In a 150 - year climate simulation, researchers expected that heat radiating off of West African dust would reduce ocean cloud cover.

Not exact matches

But at breaks in the cloud deck, smoke has the opposite effect: It is brighter than the dark ocean surface, reflecting solar radiation and reducing warming.
According to the new findings, Earth may be able to significantly reduce global warming by releasing some of the heat through a «vent» in the cloud cover over the Pacific Ocean.
Ultimately, the group focused its investigation on the five strategies that appear to hold the most promise: reducing emissions, sequestering carbon through biological means on land and in the ocean, storing carbon dioxide in a liquefied form in underground geological formations and wells, increasing Earth's cloud cover and solar reflection.
As a result of atmospheric patterns that both warmed the air and reduced cloud cover as well as increased residual heat in newly exposed ocean waters, such melting helped open the fabled Northwest Passage for the first time [see photo] this summer and presaged tough times for polar bears and other Arctic animals that rely on sea ice to survive, according to the U.S. Geological Survey.
They concluded that the warming ocean had lifted clouds from Monteverde's ridge tops, reducing the moisture available during the toad's breeding season.
This would create a low level barrier of marine clouds that would reduce sunlight warming the surface ocean.
In our own modelling, we have improved the calculations to reduce the amount of numerical diffusion (which helped a lot), and increased resolution (which also helped), but changes to the ocean model also have a big impact, as do Arctic cloud processes and surface albedo parameterisations, so it gets complicated fast.
Particularly «The Sea Surface Temperatures of the East Indian and West Pacific Oceans remain elevated during the La Nina because the stronger trade winds reduce cloud cover.»
The Sea Surface Temperatures of the East Indian and West Pacific Oceans remain elevated during the La Nina because the stronger trade winds reduce cloud cover.
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).
Its warming effect, however, is simultaneously amplified and dampened by positive and negative feedbacks such as increased water vapor (the most powerful greenhouse gas), reduced albedo, which is a measure of Earth's reflectivity, changes in cloud characteristics, and CO2 exchanges with the ocean and terrestrial ecosystems.
The persistent upwelling of cold water in the eastern tropical Pacific would have reduced cloud cover there, via reduced oceanic evaporation, and thus allowed more of the sun's energy to enter the tropical ocean - this would have aided the ocean warming process, as generally the case when the tropical ocean is cooler - than - normal.
The saturated lapse rate will be reduced beneath the clouds and increased above them with little change in ocean surface temperature.
Solar cycles, aerosols, cloud cover and greenhouse gas concentrations each play a roll, and in general, increasing CO2, methane, and N2O in the troposphere will serve to reduce the net flow of energy from oceans to space.
The last cycle was weaker (and so was the minimum in the low altitude cloud cover) which should translate into a reduced warming... and indeed the heat content in the upper oceans decreased, and GW stopped in 2001.
The challenge now is distinguish what portion of rising CO2 reduced clouds and what portion of natural reduction in clouds raised ocean temperatures increasing CO2.»
Could it be that the ocean has maintained surface temperatures at a high level these last seven years because it is dissipating heat it gained while the sun was very active and cloud albedo was reduced in the later C20th?
«Sometimes when that curtain is pulled, as in the case over the North Atlantic ocean in the winter months, this reduces the overall cloud cover» in the lower mid-latitudes, the temperate regions outside of the tropics, Tselioudis said.
A slight change of ocean temperature (after a delay caused by the high specific heat of water, the annual mixing of thermocline waters with deeper waters in storms) ensures that rising CO2 reduces infrared absorbing H2O vapour while slightly increasing cloud cover (thus Earth's albedo), as evidenced by the fact that the NOAA data from 1948 - 2008 shows a fall in global humidity (not the positive feedback rise presumed by NASA's models!)
Environmentalists demand government stop global warming, but oppose remedial actions like spreading iron filings on the oceans to increase uptake of CO2 or spraying chemicals into the atmosphere to create clouds (chemtrails) to block sunlight and reduce global temperatures.
Soon, with the sun beating down on an ocean with reduced clouds, it warms up all across the Eastern Pacific.
The truth may well that the atmospheric greenhouse effect is minimal and quickly reduced by convection, condensation into clouds and rainfall and the real thermostat is the oceans.
Or, agricultural and industrial civilisation alters (silica feeding diatoms, oil smoothing etc etc) the ocean's biochemistry and (aerosol modification) reduces cloud cover and hence albedo.
To me, the prime suspect behind any real warming is changes in cloud cover which may have reduced albedo and may have allowed the oceans to absorb more solar energy.
The Nature study suggests that global warming will mix growing amounts of higher, drier air with ocean clouds over the course of the century, thinning out the clouds and reducing their cooling effect.
I can think of a number of reasons why measured Ocean Heat content may be increasing or seem to be increasing even when albedo due to clouds increases reducing the amount of heat to the surface.
At least not if increased marine low cloud formation reduces DSW flux to the upper ocean layer.
By warming the upper ocean (agrees with observations) and reducing low cloud cover (unclear from observations: ISCCP data are routinely over - interpreted / downright misrepresented on this point).
Another explanation is that the oceans have been warmed by more light from reduced cloud cover — perhaps?
In the northern hemisphere due to the current land / sea distribution the more equatorward the cloud moves the more ocean surface it will cover thus reducing total solar input to the oceans and reducing the rate of accretion to ocean energy content
The probl is the «scientists» get paid to fit emissions into the equation consequently ignore other factors that do provide for AGW such as reduced ITCZ cloud mass ensuring the tropical oceans absorb more SW.
Yes, clouds intercept sunlight which reduces this flux ITO and OTO (out of the ocean, = ITO).
Reduced equatorial cloud cover during La Nina (due to the cooler sea surface temperature), combined with the strong upwelling (Ekman suction) in the eastern equatorial Pacific, does indeed lead to greater warming of the ocean - because it's bringing cool subsurface water to the surface, where it can be heated by the sun.
