Not exact matches

«When the weather fluctuates between warm and cold and in bodies of water where there are currents underneath the ice, it can weaken the surface of the ice and make it dangerously fragile even though it seems to be frozen solid,» said Joe Pecoraro, manager of the Park District's Beaches and Pools Unit, who narrated the demonstration.

Scientists first thought this water was melting from surface ice, but that interpretation is less likely for the slopes near the equator, where the surface is probably too warm for ice.

And around Antarctica, where even the surface ocean water is already quite cold and dense, some of that water in the ocean depths, which is also carbon rich, eventually warmed enough so that it became less dense than the water above it.

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.

Using the Large Binocular Telescope Interferometer, or LBTI, in Arizona, the HOSTS Survey determines the brightness and density of warm dust floating in nearby stars» habitable zones, where liquid water could exist on the surface of a planet.

Although today's Martian surface is barren, frozen and uninhabitable, a trail of evidence points to a once warmer, wetter planet, where water flowed freely.

It's unclear whether this year's strong El Niño event, which is a naturally occurring phenomenon that typically occurs every two to seven years where the surface water of the eastern equatorial Pacific Ocean warms, has had any impact on the Arctic sea ice minimum extent.

Researchers identify such planets by first looking for those that are situated within the «habitable zone» around their parent stars, which is where temperatures are warm enough for water to pool on the surface.

This shift strengthens the ocean currents that bring warm, salty water to the surface, where it accelerates the melting of Antarctic ice.

The warming of the oceans by sunlight, makes the daytime surface waters more bouyant than the cooler waters below and this leads to stratification - a situation where the warmer water floats atop cooler waters underneath, and is less inclined to mix.

It is harvested from the surface of the water where it forms when winds are calm and the weather is warm.

Snorkeling is possible in almost any body of water, but snorkelers are most likely to be found in locations where there are minimal waves, warm water, and something particularly interesting to see near the surface — exactly like the Cayman Islands!

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

A further point where I need clarification is that, in Part I, you seemed to be suggesting that the West Pacific warm pool develops due to the trade winds blowing surface water in that direction.

These are large rotating masses of water, in each ocean basin, where ocean currents converge at their centre and are forced downwards, taking warm surface water with them.

Now scientists have measured a rapid recent expansion of desert - like barrenness in the subtropical oceans --- in places where surface waters have also been steadily warming.

The surface waters of the tropical Atlantic are then transported, via the Gulf Stream, towards the high latitudes where they warm the atmosphere before plunging into the abysses in the convection zones situated in the seas of Norway, Greenland and Labrador.

Even in cases where it is cold or where SSTs [sea surface temperatures] are cold, or where water vapor is low, they are still warmer / moister than they would have been without the global warming.

Although water vapour is a greenhouse gas it had no warming effect at the surface where the vapour simply acquired the same temperature as the surrounding air molecules.

4) By interpreting the analyss of Bob Tisdale, the global sea surface temperatures used by Endersbee in his calculations have been controlled by warming of the sea surface waters outside the tropical sea surface i.e. mainly by the warming of the sea surface waters of higher latitudes where the sea surface CO2 sinks are.

The warmer the ocean becomes, the less water rises from deeper down, meaning fewer resources will be brought to the surface water where phytoplankton live.

Most of the deep ocean warming is occurring in the subtropical ocean gyres - vast rotating masses of water in each ocean basin where near - surface currents converge and are forced downward into the ocean interior.

Since the whole world does not appear to freeze during a ice age, the must be massive ice making going at the pole driven by heat lifting oceans of water to the sky from the equator where it is pushed by the expanding air and vapor to the poles areas where it returns to the surface and follows cold land like a culvert between warmer expanding ocean air back down to the equatoral region.

The satellite image showed that sea surface heights were about 4 inches (10 cm) above normal in warmer regions (these appear red in the image), while the regions where cooler water prevails are 6 to 7 inches (14 to 18 cm) below normal (these appear purple).

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.

This has never been demonstrated, there is no evidence at all that it exists, and all the available evidence says the basic heating effect of CO2 is 1.1 C per doubling is all there is and that much warming only happens in very dry environments with increasingly less surface warming where water is available to evaporate.

Just to let you know how stupid the global warming activists are, I've been to the south pole 3 times and even there, where the water vapor is under 0.2 mm precipitable, it's still the H2O that is the main concern in our field and nobody even talks about CO2 because CO2 doesn't absorb or radiate in the portion of the spectrum corresponding with earth's surface temps of 220 to 320 K. Not at all.

