Those weather patterns are linked to warmer surface temperatures in the Pacific and Atlantic oceans, respectively, and correlated with the timing of observed floods on the lower Mississippi.

The die - off is due to a combination of rising sea surface temperatures and decreased ocean circulation between the higher and lower layers, Boyce says.

The research, an analysis of sea salt sodium levels in mountain ice cores, finds that warming sea surface temperatures in the tropical Pacific Ocean have intensified the Aleutian Low pressure system that drives storm activity in the North Pacific.

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.

Note that we've got a paper soon to come out in «The Cryosphere» (and we'll have a poster at AGU) looking at recent «Arctic Amplification» that you discuss (the stronger rise in surface air temperatures over the Arctic Ocean compared to lower latitudes).

Because land surfaces generally have low heat capacity relative to oceans, temperature anomalies can vary greatly between months.

In March, 2018, lower tropospheric temperatures (1500m) over the oceans (71 % of the earth's surface) also saw a further drop:

There are some various proposed mechanisms to explain this that involve the surface energy balance (e.g., less coupling between the ground temperature and lower air temperature over land because of less potential for evaporation), and also lapse rate differences over ocean and land (see Joshi et al 2008, Climate Dynamics), as well as vegetation or cloud changes.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

Actually, I thought about it and having oceanic circulation does allow this behavior (that the surface temperature can decline when forcing is declining even while it is still less than the equilibrium temperature)-- it makes sense because the deep ocean may still be pulling the surface temperature toward a much lower temperature.

First, global mean surface temperature depends on the quantity of heat stored at the surface of the earth (earth, lower atmosphere, and the mixed layer of the oceans).

Global average air temperature near the surface is dominated by the ocean (because it covers two thirds of the planet), particularly at low latitudes.

Apparently, in the last decade or so, surface and lower troposphere temperature has risen more slowly than the long term trend, but ocean heat content to 2 km has risen faster than the previous two decades.

Others include, the role of the Sun (being the main heat source), the vast oceans which cover over 70 % of the Earth's surface (and the natural factors which determine the storage and release of CO2 back into the atmosphere), water - vapour being the dominant greenhouse gas comprising 98 % of the atmosphere, the important role of low - level clouds which is thought to be a major factor in determining the natural variation of climate temperatures (P.S. Significantly, computer - models are unable to replicate cloud - formation and coverage — which again — injects bias into model).

(1) The overall global temperature change sequence of events appears to be from 1) the ocean surface to 2) the land surface to 3) the lower troposphere.

High quality heat (5000K sunlight) is transformed into low quality heat (255K water) and it can never again be used to heat anything to a temperature higher than 255K which includes the ocean surface and the air above it.

And the lower troposphere temperatures also show warming in the Southern Ocean (latitudes 65S - 55S) while the surface temperature - based datasets both show cooling.

Let's compare the warming and cooling patterns for lower troposphere temperatures over the oceans to a spatially complete, satellite - enhanced sea surface temperature dataset, Reynolds OI.v2.

Since Trenbreth did not provide a mechanism for the heat to go from the atmosphere to the lower levels of the ocean, and since we are talking about the same amount of heat, that which would make the atmosphere not climb in temperature for 10 to 15 years, it is much much more reasonable to assume the heat went from the surface of the ocean to Trenbreth's depths (the ocean simply overturned).

While there are some similarities between the approaches, an important difference is that the slab - ocean approach allows surface and MBL temperatures to adjust to the energetic perturbation: positive energetic forcing of the surface leads to warming, weakens the inversion, and reduces low - cloud cover and liquid water path (LWP).

And for the period of 1997 to 2012, there are no similarities between the warming and cooling patterns for lower troposphere temperatures over the oceans and the satellite - enhanced sea surface temperature data.

I also suspect that a good portion of the additional warming shown in the hybrid version of the Cowtan and Way (2013) data (versus their Krig data) comes from the Southern Ocean surrounding Antarctica, where sea surface temperatures are cooling and lower troposphere temperatures are warming.

If the ocean was same temperature surface to sea bed it would be impossible to raise temperature of the lower part from above without raising the temperature of the upper part, but it ain't, so it is.

«this result would imply that all current attributions to solar variability of temperature changes in the lower atmosphere and surface ocean would be of the wrong sign.

By assuming that the absolute value of the «average» surface temperature common to both the atmosphere and oceans is 4 - 5 C lower than the actual, there would be considerable error wouldn't there?

