Sentences with phrase «circulation system over»
A new analysis using changes in cloud cover over the tropical Indo - Pacific Ocean showed that a weakening of a major atmospheric circulation system over the last century is due, in part, to increased greenhouse gas emissions.

The simulations suggest that over decades, these warming events dramatically perturb the ocean surface, affecting the flow of the Atlantic Meridional Overturning Circulation, a system of currents that acts like a conveyor belt moving water around the planet.
Why It Matters: As the grandest feature of atmospheric circulation over much of North America, the jet stream plays a key role in orchestrating weather systems that usher in the seasons.
The weather pattern over northern India, the Himalayas, and Pakistan is usually dominated by a circulation pattern that prevents mid-latitude weather systems from penetrating very far south.
Issues with circulation and immune system function may be long - standing over many years.
Red yeast rice has been revered for its health - enhancing properties for over two thousand years — records dating back to the Ming Dynasty (1368 - 1644) describe red yeast's role in promoting a healthy cardiovascular system by improving blood circulation and reducing clotting.
Over the years, this creates fibrosis in the tissues and it impairs circulation and the transport system of the body.
Natural heart tonics such as Heart and Circulation Tonic and cardiovascular supportive supplements can surely help to improve the strength of the cardiac muscles and over all circulatory system health.
A tropical cyclone is the generic term for a non-frontal synoptic scale low - pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).
Haarsma et al. (2015) argue on the basis of model simulation that the weakening of the Gulf Stream system will in the future be the main cause of changes in the atmospheric summer circulation over Europe.
Second, energy in vs. energy out of the system can hardly balance until we have a better handle on the circulation of the ocean (over 95 % of the heat capacity of Earth) and its rate of heat uptake.
There is also a natural variability of the climate system (about a zero reference point) that produces El Nino and La Nina effects arising from changes in ocean circulation patterns that can make the global temperature increase or decrease, over and above the global warming due to CO2.
Due to the relatively cool waters around the Azores the classical «Azores high» had a good chance to develop and settle, together with low pressure systems around Iceland leading to a strong west circulation (a positive NAO) over Europe.
They produced a static condition when the major natural mechanism causing ozone variation over Antarctica is an intense atmospheric circulation system associated with the Circumpolar Vortex.
According to their modeling studies, the difference in the amount of incoming solar radiation, in this case, primarily in the ultraviolet (UV) wavelengths, during the minima and maxima of the 11 - yr solar cycle are large enough to produce a characteristic change in the winter circulation pattern of the atmosphere over North America... When the NAO is in its negative phase, more cold air can seep south from the Arctic and impact the lower latitudes of Europe and the eastern U.S., which helps spin up winter storm systems.
In recent decades, much research on these topics has raised the questions of «tipping points» and «system flips,» where feedbacks in the system compound to rapidly cause massive reorganization of global climate over very short periods of time — a truncation or reorganization of the thermohaline circulation or of food web structures, for instance, caused by the loss of sea ice or warming ocean temperatures.
As the Sun cools with amplification through the systems — as El Nino gives way to La Nina dominance — as Atlantic meridional overturning circulation declines over the century.
Tropical cyclones are low pressure systems that form over warm tropical waters and have well defined wind circulations of at least gale force strength (sustained winds of 63 km / h or greater with gusts in excess of 90 km / h).
«The Walker circulation is caused by the pressure gradient force that results from a high pressure system over the eastern Pacific ocean, and a low pressure system over Indonesia.
Over time some of those local systems join to feed each other or inhibit each other and then you have large scale circulations.
However, over the South Pole, the vortex circulation system is larger, stronger and more predictable from year to year, Salawitch said.
On top of this, large questions remain over how cirrus cloud thinning could affect other aspects of the climate system, such as atmospheric circulation, the paper concludes:
It is a signal that propagates over decades through the components — ice, ocean and atmospheric circulation and biology — of the climate system.
The evidence in favour of such a link is the observation that the ITCZ and other air circulation system components have changed over those longer time spans.
«Relatively cool waters in the eastern Pacific often result in stubborn summer high - pressure systems over the eastern states that block storms, reducing the frequency of precipitation below normal,» noted study co-author Richard Healy of the Woods Hole Oceanographic Institution, Woods Hole, Mass. «Less frequent storms result in higher surface and atmospheric temperatures that then feedback on the atmospheric circulation to further reduce storm frequency and raise surface temperatures even more.»
The weather pattern over northern India, the Himalayas, and Pakistan is usually dominated by a circulation pattern that prevents mid-latitude weather systems from penetrating very far south.
