Sentences with phrase «changes in atmospheric circulation associated»

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.

Not exact matches

Tropical widening is associated with several significant changes in our climate, including shifts in large - scale atmospheric circulation, like storm tracks, and major climate zones.

The top priorities should be reducing uncertainties in climate sensitivity, getting a better understanding of the effect of climate change on atmospheric circulation (critical for understanding of regional climate change, changes in extremes) and reducing uncertainties in radiative forcing — particularly those associated with aerosols.

The well - known impact of El Niño on reducing Atlantic hurricane activity is in fact due to increased shear from the associated atmospheric circulation changes.

A large decrease in atmospheric CH4 concentrations (several tens of parts per billion; Spahni et al., 2003) reveals the widespread signature of the abrupt «8.2 ka event» associated with large - scale atmospheric circulation change recorded from the Arctic to the tropics with associated dry episodes (Hughen et al., 1996; Stager and Mayewski, 1997; Haug et al., 2001; Fleitmann et al., 2003; Rohling and Palike, 2005).

When many causes all interact — and abrupt climate change candidates include the thermohaline circulation, the atmospheric circulation associated with the North Atlantic Oscillation, changes in tropical evaporation, and changes in albedo — the human mind needs some help.

Changes in sea - surface temperatures (SSTs) also have an effect by bringing about associated changes in atmospheric circulation and precipiChanges in sea - surface temperatures (SSTs) also have an effect by bringing about associated changes in atmospheric circulation and precipichanges in atmospheric circulation and precipitation.

The most interesting feature is the step change in cloud — associated with a change in ocean and atmospheric circulation — in the 1998/2001 climate shift.

Here we use an ensemble of simulations with a coupled ocean — atmosphere model to show that the sea surface temperature anomalies associated with central Pacific El Niño force changes in the extra-tropical atmospheric circulation.

Clouds change — associated with changes in ocean and atmospheric circulation — in the short term and radically change the energy budget.

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].

Shows that the changes in discharge extremes are related to the regional pluriannual rainfall variability and the associated atmospheric circulation as well as to tropical large - scale climatic indicators

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Cycles.

Independent evidence from multiple sources suggest — if «real» — that recent warming was all cloud changes associated with decadal changes in ocean and atmospheric circulation.

Nor in a Southern Hemisphere context are «atmospheric circulation changes» independent of temperature changes: changes in temperature are invariably associated with atmospheric circulation changes, particularly with movements of the southern westerlies towards and away from the equator.

There is growing observational data, physical analysis of possible mechanisms, and model agreement that human - caused climate change is strengthening atmospheric circulation patterns in a way «which implies that the periodic and inevitable droughts California will experience will exhibit more severity...» «there is a traceable anthropogenic warming footprint in the enormous intensity of the anomalous ridge during winter 2013 — 2014 and the associated drought.»

There are large changes with the El Nino - Southern Oscillation and volcanoes as well step changes and decadal variability to do with changes in cloud associated with changes in ocean and atmospheric circulation.

To the helpful set of references you've provided dealing with this broader set of questions, I would in a shamelessly self - promoting manner also offer this publication that deals with the issue of how atmospheric circulation changes associated with anthropogenic climate change might alter growing season length in the Northern Hemisphere:

I think it is really important to make that distinction - that there are a number of factors that influence the extent of Arctic sea ice, some of them of course associated with changes in the radiative forcing from the atmosphere, as a result of anthropogenic greenhouse gases and aerosols, but also changes in the atmospheric circulation and also the advection of heat into or out of the Arctic by the ocean circulation.

The focus on Europe, aided by the increase in resolution, has revealed previously undiscussed impacts, particularly those associated with changing atmospheric circulation patterns.

Winter precipitation is also affected by the changing atmospheric circulation, with localised increases in precipitation associated with more winter storms and a strengthened winter storm track.

We see similar excursions from the trend line in our modelling, so we feel that there is an actual variability here that is associated with year - to - year changes in the atmospheric circulation.
