Antarctic climate results from a complex mix of oceanic and atmospheric circulation patterns, so there could also be other components affecting the amount
of snow accumulation in the region, Bromwich said.
In this way Antarctica undergoes rapid ice loss followed by periods of slower recuperation depending on regional
rates of snow accumulation.
The weather service posted a winter storm watch from Friday afternoon through Saturday afternoon for Western New York, warning
of snow accumulations of 6 to 12 inches with a few hundredths of an inch of ice possible for Niagara County and northern Erie County.
That doesn't provide a full
picture of snow accumulation, since it doesn't take into account the density of the snow layers that pile on the ice.
David Ullman, a postdoctoral researcher at Oregon State University and lead author on the study, said there are two mechanisms through which ice sheets diminish — dynamically, from the jettisoning of icebergs at the fringes, or by a negative «surface mass balance,» which compares the amount
of snow accumulation relative to melting.
This 2013 GMC Acadia Denali with AWD saved me during a commute in a late - winter storm that included white - out conditions and 2 inches or
more of snow accumulation.
My take would be if that is the result of about 20
years of snow accumulation, there likely is no trace of them ever existing now that another at least thirty years accumulation has occurred.
Streamflow projections indicate timing shifts in all three watersheds, predominantly because of changes in the
dynamics of snow accumulation and melt.
For commercial buildings, condominiums or apartment buildings, the Alberta Building Code states that removal should be considered after 20in or 50
cm of snow accumulation.
Including modeled
rates of snow accumulation and basal melt, the Antarctic ice sheet lost ice at an average rate of 183 ± 94 Gt yr − 1 between 2008 and 2015.
Buoys provide key observations for mapping and attributing summer ice loss: drift, bottom vs. top melt,
amount of snow accumulation, nature of ponds (even if anecdotal from web cams), and thickness of level ice.
Dr. Steffen, recently back from the field there, mentioned on Wednesday that the melting rate in summers in most years since my trip had far outpaced the rate
of snow accumulation.
