Sentences with phrase «by ocean circulation patterns»

Even if it is assumed that 100 % of the recent global sea level rise is caused by anthropogenic sea level rise (an assumption that will be examined in Part II), local sea level rise can be dominated by ocean circulation patterns, land use practices and astronomical tides.

Not exact matches

The Tibetan Plateau in China experiences the strongest monsoon system on Earth, with powerful winds — and accompanying intense rains in the summer months — caused by a complex system of global air circulation patterns and differences in surface temperatures between land and oceans.

They range from changes in ocean circulation patterns caused by glacial meltwater entering the ocean to the cosmic - impact theory.

The first collection of papers establishes that (a) decadal and multi-decadal ocean circulation patterns (AMO, PDO, NAO, ENSO) have significantly modulated precipitation and temperature changes in recent decades, and the second collection of papers confirm that (b) natural ocean oscillations are, in turn, modulated by solar activity.

There is evidence that ocean circulation patterns are disrupted by glaciations.

Hank states,» That's a known reversing pattern — positive ACRI phase characterized by cyclonic ocean circulation and a warmer and wetter climate.»

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.

Francis, who wasn't involved with either study, is one of the main proponents of an idea that by altering how much heat the ocean lets out, sea ice melt and Arctic warming can also change atmospheric circulation patterns, in particular by making the jet stream form larger peaks, or highs, and troughs, or lows.

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.

By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.

But matters are greatly complicated by atmospheric circulation patterns, cyclic changes in temperatures over the oceans, and the shapes of land masses.

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.

The Quaternary glacial history of the Arctic Ocean is characterized by the repeated build - up and decay of circum - Arctic ice sheets on the continental shelves, the development and disintegration of ice shelves, and related changes in ocean - circulation patterns and sea ice cover50, 51,52,53,5Ocean is characterized by the repeated build - up and decay of circum - Arctic ice sheets on the continental shelves, the development and disintegration of ice shelves, and related changes in ocean - circulation patterns and sea ice cover50, 51,52,53,5ocean - circulation patterns and sea ice cover50, 51,52,53,54,55.

The climate models have gotten more complex, for sure, with thousands of estimated parameters for warming potential, vorticity, circulation patterns, absorption of heat, pressure, energy, and momentum by various layers or atmosphere, land, ocean, and sea - ice.

That would change the air circulation patterns resulting in the observed wind effect on the ocean surfaces but would itself have been caused by changes in the rate of release or absorption of energy from the ocean surfaces.

They are being pushed out of the Arctic Ocean by a circulation pattern that starts over near Siberia; occasionally you'll see a Siberian tree washed ashore along this coast of Greenland.

The large interannual to decadal hydroclimatic variability in winter precipitation is highly influenced by sea surface temperature (SST) anomalies in the tropical Pacific Ocean and associated changes in large - scale atmospheric circulation patterns [16].

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.

A change in ocean heat content can also alter patterns of ocean circulation, which can have far - reaching effects on global climate conditions, including changes to the outcome and pattern of meteorological events such as tropical storms, and also temperatures in the northern Atlantic region, which are strongly influenced by currents that may be substantially reduced with CO2 increase in the atmosphere.

Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4

b) atmospheric and ocean circulation patterns since 1950 predominantly caused by natural processes.

Gyre - Basin - scale ocean horizontal circulation pattern with slow flow circulating around the ocean basin, closed by a strong and narrow (100 - 200 km wide) boundary current on the western side.

The temperature is determined by the state of the system — and the energy dynamic is primarily determined by patterns of ocean and atmospheric circulation.

Many of these circulation patterns are thought to be driven by geographical features, such as the strong heating near the tropics nd over parts of the ocean basin, such as the Walker cell (see here).

This seems to be caused primarily by a change in the circulation patterns in the Pacific Ocean, although solar cooling is also contributing to an extent that is uncertain.

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

A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable «Achilles heel» in the North Atlantic and changing mile - deep ocean circulation patterns, which in turn affect Earth's climate.

It is particularly motivated by the uncertainties in projections of ocean heat uptake, global - mean sea - level rise due to thermal expansion and the geographical patterns of sea - level change due to ocean density and circulation change.
