The rate of flow of
heat out of the ocean is determined by the temperature gradient in the «cool skin layer», which resides within the thin viscous surface layer of ocean that is in contact with the atmosphere.

Only the organized TCs take significant
heat out of the ocean ameliorating global warming of the oceans.
All other physical heat transfer mechanisms, conduction, latent heat of vaporization and radiation transfer
heat out of the ocean.
While 2016 was the warmest year on the surface, it was only the third warmest year for ocean heat content as the El Niño event that helped 2016 surface temperatures be so warm redistributed
heat out of the ocean and into the atmosphere.
Clouds are negative feedback driven nucleation points — when daytime clouds start to form the albedo causes further cooling beneath them and heat - engine thunderstorms form from the updrafts of warm wet air lofted up to the stratosphere to efficiently cool and spread, creating a local convective cell that pulls
heat out of the ocean (or the moist land or air) and moves it to a cold reservoir.
Not exact matches
The warming also indicates that a large amount
of heat is being taken up by the
ocean, demonstrating that the planet's energy budget has been pushed
out of balance.
So, in theory, if you could manage to lower the temperature
of the surface
of the
ocean ahead
of a hurricane by a few degrees, you could conceivably pull enough
heat out of the system that the storm would start to wind itself down.
As such, according to our calculations, the hope that the
ocean would someday run
out of heat won't pan
out in the long run,» Hellmer explains.
Is there a weatherman
out there willing to state that the
heat content
of the
oceans had no effect on the monsoon?
«The reason this study is so exciting is that previous methods
of reconstructing
ocean heat content have very large age uncertainties, [which] smooths
out the more subtle features
of the record,» said co-author Sarah Shackleton, a graduate student in the Severinghaus lab at Scripps.
The system began to be rolled
out in 2000, and by 2003 made up the majority
of ocean heat measurements.
So we can't usefully investigate the extent that atmospheric warming may have been driven by
heat transfers
out of the
oceans.
The top
of the curves are warmer years caused by El Niño; a weather phenomenon where the Pacific
Ocean gives
out heat thus warming the Earth.
Thus, during an El - Nino, much
of the
heat content
of the Indo - Pacific warm pool moves from being too deep for surface measurements to detect, to being spread
out on the surface
of the
ocean, where surface measurements can detect it.
Increased warming
of the cool skin layer (via increased greenhouse gases) lowers its temperature gradient (that is the temperature difference between the top and bottom
of the layer), and this reduces the rate at which
heat flows
out of the
ocean to the atmosphere.
The same concept applies to the cool skin layer - warm the top
of the layer and the gradient across it decreases, therefore reducing
heat flowing
out of the
ocean.
Adding further greenhouse gases to the atmosphere warms the
ocean cool skin layer, which in turn reduces the amount
of heat flowing
out of the
ocean.
Mantra Mooloolaba Beach looks
out across the
ocean and hinterland, and has the benefit
of two
heated pools and spas, a great recreation deck, multiple BBQ areas, along with a rooftop patio.
For about two years now, an atmospheric ridge
of high pressure in the northeastern Pacific has blocked
out storms and high winds, allowing the sun to
heat a 2,000 - mile stretch
of ocean stretching from the Gulf
of Alaska to Mexico.
Spend the time in between taking in the views
of St. Jean and the
ocean from a lounger on the sunny deck or the
heated pool that stretches
out in front
of the house.
This is to be expected because the spin - up
of the wind - driven
ocean circulation speeds up the currents (Ekman transport) which carry
heat out of the tropics in the near - surface layers toward the subtropical
ocean gyres.
By analogy, a warmer world wouldn't be rainier (or cloudier); it's an imperfect analogy, because rain isn't absolutely correlated with cloudiness, and lateral transport
of energy by

