seasonal ice loss.

The
seasonal atmospheric response to projected sea
ice loss in the late twenty - first century.
Judah Cohen, a climate forecaster at Atmospheric and Environmental Research in Massachusetts, who issues
seasonal snowfall forecasts several months in advance for his company's clients, said the relationship between sea
ice loss and the Arctic Oscillation is a key area for future research to focus on.
However if we have a similar profile of volume
loss as in the preceding two years then random variability looks very unlikely and I'll be veering to the following viewpoint — that something new and radical has happened in the
seasonal cycle of sea -
ice loss, a new factor that in principle could have the power to make a virtually sea
ice free state in September plausible this decade.
It is likely that the primary reason for the large
loss of
ice this summer is that the
ice cover has continued to thin and become more dominated by
seasonal ice.
It seems clear that the SSTAs are a function of
seasonal sea
ice loss at the surface.
Although that's really all that needs be said, I should add that jetfuel is trying to compare cumulative year - over-year land
ice mass
loss in Antarctica with (cyclical)
seasonal river / lake
ice volume gain in Canada - and ignoring the inevitable melt - away of the latter.
As far as am I serious, I was comparing to the
seasonal N.A. lake
ice because 81 out of 26.45 million gigatonnes isn't an appreciative amount of
loss.
Evidence suggests that the negative phase of the Arctic Oscillation was driven in part by warm air (air warmed by the dramatic
seasonal loss of Arctic sea
ice) 9 as well as by changes in snow cover over Eurasia driven by climate change.10 This event is part of an emerging trend in which a warming climate may paradoxically bring colder, snowier winters to northern Europe and the eastern United States.11
Overall, the curve shown in Figure 4 is commensurate with the notion that a thinner arctic
ice cover that is more mobile can lead to greater
seasonal and interannual variability, with a potential
loss in predictability.
This partly explains why the
seasonal loss and growth of Antarctic sea
ice is more dramatic than its Arctic counterpart.
Different
seasonal progressions of summer sea
ice loss are apparent in daily time series of sea
ice extent from different years (Figure 4).
Interestingly this year, while July
ice loss rates were rapid in the central Arctic, melt out of the
seasonal ice in Hudson and Baffin bays was slow with the
ice cover persisting longer than in recent years.
Judah Cohen, a climate forecaster at Atmospheric and Environmental Research in Massachusetts, who issues
seasonal snowfall forecasts several months in advance for his company's clients, said the relationship between sea
ice loss and the Arctic Oscillation is a key area for future research to focus on.
This is twice the 2001 heat flux, comparable to the annual shortwave radiative flux into the Chukchi Sea, and enough to melt 1 / 3rd of the 2007
seasonal Arctic sea -
ice loss.
The
loss of multi-year
ice during 2007 has resulted in all the minima since then being well below normal, with a high amplitude
seasonal cycle.
