-LSB-... * Salinity in the sea fell sharply during the Permian for the first time, changing oceanic physics to make deep
water circulation more difficult.

This seems like it's going to keep tropical
waters hotter and thus promote
more hurricanes (in agreement with what Gray says (if one interprets his statements as referring to the portion of the atlantic
circulation — the subtropical gyre — that delivers
more warm
water to the tropics).
In particular, I won't be surprised if continued decade - to - decade variability in atmospheric
circulation results in
more, and less, intrusion of circumpolar deep
water onto the continental shelf, and to
more, and less, rapid thinning of ice shelves in West Antarctica *.
As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even
more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no
water circulation takes place, which is precisely the case in permafrost where by definition the
water is frozen.
Partly this has to do with changes in ocean
circulation taking warmer
water deeper and partly as the result of the southern hemisphere having less land mass and
more ocean — where the ocean has a higher thermal inertia, meaning that it takes longer for those
waters to warm.
Another possibility might be a slowing of deep
circulation (not sure how much there is, mind), in which case the opposite occurs, and the surface
waters heat up even faster, leading to yet
more rapid surface melt, smaller winter ice volumes and so on.
The undetected «threshold» scenario that I posed in # 11 could be
more generally characterized as a shift in the thermo - haline
circulation (THC) caused by an emergent new source region for deep
water formation.
It is known that there is a pronounced difference in Hadley cell
circulation between winter and summer, heat spreading
more evenly would mean greater
water vapor density, exacerbating AGW effects a great deal
more.
Ultimately if the freshwater melt was a dominant (which seems hard to believe given the scale of the wind - driven gyre transport) factor, it would be entrained into the gyres at the surface and you'd see an overall freshening of North Atlantic surface
waters to make the whole system
more like the Pacific, which has a much weaker meridional overturning
circulation.
The Guardian says: «the Atlantic Meridional Overturning
Circulation (Amoc), has weakened by 15 % since 1950, thanks to melting Greenland ice and ocean warming making sea
water less dense and
more buoyant.
So while the monsoon winds might weaken the precipitation nonetheless increases (
more bang for the buck) as a weaker
circulation carries
more water vapor (and latent energy).
Higher modelled temperature in the troposphere enables the general
circulation model to assume there is
more water vapour in the troposphere which amplifies the CO2 forcing by increasing the amount of
water vapor in troposphere.
The vertically integrated inventory of human emitted CO2 in the oceans is (not surprisingly) much greater in areas of cold deep convection, especially in the northern Atlantic (the falling leg of the thermohaline
circulation), and much less in the tropics where the ocean is strongly stratified; absorption in the tropics really is
more in the near - surface
waters.
When the tropical easterly trade winds strengthen, as they have from the year 2000 onwards, this whole wind - driven ocean
circulation becomes
more vigorous, the South Pacific subtropical gyre spins up, and the western arm of the gyre exports
more tropical
water through the Indonesian archipelago into the Indian Ocean.
Some of the warm
water would be subducted by Atlantic Meridional Overturning
Circulation / Thermohaline
Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed
more by the effects of the slower - than - normal trade winds.
It releases
more than it absorbs because of ocean conveyor belt
circulation pulling in tropically warmed
water.
Through horizontal averaging, variations of
water vapor and temperature that are related to the horizontal transport by the large - scale
circulation will be largely removed, and thus the
water vapor and temperature relationship obtained is
more indicative of the property of moist convection, and is thus
more relevant to the issue of
water vapor feedback in global warming.
The tropical cyclones that bend northwards, move across this warm
water, that adds
more vertical convection power and moisture to the weather system — that can then turn into a closed
circulation hurricane.
It would explain a lot
more if there were variations in the
water temperatures coming from the oceanic
circulations BEFORE they became involved in the ENSO process.
This is due to several ACD - linked factors, including warming
water (which expands as it warms),
more severe storms and a stronger Atlantic meridional overturning
circulation, on which Truthout previously reported in detail.
and «It would explain a lot
more if there were variations in the
water temperatures coming from the oceanic
circulations BEFORE they became involved in the ENSO process.
The
water cycle assists stabilisation of top of atmosphere energy balance and reduces the need for a
more vigorous
circulation.
Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and
water they discharge into the ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean
circulation and regional weather patterns.7 (See Greenland ice sheet hotspot for
more information.)
In the Atlantic Ocean, the Gulf Stream is part of what's called the Atlantic Meridional Overturning
Circulation, a conveyor belt of ocean
water that carries warm
water from Florida to Greenland where it cools and sinks to 1000 meters or
more before traveling back down the coast to the tropics.
«Relatively cool
waters in the eastern Pacific often result in stubborn summer high - pressure systems over the eastern states that block storms, reducing the frequency of precipitation below normal,» noted study co-author Richard Healy of the Woods Hole Oceanographic Institution, Woods Hole, Mass. «Less frequent storms result in higher surface and atmospheric temperatures that then feedback on the atmospheric
circulation to further reduce storm frequency and raise surface temperatures even
more.»
Weyl (1968), speculating that the «temporary stagnation» of the bottom
water would end because of warming by the interior heat of the Earth; the role of glacial meltwater suppressing North Atlantic Deep Water production was also pioneered by Worthington (1968); a neat explanation of the entire circulation in terms of water evaporating from the North Atlantic more than from the cooler North Pacific was indicated by Warren (1

In addition to the main threshold for a complete breakdown of the
circulation, other thresholds may exist that involve
more - limited changes, such as a cessation or diminishment of Labrador Sea deep
water formation (Wood et al., 1999).
While a surge in heavy, salty
water can invigorate deep
water circulation, a dilution of the
waters prompts a
more lethargic flow.
«Salt plays a far
more important role that we first thought,» says Rainer Zahn, a palaeoclimatologist at the Autonomous University of Barcelona in Spain.Zahn and his colleagues found that a build up of salty
water off the coast of South Africa could jump start ocean
circulation in the North Atlantic (this despite the two regions being thousands of kilometers apart) while a reduction in the South African
waters» saltiness could cause the opposite effect.
Adding
more Co2 will either increase this process slightly (the Walker
circulation) or limit
water vapor's presence in the upper troposphere by radiational cooling.
More recently, there was a proposal to dam the Straits of Gibraltar in order to prevent more saline Mediterranean Sea water (because of the Aswan Dam) from affecting the North Atlantic conveyor circulation (no, it didn't make sense to us eith
