Panting allows evaporation of water and heat across the moist surfaces of the lungs, tongue, and surfaces within the mouth.

This can be tricky, and most keepers opt for a combo of a large water bowl to provide the surface area for evaporation, and misting the lizard several times a day.

The model considers all relevant feedback processes caused by changes of water vapour, lapse - rate, surface albedo or convection and evaporation.

Oil on the surface of water would retard its evaporation.

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-.

While it is true that infrared is absorbed in a thin skin at the top of the water, even if the water were completely quiescent this would still lead to the skin layer heating up until emission (plus evaporation and all the other terms we include in the surface budget) equalled the energy input.

(I think that an anomalously warm ocean surface heated from below would lead to more evaporation, and the additional water vapor would give a positive greenhouse effect that would partially offset the effect of a drop in greenhouse gas concentrations.)

The sinking is mainly driven by the saltiness of the water, which is affected by evaporation of fresh water from the surface or, particularly in the Arctic, freezing seawater which leaves salt behind in the water beneath the ice.

... At sea surface temperatures above 80 Fahrenheit (27 C), evaporation loads the atmosphere with a critical amount of water vapor... a controlling factor seems to keep the same thing from happening on Earth.

The increased area of warm water on the surface allows the tropical Pacific Ocean to discharge more heat than normal into the atmosphere through evaporation.

An increase in surface temp will increase water vapor pressure at the surface: that will likely increase the rate of evaporation at the surface, which may or may not increase cloud cover.

This occurs in a similar way as the earth's surface energy budget compensates for half its solar gain of 171 Wm - 2 by surface to air upward water vapor flux due to evaporation.

There is a very important phenomenon which occurs in the boundary layer of the surface of the water for evaporation occurs, where water evaporates and the layer in the atmosphere.

Only in certain regions, notably in the Antarctic and northwest Atlantic Oceans, does a combination of evaporation (which increases the water's salt content) and wintertime cooling make surface water dense enough to sink all the way down.

Six types of instruments aboard Aqua are to scan through the atmosphere down to the surface, gathering the most detailed data ever on water vapor in clouds, ice crystals in the air, evaporation, water in the oceans, icebergs and other sea ice, as well as glaciers and snow pack on land.

evapotranspiration loss of water from the soil both by evaporation from the surface and transpiration from the plants growing thereon

The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

Part way there, but no quantitation yet: of the 3.77 W / m ^ 2 radiated back dowwnard, most goes to increased rate of evaporation of the water at the surface, and much less goes to increased mean temp increase at the surface; hence increased rate of non-radiative transfer of heat from surface to upper atmosphere, slight increase in rainfall as hydrological cycle is faster, and slight increase in cloud cover.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

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).

Trapping billions of gallons a day out of the evaporation cycle or putting films on the surface also slows the evaporation by blocking water being on the surface.
