Sentences with phrase «different circulation patterns»

So the question to me is: are there reasons for concern that Earth's large - scale atmospheric circulation could be disrupted by climate change into an entirely new regime, with completely different circulation patterns?

Vector wind analyses were computed to explain the composite seasonal precipitation anomaly results in terms of different circulation patterns associated with these two wet groups.

This is not the case with extratropical volcanoes, such as the Chilean one, due to different circulation patterns in the stratosphere at those latitudes.

The flow of energy between different circulation patterns is dependent on fram of reference (Eulerian vs transformed Eulerian); The Ferrel Cell is the result of some average upward motion poleward of some average downward motion with return flows at lower and higher altitudes, superimposed on the average temperature distribution.

This variability includes the Pacific Decadal Oscillation (PDO), a long - lived El Niño - like pattern of Pacific climate variability that works like a switch every 30 years or so between two different circulation patterns in the North Pacific Ocean.

Not exact matches

Scientists believe that the different pattern of deep ocean circulation was responsible for the elevated temperatures 3 million years ago when the carbon dioxide level in the atmosphere was arguably what it is now and the temperature was 4 degree Fahrenheit higher.

Vuillard's interest in patterned surfaces and domestic intimacy led him to produce many of his most compelling works around 1900 in two radically different formats: on the one hand, large - scale paintings, conceived as decorative ensembles and commissioned for private, domestic spaces; and, on the other, intimate color lithographs, produced in series and destined for broader circulation.

The installations that Vancouver artists Michelle Allard and Khan Lee create in Circulation Patterns occupy the three - dimensional space of the SFU Gallery in very different ways.

However, if the loss of Arctic Sea ice has significantly changed global atmospheric circulation patterns, then we are dealing with a different system that has only been in existence since 2007, and we do not know how often to expect crop failures.

The reason is that the Holocene has a different pattern of ocean circulation with vigorous convection in the Greenland - Norwegian Seas.

The effects of circulation change in the North Atlantic are different to (potentially solar - driven) rainfall variability in the sub-tropics and are different again from the impacts of changing frequency and intensity in El Nino patterns.

The real world atmosphere is a large body of air, has circulation patterns, and is not held in a container, so the effects of CO2 have different effects and behaviours than a simple container and very low concentrations can have significant effects.

Diminishing Arctic sea ice can cause changes in atmospheric circulation that lead to a circulation pattern that is different than the «negative phase» of the Arctic Oscillation.

Associated with our work on atmospheric circulation patterns we are studying energy transport in the earth system and the transport of water in the atmosphere on different time and space scales.

Our research is focused on understanding the circulation patterns in the atmosphere on different time scales and how they are driven through different processes.

Switching between different phases of ocean / atmospheric circulation patterns is not the only thing that has happened between 1909 and today.

Observations suggest that variability in oceanographic conditions in the Arctic is very largely driven by the consequences of the flows through open passages to both Atlantic and Pacific Oceans, which themselves respond to the different and characteristic variability of the circulation patterns of each ocean: each inflow is not only variable in volume of water transported but also in the temperature of the water imported.

The global pattern of atmospheric circulation on Mars shows many superficial similarities to that of Earth, but the root causes are very different.

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.

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.

While different continental configurations, elevations, and atmospheric circulation patterns now prevail on Earth, precluding a return to those exact past conditions, the underlying message is that warming of 4o - 7o will result in a biotically very different world.

The current California drought is bad because for the first time ever, scientists from many different fields see parallel lines of evidence for the influence of human - induced climate changes, including the fingerprints of higher temperatures and changes in the atmospheric circulation patterns.

Explanations evoking ocean and atmospheric circulation patterns radically different from today have been proposed to explain the climate of the mid-Cretaceous; however, there is no scientific consensus on how the Mid-Cretaceous warm climate came about (source: NOAA Paleo Climatology program).

Global circulation patterns were very different when the isthmus of Panama was below sea level.
