This is accomplished with a powerful blast of
warm air that quickly breaks
up the layer of
surface water on a userâ $ ™ s hands for quick removal and evaporation.
The only major potential drawback of baby wipe
warmers is the simple fact that they are a piece of electrical equipment that heats
up and is often in close contact to
water and wet
surfaces.
However, in their wake, hurricanes set
up large - amplitude waves that mingle
warm surface water with colder deep
water, says climate scientist Matthew Huber of Purdue University.
Chan says that lighter
warm water creates a cap over the colder depths, making it less likely that deeper
waters — where everything from «plankton to whale poop» sucks
up oxygen — will rise to mix with the oxygenated
surface.
Heat that stays at the
surface will ultimately result in greater sea - level rise as
warmer water expands more readily as it heats
up.
So, for example, a big part of what drives a hurricane is the fact that you've got a lot of
warm water near the
surface of the ocean that is transferring heat into the air, and that's what's moving
up, and that is a big part of then what's propelling the entire bigger storm system.
About 19 months after the wind churned the ocean, cycling
warm deep
waters upward and sending the cold
surface waters down, the Totten ice shelf was noticeably thinner and had sped
up.
«During Norwegian winters, sea
surface water is colder than at depth, so by lifting
warmer water to the
surface using bubble curtains, we can prevent the fjords from icing
up», he says.
Furthermore, a deeper upper layer of
warm surface water may weaken the cold tongue if the Ekman pumping doesn't reach down below the thermocline to bring
up colder
water, and weakened trade winds would have a similar effect through reduced Ekman pumping near the equator.
With the removal of the
warm surface waters, an upwelling current is created in the east Pacific Ocean, bringing cold
water up from deeper levels.
During normal conditions, trade winds blow to the west across the tropical Pacific Ocean, piling
up warm surface water in the western Pacific, and cold, deeper
water rises
up, or upwells, off the west coast of South America.
These strong, constant winds push and drag the
warm surface water westward, «piling» it
up and holding it in the western Pacific Ocean basin.
The CO2 concentration of the atmosphere is going
up continuously, and so it invades the ocean as it equilibrates with
warm surface waters.
Think of what would happen if you could pump cold deep
water up to the
surface, increasing the air / sea temperature gradient and
warming the
water; that would give you an anomalously large ocean heat uptake.
2 — previously
warm saline
surface water, now wind cooled (cold) saline
surface water sinks to depths
up to 2000m.
Furthermore, a deeper upper layer of
warm surface water may weaken the cold tongue if the Ekman pumping doesn't reach down below the thermocline to bring
up colder
water, and weakened trade winds would have a similar effect through reduced Ekman pumping near the equator.
Normally, a hurricane sucks
up cold
water from deeper layers, cooling the sea
surface and weakening the hurricane, but in the case of deep
warm water layers, the hurricane intensifies because it is sucking
up warm water.
Independent computer models (about 23 or so world - wide, I believe), generally show a
warming of the
surface and even more in the tropsophere in the tropics due to increased
water vapor (
warm the air
up and it has more available
water vapor (a greenhouse gas)..
Water at the
surface that is below the equilibrium temperature will be
warmed mainly radiatively until it
warms up again.
I recall mention that Katrina was unusual because while crossing the Gulf «Ring Current» the deeper
water pulled
up by the hurricane was almost as
warm as the sea
surface, so the deeper
water fed almost as much heat energy into the storm as the
surface.
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).
The real problem here is that this AMO explanation was picked
up and broadcast by the press in a very uncritical manner, usually in these terms: «
Surface waters of the Atlantic ocean
warm up then cool down in long, subtle cycles.
The ocean's
surface begins to
warm, but before it can heat
up much, the
surface water is mixed down and replaced by colder
water from below.
Hurricanes stirr
up the sea (mixing or Ekman pumping), and if there is a thin
warm surface layer, colder
water underneath will be brought
up, and hence give rise to lower
surface temperatures (SST).
Would the incoming insolation go to
warming up the
waters surface (and shading the depths) or would it go to converting H2O and CO2 to sugar?
The decade - long analysis showed that as the
surface water of the oceans
warmed up, phytoplankton biomass declined.
We also know that while the ocean
surface wasn't anomalously
warm (it was still about 30 °C which is fairly normal for that part of the planet), the
water up to at least 100 meters bellow the
surface was 4 — 5 °C (7 — 9 °F)
warmer than average.