The evolution of El Niño - Southern Oscillation (ENSO) variability can be characterized by various ocean - atmosphere feedbacks, for example, the influence of ENSO related sea surface temperature (SST) variability on the low - level wind and surface heat fluxes in the equatorial tropical Pacific, which in turn affects the evolution of the SST.

More generally, we are using multiple sensor & associated data sets (low frequency microwave radiometers, ocean color, sea surface temperature, wind, wave, altimeter products, model and in situ data..)

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.

El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fiocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fiOcean, having disastrous effects on marine life and fishing

It is most prominent in the North Pacific, where fluctuations in the strength of the winter Aleutian Low pressure system co-vary with North Pacific sea surface temperatures, and are linked to decadal variations in atmospheric circulation, sea surface temperatures and ocean circulation throughout the whole Pacific Basin.

Like all models, it has its quirks — an absolute surface temperature that's a bit too low, projections of ocean heat uptake that are a bit too high.

If there has been only a fairly small change in ocean heat flux over the last century and the ratio of global increase in surface temperature to increase in forcing is low (as the evidence certainly suggests), then it follows that climate sensitivity is low — perhaps of the order of 1.5 C.

It is notable that this feedback is arguably the most difficult to control due to the period of several decades that would be required to restore the upper oceans» natural temperature by an Albedo Restoration program lowering the surface air temperature.

Since you are a frequent visitor to WUWT, you are well aware that I have illustrated, explained, and animated cause (ENSO) and effect (the warming of sea surface temperatures, ocean heat content, lower troposphere temperatures, and land + sea surface temperatures) in dozens of blog posts over the past 3 1/2 years.

Hence, contrary to what you seem to be assuming, ocean surface temperature (together with lower tropospheric temperature) are * inversely * related to the rate of ocean heat gain.

When oceans get cold, and the surface of polar waters freezes, it snows much less and the sun takes away ice and limites the lower bound of temperature and sea level.

When the intensity of ultraviolet light from the sun increases, temperature rises in this ozone rich air and weakens the downdraft, lowers the surface pressure and with it the strength of the trade winds that blow across the ocean to the low pressure zones that form over the warm waters that accumulate in the west.

(Someone somewhere I saw recently, maybe in this thread estimated that if all the excess heat in the ocean were distributed to the lower atmosphere instead the global mean surface temperature would be 36 C warmer.

But worse is your paper with Nic Lewis, which seems to go out of its way to get a low ECS by purposely not using the best data available for surface temperatures, ocean heat content, and with no consideration of aerosols at all.

When heat stays nearer the ocean surface, forcing raises surface temperature faster than when more of the heat is distributed at lower depths.

These indicators include greenhouse gas concentrations, temperature of the lower and upper atmosphere, cloud cover, sea surface temperature, sea - level rise, ocean salinity, sea ice extent and snow cover.

Figure 15 - A has shown the global pacing by the El Niños (and their tele - connections) of the temperature changes of the lower troposphere as function of both time and latitude; this pacing may be due to the coming to the surface, at high latitudes, of warm water from the Pacific warm pool, as they move to higher latitudes on the western rim of the oceans after an El Niño.

I believe the lower bound is being made lower because of physics modeling that says that the ocean surface temperature will take forever to fully respond to the forcing.

My limited understanding is that if I take a temperature measurement at a ship on the Pacific Ocean (Surface Temperature) then fly up to the Lower Troposphere some 8 to 15 Klms above my position the Temperature measurement willtemperature measurement at a ship on the Pacific Ocean (Surface Temperature) then fly up to the Lower Troposphere some 8 to 15 Klms above my position the Temperature measurement willTemperature) then fly up to the Lower Troposphere some 8 to 15 Klms above my position the Temperature measurement willTemperature measurement will be cooler.

Since most of the planet's surface is ocean, an unusually cool ocean surface temperature lowers the overall average.

Ocean surface temperatures increase 0,44 deg C, total global increase 0,55 deg C, land air increase 0,9 deg C, low troposphere (RSS and UAH) 0,44 deg C. I think you would get much of the same impression of the differences with a different timespan.

Exactly I will add low solar — sunspot numbers less then 40 solar flux sub 90 will cause overall sea surface temperatures to decline, due to less UV light which is the light which penetrates the ocean surfaces to the greatest degree thus warms / cools the oceans depending on it's intensity..

As the Earth's surface cools further, cold conditions spread to lower latitudes but polar surface water and the deep ocean can not become much colder, and thus the benthic foraminifera record a temperature change smaller than the global average surface temperature change [43].
