1967) which assume a «radiative cooling of the surface» and forget evaporation are baseless: 71 % of the surface of globe is covered by oceans, and an additional 20 % of the surface covered by vegetation, driving evapotranspiration.

It is not the infrared emission that cools the surface as in the so - called radiative equilibrium models because the net radiative heat transfer surface to air is about nil, but the evaporation whose thermostatic effect can not be overstated: increasing the surface temperature by +1 °C increases the evaporation by 6 %; where evaporation is 100 W / m ², this removes an additional 6 W / m ² from the surface.

Since latent heat transport (and surface cooling of the ocean) must increase in proportion to the rate of evaporation, perhaps Wentz et al have identified a reason why the models appear to overstate climate sensitivity: the actual latent cooling increases by about 4 watts per square meter more than the models predict for each degree rise in surface temperature.

If that cooler 1 mm layer is indeed caused by evaporation drawing energy away upwards then more evaporation should logically cause more cooling of the ocean bulk not less.

Could an increase in greenhouse gases actually have a cooling effect over water by speeding up the rate of evaporation from the oceans thereby extracting energy faster from the oceans, speeding up the hydrological cycle and pushing energy faster to space?

It's odd that this seems to be inadequately dealt with by established science when the principle of evaporation being a net cooling process is so well known.

As per my posts above, it is possible for DLR to increase more than evaporation, and so the warming from the DLR beats the cooling from evaporation, leading to a warming whereby the system is moving towards equilibrium by increasing temperature and hence increasing sensible heat flux and emitted longwave radiation.

There is still a cooler layer that cools more if evaporation increases but now we see that the temperature measured by sensors is above that layer, is not part of it and therefore records a misleading warmth while the sub skin cools unnoticed as I said:

(NB: calling evaporation a «net cooling» process; the «net» is superfluous because evaporation by itself can cause cooling only!

Thus there is a temperature inversion caused in part by evaporation whereby energy is drawn out of the oceans faster than energy coming up from below plus solar shortwave entering into the cooler subskin layer.

f) all the additional energy coming from the increase of the back radiation is thermalized within the skin layer and then emitted back to the air by increasing radiation, convection, conduction and evaporation into the air so that none part of it is delivered to the ocean — otherwise it would give us the decrease of the cooling of the bulk temperature of the ocean;
