Sentences with phrase «involves changes in circulation»

Although the rising average global surface temperature is an indicator of the degree of disruption that we have imposed on the global climate system, what's actually happening involves changes in circulation patterns, changes in precipitation patterns, and changes in extremes.

Not exact matches

The foundation of the research involved tracking the changes in ocean circulation in new detail by studying three sediment cores extracted from the seafloor of the Gulf of Mexico in 2010 during a scientific cruise.

Hoerling and Kumar (2003) attributed the drought to changes in atmospheric circulation associated with warming of the western tropical Pacific and Indian oceans, while McCabe et al. (2004) have produced evidence suggesting that the confluence of both Pacific decadal and Atlantic multi-decadal fluctuations is involved.

The state of attention is characterized by changes in the physical and physiological state of the body, for example, increased blood circulation in actively involved organs.

So was there a climate shift after the turn of the century involving changes in ocean and atmospheric circulation involving cloud changes?

This explanation involves a displacement of an oceanic front and hence a change in the circulation structure.

Various mechanisms, involving changes in ocean circulation, changes in atmospheric concentrations of greenhouse gases or haze particles, and changes in snow and ice cover, have been invoked to explain these sudden regional and global transitions.

I will now analyse how the system could work and show that composition changes not involving changes in mass only affect atmospheric volume and circulation patterns and not surface temperature.

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.

Together, these results suggest that there are decadal - scale changes in the atmosphere involving circulation, water vapor, clouds and radiation that may play a role in PDV, and are worthy of further study.»

The abrupt shifts in Pacific Ocean circulation involve changes in the PDO in the north - eastern Pacific and coincident changes in the frequency and intensity of ENSO events.

Dr Peter Stott, who leads the Climate Monitoring and Attribution team at the Met Office and wasn't involved in the paper, says we shouldn't admit defeat and ignore the impacts of climate change on circulation patterns.

The Arctic climate affects the world: Changes in sea ice affect ocean circulation, which, in turn, affects atmospheric circulation that then impacts the globe, said Bruce Forbes, a geographer at the Arctic Center at the University of Lapland in Finland, who was not involved in the study.

The results obtained provide evidence that the mechanism of solar activity and cosmic ray influences on the lower atmosphere circulation involves changes in the evolution of the stratospheric polar vortex.

It is not clear that the world is warming post the 1998/2001 climate shift — that involved a climatically significant step change in albedo as a response to abrupt changes in ocean and atmospheric circulation.

The mechanism involves cloud changes in these major internally driven reorganizations atmospheric and ocean circulation.

The most natural type of long term variability is in my view based on slowly varying changes in ocean circulation, which doesn't necessarily involve major transfer of heat from one place to another but influences cloudiness and other large scale weather patterns and through that the net energy flux of the Earth system.

How atmospheric and ocean circulation responds to various changes in forcing would need to be detailed if someone wanted to «prove» anthropogenic forcing is involved other than a minor increase in the average surface temperature.

They involve changes in ocean and atmospheric circulation, ice, cloud, dust and biology.

In addition to the main threshold for a complete breakdown of the circulation, other thresholds may exist that involve more - limited changes, such as a cessation or diminishment of Labrador Sea deep water formation (Wood et al., 1999).

These results also increase our overall understanding of glacial − interglacial cycles by putting further constraints on the timing and strength of other processes involved in these cycles, like changes in sea ice and ice sheet extents or changes in ocean circulation and deep water formation.

Unlike Charney climate sensitivity, which is related to the strength of feedbacks involving short timescale climate processes such as those involving clouds and water vapor, Earth System sensitivity also integrates feedbacks involving long timescale changes in the cryosphere, terrestrial vegetation, and deep ocean circulation.

Though more work is needed to fully understand these long term trends, especially what happens from the mid-1970's, it is likely that changes in ocean circulation involving some combination of the Atlantic meridional overtuning circulation and the subtropical cells are required to explain the observations.

The circulation changes alter all the processes involved in the rate of energy transfer from surface to space.

back to the horizontal gradient, if the upper tropospheric thermal wind shear increase is greater than the decrease of the lower layer, then maybe the overall baroclinic instability would be stronger — but currently the upper level eddy circulations do not transport much heat poleward, so would the structure of cyclones change so that a deeper layer of air is involved in the thermal advection, compensating for a weaker temperature gradient?