He plucks
out of context a sentence about OHC while ignoring the central argument we are making about that indicator — which is that if most
of the
heat is going into the
oceans and we now have substantially better ways to measure OHC then why not use that measure.
Because the drains
out of the various bathtubs involved in the climate — atmospheric concentrations, the
heat balance
of the surface and
oceans, ice sheet accumulations, and thermal expansion
of the
oceans — are small and slow, the emissions we generate in the next few decades will lead to changes that, on any time scale we can contemplate, are irreversible.
Also true is there exist
heat - tolerant corals, corals that are regularly exposed to (and routinely survive) the extreme stress
of finding themselves
out in the tropical air at low tide, and many
ocean organisms that live through large swings in pH through tidal cycles.
(I pointed
out in 231 that if all that
heat that makes up the increase in
ocean heat content since 2000 was in the atmosphere back in 1979, then it would have
heated up the atmosphere on the order
of 15 degrees C.)
What I mean by this is: When you plot
ocean heat uptake against climate sensitivity, I get the impression that the distribution
of good models will be a large clump around a climate sensitivity
of 3 but then there is a long tail
out towards higher sensitivities.
The second point is that we have found distinctive variations in global warming with El Niño: a mini global warming, in the sense
of a global temperature increase, occurs in the latter stages
of an El Niño event, as
heat comes
out of the
ocean and warms the atmosphere.
It was said above that the
ocean is warming just like the land (& air and ice sheets / glaciers), that the
heat in the
ocean dwarfs that in the land and air, that the warming is due to the net solar imbalance (solar in, less LW
out - no mention
of CO2.)
Gavin, I agree completely with the standard picture that you describe, but I don't agree with the claim that ``... as surface temperatures and the
ocean heat content are rising together, it almost certainly rules
out intrinsic variability
of the climate system as a major cause for the recent warming».
In equilibrium, all fluxes into the surface will be balanced by fluxes
out of the surface (including momentum, etc, as well as energy), so whatever lies beneath the surface gives the surface an effective
heat capacity and also (in the
oceans) some ability for local / regional imbalances to be balanced globally, with all
of that responding to forcings and PR+CR and other feedbacks at the surface.
Since the
heat capacity
of the land surface is so small compared to the
ocean, any significant imbalance in the planetary radiation budget (the solar in minus the longwave
out) must end up increasing the
heat content in the
ocean.
«Firstly, as surface temperatures and the
ocean heat content are rising together, it almost certainly rules
out intrinsic variability
of the climate system as a major cause for the recent warming»
Some people looked at parts
of that work (for example, the lower right panel
of Figure 1) and point
out how the climate model
oceans show a smooth and pretty much unbroken increase in
heat content over the historical period.
If tropical cyclone occurrence decreases, less
of the
heat is dissipated, and unless
ocean circulation in some way compensates by transporting the additional thermal energy elsewhere (i.e. for example
out of the «main development region»
of the Atlantic) some day a storm will tap the enhanced energy source.
For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying
out due to
heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake
of CO2 & releasing CO2 in the process) 3)
ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more
heat 6) the warming slowing the thermohaline
ocean conveyor & its up - churning
of nutrients — reducing marine plant life & that carbon sink.
Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions
of the Equitorial Pacific and the Indian
Ocean, strongly cooler in the nearest deep convection source region
of the South Atlantic near Africa and the Equator, warm over the bulk
of the North Atlantic, strongly warmer where the gulf stream loses the largest portion
of its
heat near 50N 25W, and strongly cooler near 45N 45W, which turns
out to be a back - eddy
of the Gulf Stream with increased transport
of cold water from the north whenever the Gulf Stream is running quickly.
These comparisons helpfully conveys the early stage
of understanding
of how a global shift, like the buildup
of heat - trapping gases and
heat in
oceans, plays
out in particular regions or types
of weather.
If in exceeds
out and the diffential MUST exist from top to bottom
of the atmosphere, then before the hotter air can migrate to the deep
ocean, the daily temerature cycling will force the hotter air at the bottom into an overall equlibrium ie hotter air will rise — or more correctly since GHGs have
heated the air up more at the bottom, then the sun induced daily warming will add more
heat to the top, & less at the bottom to force the equilibrium — ie effectively hot air rising even if not in actuality.
Second, energy in vs. energy
out of the system can hardly balance until we have a better handle on the circulation
of the
ocean (over 95 %
of the
heat capacity
of Earth) and its rate
of heat uptake.
Globally, the Ozzies have pointed
out that the
oceans have been busy absorbing almost all
of the
heat energy (90 %) The atmosphere and the land, including ice, store the other 10 %.
Consider the possibility that not just millions, but billions face disastrous consequences from the likes
of (including but not limited to): Sandy (and other hybrid and
out -
of - season storms enhanced by the earth's circulatory eccentricities and warmer
oceans); the drought in progress; wildfires; floods (just last week, Argentina had 16 inches
of rain in 2 hours *); derechos; increased cold and snow in the north as the Arctic melts and cracks up, breaking up the Arctic circulation and sending cold
out of what was previously largely a contained system, and losing its own consistent cold, seriously interfering with the Jet Stream, pollution
of multiple kinds such as in China, the increase
of algae and the like in our
oceans as they
heat, and food and water shortages.
Just recently a «scientist» at the German hyper alarmist PIK «found
out» that the (temporary) loss
of sea ice in the arctic leads to increased
ocean heat loss to the atmosphere resulting in more snow elsewhere.
Bob Tisdale says: January 10, 2011 at 3:05 pm Manfred says: «Just recently a «scientist» at the German hyper alarmist PIK «found

The effect it has on the equilibrium sensitivity is more indirect, as the more the
ocean can buffer excess
heat, the more chance it will give for CO2 to sequester
out of the system.
The amount
of extra
heat stored at the surface layer
of the
ocean wanting to get
out is cubed.
Nobody cares about milli - degree warming
of the vast, cold deep
ocean nor can such
heat move against a temperature gradient and come
out to bite us.
Apparently there are a lot
of people who seem to like that hippy commune style
of living, and feel free, don't let me stop you, but I want the Jetson's, I want humans to become a spacefaring race, we need to mine the asteroid belt, and someday travel to the stars, but in the mean while there are
oceans of liquid hydrocarbons (though not very practical as a home
heating fuel, I realize) and boulders
of platinum group metals
out there to go get.
Similarly, and as discussed here, Matthew England's recent discovery
of the «missing
heat» — right or wrong — in the
oceans followed years
of his somewhat angry criticisms
of climate sceptics rightly pointing
out the missing
heat, leading to their claims, rightly or wrongly that climate science had erred.
