Not exact matches

Lyon thinks this change in temperatures has altered atmospheric circulation patterns, cutting off the supply of moisture to east Africa (Geophysical Research Letters, DOI: 10.1029 / 2011GL050337).

To get around those problems in relating tornadoes to climate, the Columbia team shifted its focus from the tornadoes themselves to the atmospheric factors that are crucial for tornado formation, factors that are themselves altered by the ENSO pattern.

The abstract of the Ainsworth et al seems to provide some support for both TC and BPL: «Rising atmospheric [CO2] is altering global temperature and precipitation patterns, which challenges agricultural productivity,» yet «rising [CO2] provides a unique opportunity to increase the productivity of C3 crops...»

«We think the recent snowy winters could be caused by the retreating Arctic ice altering atmospheric circulation patterns by weakening westerly winds, increasing the amplitude of the jet stream and increasing the amount of moisture in the atmosphere,»

One is that climate change is altering the pattern of atmospheric circulation, causing more ozone to be carried away from the tropics.

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.

Three of these five intervals coincided with multidecadal hemispheric climate - regime shifts, which were characterized by a switch between distinct atmospheric and oceanic circulation patterns, a reversal of NHT trend, and by altered character of ENSO variability.

Forests can affect the global climate system by altering large - scale patterns in atmospheric waves and jet streams, a mechanism termed «teleconnection patterns» (e.g., [12, 15 — 19]-RRB-.

But in a given model you can often find ways of altering the model's climate sensitivity through the sub-grid convection and cloud schemes that affect cloud feedback, but you have to tread carefully because the cloud simulation exerts a powerful control on the atmospheric circulation, top - of - atmosphere (TOA) and surface radiative flux patterns, the tropical precipitation distribution, etc..

Greenhouse gases have a cooling effect on the stratosphere, and climate change is likely to also alter atmospheric transport and circulation patterns.

It also backs up other research: that human artefacts are now embedded in geological strata, while human action is beginning to alter the biological cycles and atmospheric patterns in dangerous ways and has certainly begun to alter the climate cycle.

These anomalies are then transported by major ocean currents to locations where the stored energy is released into the atmosphere, altering atmospheric pressure and moisture patterns that can ultimately affect regional precipitation.

In addition, human - induced climate change may alter atmospheric circulation, dislocating historical patterns of natural variability and storminess.

Such a change could alter both ocean and atmospheric circulation patterns around the world.

Variations in ocean circulation speeds account for significant instances of climate change, changing the hydrological cycle and altering atmospheric circulation patterns as well.

Such oscillations might also alter hurricane patterns, but the main driver of hurricanes is warm sea surface temperatures > 27C (we can all agree on that, I hope); atmospheric conditions also need to be conducive (see the above comment on this year's rip - snorting season).

The changed atmospheric heating alters the jet streams and storm tracks and influences weather patterns for the duration of the event (Trenberth et al. 1998).
