Mesoscale Eddies Are Oases for Higher Trophic Marine Life
(Public Library of Science, 2012-01-17)
<p>Mesoscale eddies stimulate biological production in the ocean, but knowledge of energy transfers to higher trophic levels within eddies remains fragmented and not quantified. Increasing the knowledge base is constrained ...
Cover ERS-1/2 SAR monitoring of dangerous ice phenomena along the western part of Northern Sea Route
(Taylor & Francis, 1997-08-01)
Surface Atmospheric Temperature as Indicator of Climate Change in the Arctic
(Nansen Environmental and Remote Sensing Center, 2005-12)
Surface atmospheric temperature (SAT) is one of the most reliable atmospheric characteristics used to quantify climate change. Contrary to what has been always implicitly assumed, changes in the SAT have loose relations ...
The Influence of large convective eddies on the surface-layer turbulence
(Royal Meteorological Society, 2006-06)
Close to the surface large coherent eddies consisting of plumes and downdraughts cause convergent winds blowing towards the plume axes, which in turn cause wind shears and generation of turbulence. This mechanism strongly ...
Open Boundary Conditions for the Extended Kalman Filter With a Quasi-Geostrophic Ocean Model
(American Geophysical Union, 1993-05-18)
The formulation of consistent boundary conditions for the quasi-geostrophic (QG) model with an extended Kaiman filter in a data assimilation scheme is discussed. To form a well-posed boundary value problem for the QG model, ...
Future climate change: Modeling and scenarios for the Arctic
Sensitivity of simulated wintertime Arctic atmosphere to vertical resolution in the ARPEGE/IFS model
(Springer Verlag, 2007-10-16)
The current state of the art general circulation models, including several of those used by the IPCC, show considerable disagreement in simulating present day high latitude climate. This is of major concern and reduces the ...
Towards a more saline North Atlantic and a fresher Arctic under global warming
(American Geophysical Union, 2006-11-14)
Most atmosphere-ocean general circulation models (GCMs) forced with increasing greenhouse gas concentrations predict enhanced atmospheric moisture transports to the high northern latitudes. Together with melting of ...
On effect of wave breaking on short wind waves
(American Geophysical Union, 2004-10)
The paper presents an attempt to estimate short wave generation by wave breaking. A breaking wave crest disturbs the surface and generates sub-surface turbulence. The locally disturbed area further disperses and feeds short ...
Subpolar Gyre Index and the North Atlantic Meridional Overturning Circulation in a Coupled Climate Model
(Institute of Atmospheric Physics, Chinese Academy of Sciences, 2008-11-16)
The subpolar gyre index (SPG), derived from the analysis of sea surface height (SSH), is proposed to be a potential indicator for the North Atlantic Meridional Overturning Circulation (AMOC) based on observation as well ...