So where there is water to evaporate the surface doesn't get warmer but instead the cloud deck rises about 100 meters per doubling and where there was once dry cool air above the clouds there's now a warm cloud occupying that layer in the atmosphere instead.

As mentioned above, highest surface densities in the world ocean are reached where water is very cold, while lower densities are found in the saltier but warmer tropical and subtropical areas.

During the El Nino, the discharge phase, warm water that had been stored in the Pacific Warm Pool sloshes to the east where it spreads across the surface, raising sea surface temperatures in the tropical Paciwarm water that had been stored in the Pacific Warm Pool sloshes to the east where it spreads across the surface, raising sea surface temperatures in the tropical PaciWarm Pool sloshes to the east where it spreads across the surface, raising sea surface temperatures in the tropical Pacific.

As part of the planet's reciprocal relationship between ocean circulation and climate, this conveyor belt transports warm surface water to high latitudes where the water warms the air, then cools, sinks, and returns towards the equator as a deep flow.»

An El Nino is a change in the movement of water that has been warmed with contact with the surface, so that warm water that has been building up at depth over time changes its movement pattern and moves closer to the surface (and to a different horizontal location) where heat is released.

When surface winds are strong, they stir the Southern Ocean and lift the warm water (red) onto the continental shelf where the additional heat contributes to melt of the ice shelf.

If the earth core is somewhere in the 5,000 to 10,000 deg C range; and the surface / lower troposphere is 15 deg C; and you say that the deep oceans are at 4 deg C; and are sucking in «heat» from the warm surface waters; where the hell is all that heat piling up down there.

In the Atlantic Ocean, the current known as the Atlantic Meridional Overturning Circulation (AMOC) ferries warm surface waters northward — where the heat is released into the atmosphere — and carries cold water south in the deeper ocean layers, according to the National Oceanic and Atmospheric Administration.

Warm water on Mars, boils - it's lacks atmospheric pressure lowers the boiling point to somewhere around 5 to 10 C. And 5 C water would not boil on Mars, but it would evaporate quicker on Mars then it does on Earth - because no where on Earth is drier than Mars [due to changing temperatures, frost does form on the Mars surface at equator and at nite - this requires the thin Mars air to become saturated - but generally very dry.

Warming bottom waters in deeper parts of the ocean, where surface sediment is much colder than freezing and the hydrate stability zone is relatively thick, would not thaw hydrates near the sediment surface, but downward heat diffusion into the sediment column would thin the stability zone from below, causing basal hydrates to decompose, releasing gaseous methane.

It means that the global sea surface temperatures used by Endersbee in his calculations have been controlled by warming of the sea surface waters outside the tropical sea surface i.e. mainly the warming of the sea surface waters of higher latitudes where the sea surface CO2 sinks are.

Apologies if this has already been stated, but my view on decreased Arctic ice cover is: - 1, as Judith pointed out, when ice is at a minimum the sun is already so low in the sky that there is no noticeable change to albedo, 2 when there is ice cover warm water is kept at depth by differences in salinity, When there is open water, storms mix the haline layers bringing warm water to the surface where it can more readily radiate it's energy into outer space.

On the contrary, whatever warm, hypersaline water sinks below the surface because of its great density is mixed relatively quickly by winds into the upper layer of the ocean, where it transfers its heat to colder parcels by conduction.

Furthermore, in the absence of such warming, ocean mixing would normally be expected to be constantly refreshing the water at the ocean's surface, the place where it meets with air and dissolves CO2.

De Witt, are you saying «THS???» because you don't know it stands for tropical hot spot [which I can't believe] or because you don't get the connection between backradiation and a THS, which I understood to be the case because the Troposphere would warm faster than the surface since it is being heated by a warmer surface, to wit, the surface of the planet which is getting warmed by the aforesaid backradiation; and in addition to but not withstanding that the troposphere whould also rise which would be another aspect of the THS, with the final characteristic being that said THS would occur in the tropics where the warming effect of extra water would be most pronounced, also as a consequence of backradiation?

It's unclear whether this year's strong El Niño event, which is a naturally occurring phenomenon that typically occurs every two to seven years where the surface water of the eastern equatorial Pacific Ocean warms, has had any impact on the Arctic sea ice minimum extent.

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.
