Sentences with phrase «ocean circulation pattern at»

Recall also that the record low area coverage last summer was also due to the wind / ocean circulation pattern at the time.

Not exact matches

At a global scale, the increased melting of the ice sheet contributes to rising sea level and may impact global ocean circulation patterns through the so - called «thermohaline circulation'that sustains among others, the Gulf Stream, which keeps Europe warm.

He believes that no one has thought of combining the two theories before because it's not an intuitive idea to look at how the effects of changing patterns of ocean circulation, which occur on time scales of thousands of years, would effect global silicate weathering, which in turn controls global climate on time scales of 100s of thousands of years.

And what we see is both how complex climate changes can be and how profound an effect changing patterns of ocean circulation can have on global climate states, if looked at on a geological time scale.»

The jet stream off the East Coast of the United States controls an important climate pattern in the Atlantic... «The North Atlantic Oscillation is really driving these changes in ocean circulation,» said Gerald McCarthy, lead study author and an oceanographer at the University of Southampton in the United Kingdom....

Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and regional ocean circulation cycles such as La Nina / El Nino patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.

At least part of the recent US drought is down to patterns of ocean circulation that have decadal to millennial variability.

But certainly models with such a grand name as «General Circulation Model», would include average diurnal atmospheric circulation patterns in tropics, and diurnal and seasonal patterns at latitudes outside the tropics, as well as heat transfer to the deCirculation Model», would include average diurnal atmospheric circulation patterns in tropics, and diurnal and seasonal patterns at latitudes outside the tropics, as well as heat transfer to the decirculation patterns in tropics, and diurnal and seasonal patterns at latitudes outside the tropics, as well as heat transfer to the deeper ocean.

Patterns of ocean and atmosphere circulation shift in response to internal climate dynamics and at a rapid pace determined by the dynamics of the system rather than any external factor.

And so a strong claim can be made that climate change is now at least partially responsible for all global weather although the part played by climate change could be small for any individual climate event relative to other causes such as normal ocean circulation patterns.

The researchers suspect warmer temperatures in the tropical Pacific Ocean amplify warming at high elevations in the Arctic by changing air circulation patterns.

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.)

These ocean upwelling conditions occur beneath a complementary downwelling branch of the atmosphere's Hadley circulation — a planetary - scale flow pattern in both hemispheres that takes humid air ascending at low latitudes, heats and desiccates it in deep precipitating tropical clouds, and then sinks it at midlatitudes, where it is considerably warmer and drier than it was.

The torrent from the glacial lake would have thundered into the North Atlantic, adding a vast freshwater «lid» on the ocean surface that could have rearranged ocean circulation and changed climate patterns, said Donnelly, who is a fellow of both the Ocean and Climate Change Institute and the Coastal Ocean Institute at ocean surface that could have rearranged ocean circulation and changed climate patterns, said Donnelly, who is a fellow of both the Ocean and Climate Change Institute and the Coastal Ocean Institute at ocean circulation and changed climate patterns, said Donnelly, who is a fellow of both the Ocean and Climate Change Institute and the Coastal Ocean Institute at Ocean and Climate Change Institute and the Coastal Ocean Institute at Ocean Institute at WHOI.

A recent study on the North Pacific circulation patterns over the past 1.2 million years determined that sea ice on coastal areas can be an important factor in ocean circulation, therefore influencing climate at global and regional levels.

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.
