Sentences with phrase «how changes in atmospheric circulation»

Whether the large - scale thermodynamic environment and atmospheric static stability (often measured by Convective Available Potential Energy, CAPE) becomes more favourable for tropical storms depends on how changes in atmospheric circulation, especially subsidence, affect the static stability of the atmosphere, and how the wind shear changes.

Not exact matches

The researchers warn, however, that the future evolution of the AMO remains uncertain, with many factors potentially affecting how it interacts with atmospheric circulation patterns, such as Arctic sea ice loss, changes in solar radiation, volcanic eruptions and concentrations of greenhouse gases in the atmosphere.

They were Jorge Sarmiento, an oceanographer at Princeton University who constructs ocean - circulation models that calculate how much atmospheric carbon dioxide eventually goes into the world's oceans; Eileen Claussen, executive director of the Pew Center for Global Climate Change in Washington, D.C.; and David Keith, a physicist with the University of Calgary in Alberta who designs technological solutions to the global warming problem.

Would somebody here, like to explain to me how we can lose Arctic Sea ice (in part or in whole) without changing the atmospheric circulation patterns?

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.

How do the complex feedbacks change atmospheric circulation patterns, and the interaction of these patterns to changes in ice cap topography (e.g. at the LGM)?

And how much of the hiatus is cloud caused in step changes in ocean and atmospheric circulation.

I will now analyse how the system could work and show that composition changes not involving changes in mass only affect atmospheric volume and circulation patterns and not surface temperature.

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.

Lamont's Ryan Abernathey and Richard Seager are studying how changes in the ocean cause sea surface temperature to vary, and how these anomalies drive changes in atmospheric circulation to create extreme weather events.

How atmospheric and ocean circulation responds to various changes in forcing would need to be detailed if someone wanted to «prove» anthropogenic forcing is involved other than a minor increase in the average surface temperature.

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.

As atmospheric circulation changes, tropical cyclone tracks are bound to change (and models show this), but we have low confidence now in predicting just how they might change.

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:

Three - dimensional (3D) planetary general circulation models (GCMs) derived from the models that we use to project 21st Century changes in Earth's climate can now be used to address outstanding questions about how Earth became and remained habitable despite wide swings in solar radiation, atmospheric chemistry, and other climate forcings; whether these different eras of habitability manifest themselves in signals that might be detected from a great distance; whether and how planets such as Mars and Venus were habitable in the past; how common habitable exoplanets might be; and how we might best answer this question with future observations.

The large uncertainty ranges in atmospheric pCO2 arise from uncertainty in how surface productivity responds to circulation change.
