The deflection of these waves back into the troposphere alters circulation to build a high-pressure ridge at 40°N that intensifies winds at the surface and redirects storms into Canada and northern Eurasia.
Some scientists have suggested that this so-called Arctic amplification can alter circulation patterns that affect weather in the United States, Europe, and Asia, potentially helping cause the powerful winter storms and deep freezes that have blasted the midlatitudes over the past decade.
Thus, altered circulation in the morphants was not the consequence of a compromised vascular system.
Francis has hypothesized that the warming Arctic is altering global circulation patterns, which could make the warm west cold east pattern more common.
Changing trade winds here may have helped lower sea surface temperatures by altering ocean circulation patterns and making it so heat that otherwise would be warming the air is now trapped deep underwater.
Brinker et al. have focussed attention on possible factors other than altered glymphatic circulation that may have altered the width of interstitial spaces in animals exposed to the very artificial recording conditions, including changes in arterial blood pressure, venous blood pressure, stress hormone levels, and blood gases [ 17].
Back-and-forth oscillations in the Pacific temperatures alter atmospheric circulation patterns that deliver moisture to North America.
More open water also means that more heat from the sun is absorbed by the dark, ice-free surface of the Arctic Ocean, triggering an accelerating cycle of warming that can alter ocean circulation and, in turn, the entire global climate.
There is not enough evidence for scientists to know for sure whether the influx of fresh water in the North Atlantic has come from an already altered ocean circulation, changes in rainfall patterns or rivers, or glacial and Arctic Ocean ice.
In the case of the Sichuan storms, soot had altered air circulation patterns and redistributed rainfall.
