Sentences with phrase «rapid changes in circulation»

As a result, the phenomena I describe above, with the rapid changes in circulation regimes, are not represented in the climate models at all except as gridcell sized averages...

Not exact matches

We know, however, that rapid warming of the planet increases the risk of crossing climatic points of no return, possibly setting in motion large - scale ocean circulation changes, the loss of major ice sheets, and species extinctions.
Zhang, X., Sorteberg, A., Zhang, J., Gerdes, R. & Comiso, J. C. Recent radical shifts of the atmospheric circulations and rapid changes in the Arctic climate system.

There has been an ongoing debate, both in and outside the scientific community, whether rapid climate change in the Arctic might affect circulation patterns in the mid-latitudes, and thereby possibly the frequency or intensity of extreme weather events.
Recent evidence from ice - core drilling in Greenland indicates that similar fluctuations also occurred during the previous interglacial period, possibly due to rapid changes in ocean circulation.
Examples of such nonlinear behaviour include rapid circulation changes in the North Atlantic and feedbacks associated with terrestrial ecosystem changes.
«The authors write that «the notorious tropical bias problem in climate simulations of global coupled general circulation models manifests itself particularly strongly in the tropical Atlantic,»... they state that «the climate bias problem is still so severe that one of the most basic features of the equatorial Atlantic Ocean — the eastward shoaling thermocline — can not be reproduced by most of the IPCC assessment report models,... as they describe it, «show that the bias in the eastern equatorial Atlantic has a major effect on sea - surface temperature (SST) response to a rapid change in the Atlantic Meridional Overturning Circulation (AMcirculation models manifests itself particularly strongly in the tropical Atlantic,»... they state that «the climate bias problem is still so severe that one of the most basic features of the equatorial Atlantic Ocean — the eastward shoaling thermocline — can not be reproduced by most of the IPCC assessment report models,... as they describe it, «show that the bias in the eastern equatorial Atlantic has a major effect on sea - surface temperature (SST) response to a rapid change in the Atlantic Meridional Overturning Circulation (AMCirculation (AMOC).»
The expected response to a step increase in CO2 is to move from the relatively stable Holocene climate through a period of rapid (in geological terms) change to a new, relatively stable climate with a higher overall temperature and somewhat different circulation and rainfall patterns.
Changes in ocean circulation are thought to be able to produce large rapid temperature cChanges in ocean circulation are thought to be able to produce large rapid temperature changeschanges.
Motivated by findings that major components of so - called cloud «feedbacks» are best understood as rapid responses to CO2 forcing (Gregory and Webb in J Clim 21:58 — 71, 2008), the top of atmosphere (TOA) radiative effects from forcing, and the subsequent responses to global surface temperature changes from all «atmospheric feedbacks» (water vapour, lapse rate, surface albedo, «surface temperature» and cloud) are examined in detail in a General Circulation Model.
Driven by changes in ocean circulation, the rapid sea level rise will bring increased risk of damage from hurricanes and winter storm surges, researchers say.
Abrupt climate changes, such as the collapse of the West Antarctic Ice Sheet, the rapid loss of the Greenland Ice Sheet or large - scale changes of ocean circulation systems, are not considered likely to occur in the 21st century, based on currently available model results.
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.