All the sea
surface water,
warmed by the tropical sun, is blown to the west of the Pacific and, to compensate part of the imbalance, cooler deep ocean
waters well
up on the western shores of Latin America (and spread all the way
up to the Solomon Islands).
Most interesting is that the about monthly variations correlate with the lunar phases (peak on full moon) The Helsinki Background measurements 1935 The first background measurements in history; sampling data in vertical profile every 50 - 100m

Water takes longer to heat
up and cool down than does the air or land, so ocean
warming is considered to be a better indicator of global
warming than measurements of global atmospheric temperatures at the Earth's
surface.
Even if ALL the OCEAN ICE around the POLAR REGIONS does «melt», the newly
warmed sub-artic regions, verdant with streams and rivers, will take
up much of the release to increase the proportion of FRESH LIQUID
water available on a now EXTENDED verdant land
surface.
Then some mysterious combination of flagging trades, QBO, and the
up and downwelling effects of Rossby and Kelvin waves sloshing back and forth across the Pacific; suddenly releases this mechanically submerged
warm water eastward across the Pacific ocean
surface.
Um... while the oceans as a whole would have to cool, the sea
surface would have to
warm up substantially in order to transfer lots of heat to the air (and in order to
warm up substantially, I suppose there would have to be reduced circulation with cold deeper
waters).
«once you remove a large heat flow, for example by letting all the
water boil away, the
surface heats
up» So, Eli is saying, if absorptive material is added (to the atmosphere) the
surface cools; if absorptive material is removed, the
surface warms.
If ocean oscillations are as powerful a climate driver as the anti-CO2 alarmists claim then this graph suggests a simple story: that cold Pacific
surface waters swallowed
up a big gulp of warmth from 1940 - 1970, which the PDO then belched back
up during its
warm - phase in the 80s and 90s.
Stronger easterlies in the Pacific spin
up the gyres in both hemispheres and Ekman pumping in those regions intensifies, bringing
warmer surface waters to depth.
Global
surface temperatures in the last few years have received a bump in recent years because of a large El Niñ0 event, which brought
warm water up from the depths of the Pacific ocean and released the energy into the 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..
Vaporization rate increases with vapor pressure, so that as the
surface temperature
warms up, increasingly large amounts of energy are transferred to
water vapor instead of more temperature increase — and that leads in turn to more clouds (blocking the sun and transferring energy to the upper troposphere) and rainfall.
Harvey's rapid intensification from a tropical depression to an 85 - mile - per - hour hurricane in less than 24 hours was due to favorable conditions —
warm water and low wind shear [29]-- in the Gulf of Mexico, where sea
surface temperatures were
up to 2.7 - 7.2 °F (1.5 - 4 °C) above the 1961 - 1990 average.
Despite higher than normal
surface temperatures and heat contents of ocean
waters where the storms developed, evidence is lacking that global
warming is revving them
up.
But as they grow, their strong winds often pick
up seawater, churning the oceans and moving the
warmest waters deep below the
surface.
The hurricane churned
up water 100 or even 200 meters below the
surface, said Trenberth, but this
water was still
warm — meaning that the storm could keep growing and strengthening.
Because only very cold
surface water is able to sink, it is simple to understand that the deep ocean can never
warm up, regardless of how
warm the
surface ocean around the world may become.
So if on shined that laser on a square meter for say 10 mins then the 1 mm depth of square meter could
warm by about 1 C. Rather than
water one could also heat
up anything with a thin
surface [and assuming one reduces the heat loss] So thin sheet of paper which absorbs [has heat capacity of whatever wavelength one is using could heated within mins of exposure.
2] here is why US was WET, WET, WET: before Gibraltar straights and the English Chanel opened — there was no «Gulf - stream» Now, as soon as the
surface water in the Mexican gulf
warms up — GOES east,, as on a convayer - belt — no time to produce enough moisture in the air.
When ENSO is in La Niña, the Pacific trade winds blow true and strong causing sun
warmed surface water to pile
up against Australia and Indonesia.
ENSO (El Niño Southern Oscillation) variability is linked to the spinning
up or down of the South Pacific gyre — as it brings more or less cold Southern Ocean
water northward — along the Peruvian coast — to more or less displace
warm surface water and initiate upwelling.
