Evaporation dissipates
heat as water vapor and therefore cools your pet.
Not exact matches
At high
heat, the cladding interacts with the surrounding
water vapor, binding tightly to the oxygen and freeing the hydrogen, which escapes
as a gas.
The so - called greenhouse gases — mainly
water vapor and carbon dioxide — make the planet warm and habitable by trapping solar
heat as it radiates back off the Earth.
In the morning, the chamber is closed, and sunlight entering through a window on top of the device then
heats up the MOF, which liberates the
water droplets and drives them —
as vapor — toward the cooler condenser.
The
heat absorbed by
water vapor and carbon dioxide is shared with all the nitrogen, oxygen and argon, because the latter molecules are always bumping into
water vapor and carbon dioxide
as they mix in the atmosphere.
The impactor's kinetic energy is transformed into
heat, which melts the permafrost, releasing methane and
water vapor and expanding the size of the resulting crater by
as much
as a quarter.
Evaporation requires energy, and the
water vapor then stored that energy
as heat in the atmosphere.
Consequently,
as water evaporates, the
vapor carries
heat away from the
water.
To
heat that boiler, the damp, crumbly brown coal known
as lignite — which is even more polluting than the harder black anthracite variety — burns in the presence of pure oxygen, a process known
as oxyfuel, releasing
as waste both
water vapor and that more notorious greenhouse gas, carbon dioxide (CO2).
The research, published yesterday in Nature Climate Change, outlines a counterintuitive side effect of climate change:
As higher temperatures drive plants and trees into areas now inhospitable to them, their new distribution speeds up temperature rise via natural processes such as releases of heat - trapping water vapor into the ai
As higher temperatures drive plants and trees into areas now inhospitable to them, their new distribution speeds up temperature rise via natural processes such
as releases of heat - trapping water vapor into the ai
as releases of
heat - trapping
water vapor into the air.
As tides raised by Jupiter in Europa's ocean rise and fall, they may cause cracking, additional
heating, and even venting of
water vapor into the airless sky above Europa's icy surface.
Scientists believe that
heat brings up
water vapor from the inside of the planet, which condenses
as it rises and produces
heat.
Increased
water vapor is expected to accompany increases in temperature (IPCC 2013), and
as a result
heat stress increases are compounded.
Then,
as the bulb
heats the lamp, the
water vapor is released back into the air, but the rock salt lamp retains the contaminants.
That is the main source of more
water vapor and energy (
as latent
heat) in the air, and consequently weather trouble.
(PS regarding Venus —
as I have understood it, a runaway
water vapor feedback would have occured when solar
heating increasing to become greater than a limiting OLR value (Simpson - Kombayashi - Ingersoll limit — see http://chriscolose.wordpress.com/2010/08/23/climate-feedbacks-part-1/ — although I should add that at more «moderate» temperatures (warmer than today), stratospheric H2O increases to a point where H escape to space becomes a significant H2O sink — if that stage worked fast enough relative to solar brightening, a runaway H2O case could be prevented, and it would be a dry (er)
heat.
So
as more CO2 gets pumped into the atmosphere the temperature rises, which causes more
water to evaporate (
as you accurately state), increasing the concentration of
water vapor in the atmosphere — which
heats the atmosphere even more, causing even more
water vapor to enter the atmosphere.
The surface
heat capacity C (j = 0) was set to the equivalent of a global layer of
water 50 m deep (which would be a layer ~ 70 m thick over the oceans) plus 70 % of the atmosphere, the latent
heat of vaporization corresponding to a 20 % increase in
water vapor per 3 K warming (linearized for current conditions), and a little land surface; expressed
as W * yr per m ^ 2 * K (a convenient unit), I got about 7.093.
@zebra I think the extreme weather factor is all about the increasing lower - tropospheric
water vapor content, which plays out in storms
as a latent
heat issue.
But then there's feedbacks within the stratosphere (
water vapor), which would increase the stratospheric
heating by upward radiation from below,
as well
as add some feedback to the downward flux at TRPP that the upward flux at TRPP would have to respond to via warming below TRPP.
So a local spike in precipitation releases a lot of
heat — but
as the
heat increases, this negatively affects the
vapor - >
water transition (precipitation, or raindrop formation), since warm air holds more
water then cool air — and so the limit on precipitation vis - a-vis the radiative balance of the atmosphere appears.
The atmosphere and surface might very well
heat up from enhanced GHE, but
as soon
as water vapor feedback kicks in it will actually act
as both a positive and a negative feedback.
(In the global time average, diffusion of latent
heat is in the same direction
as sensible
heat transport, but latent
heat will tend to flow from higher to lower concentrations of
water vapor (or equilibrium
vapor pressure at the liquid / solid
water surface), and regionally / locally, conditions can arise where the latent
heat and sensible
heat fluxes are oppositely directed.)
Yes —
water vapor traps 1000 times
as much
heat as CO2.
Note also that under hot conditions a stream of
water vapor may not form clouds, but will instead act
as an infrared blanket that amplifies the
heat wave (this kind of
heat wave is seen in California, fed by marine moisture from Baja).
