What the climate models were missing, she said, was the strong brine production
from sea ice formation in the Bering Sea.
Not exact matches
«A sort of grand problem in Earth science is to understand the water cycle — evaporation
from the ocean, clouds, rain, the
formation of
ice, the runoff
from the land back into the
sea,» said Eric Lindstrom, Aquarius program scientist at NASA.
They are called polynyas,
formations that derive their name
from the Russian word for «hole in the
ice,» and are typically an expanse of open seawater along the coast that is enclosed by floating
sea ice and the continental shelf.
Arctic winter
formation has been largely hit by advection
from cyclones easily punching through what was once a mighty fortress of cold air living in a physical symbiosis with much thicker
sea ice.
The retreat of the Arctic
sea ice in recent decades is moving the egdge of the
sea ice away
from the areas of deep water
formation and I would have thought that this would contribute to a weakening of amoc south of Greenland.
The late
formation of
ice from the Beaufort, Chukchi, East Siberian, and Bering
Seas should be visible in the NOAA animations.
The study, published in the journal Nature Geosciences, suggests that the change of phase of the Interdecadal Pacific Oscillation (IPO)
from positive to negative, or vice versa, could initiate chain reaction of climate impact that may affect the
sea ice formation in the Antarctic region.
-LRB-- NAO) This
sea ice then melts in the Sub Polar Atlantic, releasing fresh water into the sub - polar Atlantic waters, which in turn impedes the
formation of NADW, which slows down the thermohaline circulation causing warm air not to be brought up
from the lower latitudes as far north as previous while in lessening amounts.
I mistakenly believed the increase in
ice formation resulted
from some combination of colder
sea water and air.
To summarise the arguments presented so far concerning
ice - loss in the arctic basin, at least four mechanisms must be recognised: (i) a momentum - induced slowing of winter
ice formation, (ii) upward heat - flux
from anomalously warm Atlantic water through the surface low ‐ salinity layer below the
ice, (iii) wind patterns that cause the export of anomalous amounts of drift
ice through the Fram Straits and disperse pack -
ice in the western basin and (iv) the anomalous flux of warm Bering
Sea water into the eastern Arctic of the mid 1990s.
With the use of a climate model of intermediate complexity, we demonstrate that with mwp - 1A originating
from the Antarctic
Ice Sheet, consistent with recent
sea - level fingerprinting inferences, the strength of North Atlantic Deep Water (NADW)
formation increases, thereby warming the North Atlantic region and providing an explanation for the onset of the Bølling - Allerød warm interval.
