Sentences with phrase «water circulation patterns»

Circumpolar deep - water circulation patterns appear to be driving recent WAIS decline (30, 31), but again the record of these patterns is sparse and brief and shows considerable variability, with no clear linkage to greenhouse gas forcing (19, 32 ⇓ — 34).

Data collected by ship and model simulations suggest that increased Pacific Winter Water (PWW), driven by circulation patterns and retreating sea ice in the summer season, is primarily responsible for this OA expansion, according to Di Qi, the paper's lead author and a doctoral student of Liqi Chen, the lead PI in China.

The deepening of the Drake Passage resulted in a change in ocean circulation that resulted in warm waters being directed northwards in circulation patterns like those found in the Gulf Stream that currently warms northwestern Europe.

Oceanographic data and water samples also were collected daily to evaluate seawater chemistry, patterns of water circulation and potential connectivity between Cuban reefs and those in the U.S.

The scientists — whose names are secret — plan to map the ice pack and the ocean floor beneath it, monitor patterns of ocean circulation and analyse water samples for evidence of pollution.

«When water's unusually warm off our coast, it's because the circulation and patterns in the atmosphere has changed, bringing warm water from elsewhere — and this is happening at the same time that we also see high domoic acid in shellfish.

That shift alters where heat from those waters is released into the atmosphere, which in turn knocks circulation patterns out of whack, creating a cascade around the planet.

Are you saying that ocean circulation patterns in the Northern Hemisphere do not reach Antarctic regions where ice is more in the water?

A water based system doesn't achieve much, as the oceans participate in weather and climate, but aren't the primary driving forces, which are global atmospheric circulation patterns and greenhouse gases etc..

A water based system doesn't achieve much, as the oceans participate in weather and climate, but aren't the primary driving forces, which are global atmospheric circulation patterns and greenhouse gases etc..

There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.

«A fundamental new trend in atmospheric and ocean circulation patterns in the Pacific Northwest appears to have begun, scientists say, and apparently is expanding its scope beyond Oregon waters... This year for the first time, the effect of the low - oxygen zone is also being seen in coastal waters off Washington,»

Water temperature, «sea roughness», the changing patterns of oceanic circulation, and the use of carbon by marine creatures - all of these factors play up against one another.

But, the flipside of this is that changes in the thermohaline circulation patterns can alter local water densities, and hence local water volumes, i.e., local sea levels.

Associated with our work on atmospheric circulation patterns we are studying energy transport in the earth system and the transport of water in the atmosphere on different time and space scales.

It is an oscillation which reflects the predominant ocean circulation patterns and the temperature of the water itself.

Ongoing changes in ocean circulation patterns, which are helping to drive warm water from other parts of the sea closer to the Antarctic continent, are also believed to be a major factor.

Observations suggest that variability in oceanographic conditions in the Arctic is very largely driven by the consequences of the flows through open passages to both Atlantic and Pacific Oceans, which themselves respond to the different and characteristic variability of the circulation patterns of each ocean: each inflow is not only variable in volume of water transported but also in the temperature of the water imported.

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.)

Periodic events called El Niño and La Niña alter the circulation of warmer and cooler water in ocean currents, leading to changes in climatic patterns across large regions.

The problems we are working on range from basic studies of circulation patterns of water in the ocean and groundwater flow systems to the variability of the oceanic circulation under natural and anthropogenically forced conditions or the transport and transformation of contaminants.

Falling back on the surface temperatures as the metric for the most societal relevant climate metric, even if its period of record is longer, is not a reason to focus on it, if it does not serve the purpose of telling us if humans are significantly altering these circulation patterns, and thus the weather and ocean conditions that matter the most in terms of the impacts on water resources, food, energy, human health and ecosystem function.

They demonstrate changing patterns in global circulation, the closest visual aid to show how weather becomes climate imnhso: increased water vapor, increased energy, and changes in the way the jet stream is acting (I'm repeating myself).

Therefore, they sought an answer in terms of the atmospheric flow pattern that drives ocean circulation and results in the advection of warm water into the northeastern North Atlantic.

It's not new information that the melted ice will change sea levels, ocean circulation patterns and water supplies, as well as release additional greenhouse gasses thanks to melted permafrost.

This in turn helps explain how factors such as fresh water from melting ice or changes in global wind patterns might lead to large - scale changes in ocean circulation or climate in the future.

The models (and there are many) have numerous common behaviours — they all cool following a big volcanic eruption, like that at Mount Pinatubo in 1991; they all warm as levels of greenhouse gases are increased; they show the same relationships connecting water vapour and temperature that we see in observations; and they can quantify how the giant lakes left over from the Ice Age may have caused a rapid cooling across the North Atlantic as they drained and changed ocean circulation patterns.

Researchers also knew that global circulation patterns in the oceans — patterns caused mostly by variations in water temperature and saltiness — affect global climate.

Changes in the speed of the Atlantic circulation pattern — known as Atlantic Meridional Overturning Circulation — that influences the world's oceans because it acts like a conveyor belt moving water around circulation pattern — known as Atlantic Meridional Overturning Circulation — that influences the world's oceans because it acts like a conveyor belt moving water around Circulation — that influences the world's oceans because it acts like a conveyor belt moving water around the planet.