Re 9 wili — I know of a paper suggesting,
as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like
water vapor and, if positive, clouds, though regional changes in
water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the
heat capacity of the sea prevents much temperature response, but there is a greater build up of
heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
Is less poleward transport of
heat by the Gulf Stream
as the AMOC weakens a positive feedback for global warming, since that energy will escape more slowly in the humid (higher
water vapor GHG effect) tropics than near the poles?
The thermodynamics of
water are simplified in that only the
vapor - liquid phase transition is taken into account, and the latent
heat of vaporization is taken to be constant,
as in Frierson et al. (2006).
The
heat caused by infrared radiation is absorbed by greenhouse gases such
as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere.
Too much CO2 could even cool it, due to increased proportions of CO2 which is less effective than
water vapor as a
heat - trapping gas.
Disputes within climate science concern the nature and magnitude of feedback processes involving clouds and
water vapor, uncertainties about the rate at which the oceans take up
heat and carbon dioxide, the effects of air pollution, and the nature and importance of climate change effects such
as rising sea level, increasing acidity of the ocean, and the incidence of weather hazards such
as floods, droughts, storms, and
heat waves.
Basically Miskolczi has looked at the thermodynamics of
water vapor and CO2 and found that they interact such that,
as CO2 rises, absolute humidity decreases, creating a relatively constant
heat - trapping effect, if not a decreased effect with an increasing proportion of CO2.
As a «thought experiment», the critical
heating role for
water vapor droplets and CO2 concentrations lacks real - world validation.
He was the first to measure that certain gases, such
as carbon dioxide (CO2) and
water vapor (H2O), trap
heat in our atmosphere.
The adiabatic theory would hold that CO2 actually acts
as a coolant to the atmosphere, by trapping
heat and carrying up to TOA to be released,... just
as the other well known GHG,
water vapor, does.
A thunderstorm event might be best depicted
as a run - away rising column of air that is becoming progressively warmer than the surrounding air
as condensing
water vapor yields its
heat of vaporization until almost all
water vapor has condensed out and then cooling at a rate of 9.8 deg C per 1000 meters, it eventually reaches a warmer layer of air and spreads out like smoke over a ceiling.
These algorithms, developed for national and international operational and research satellite programs, convert sensor / instrument measurements into geophysical parameters such
as vertical temperature /

as sea surface winds, net
heat flux, and forest fire intensity / extent.
They also measured the latent
heat released over land
as the
water vapor turned back into liquid
water and fell
as rain.
Fact: an increase in
heat equals an increase in
water vapor and
as a result clouds.
And, since CO2 is not
as strong a
heat - trapping gas
as water vapor, then rising CO2 could slightly cool the climate.
Latent
heat is in the air when there's
water vapor in the air, 2260 kiloJoules for each kilogram,
as a matter of fact.
GREENHOUSE EFFECT Greenhouse gases in the atmosphere (such
as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which
heats the lower atmosphere.
AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take
water vapor scavenged from the vast oceans on earth (which are also a formidable
heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of
heat from the atmosphere) or freeze it, (removing even more vast amounts of
heat from the atmosphere) drop it on land and oceans
as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing
water mass from equatorial latitudes and transporting this
water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..
When the convective processes of the atmosphere remove enough
water vapor from the oceans to drop sea levels and build polar ice caps,
as has happened many times before, the top 35 meters of the oceans where climate models assume the only thermal mixing occurs, must
heat up cold ocean
water that comes from depths below the original 35 meter depth, removing vast more amounts of
heat from the earth's surface and atmosphere.
As if sweltering heat weren't bad enough, Europeans also suffered through a higher - than - normal number of days with dangerous smog levels that year.6 Smog — with ground - level ozone as the main component — forms when sunlight reacts with chemicals such as volatile organic compounds, carbon monoxide, nitrogen oxides, and water vapo

as much IR,
heat energy, from sunlight
as water vapor which has 188 times
as many molecules capturing 1200 times
as much
heat making 99.9 % of all «global warming.»
But even if it doesn't increase at all (the more likely situation), that won't stop the
heating effect of increasing CO2, even if there's a thousand times
as much
water vapor as CO2.
This is why gardeners will put
water vapor in the air and
water liquid on the ground around their garden on a clear cold night — it protects the local area from cooling
as fast because
water vapor and liquid both 1) cool much slower than dry air due to their massive
heat capacity, and 2) cool even slower because they release their massive latent
heat, which means that
heat energy is released from them without requiring a drop in temperature — once they're in the latent
heat release phase, they just keep shedding energy without dropping in temperature any further.
the greenhouse effect is an increase in the average temperature of the earth «Greenhouse gases» such
as water vapor, carbon dioxide, ozone and methane, slow the escape of
heat from earth's atmosphere.
As for your V&V discussion, I don't see the relevance of it in this talk, but in the context of physical science of climate change we have overwhelming evidence of model usefulness and verification (
water vapor feedback, simulating the Pinatubo eruption effects, ocean
heat content changes, stratospheric cooling, arctic amplification, etc).
