Sentences with phrase «net ablation»

In Glacier National Park, North Cascades, Helm Glacier and Place Glacier frequent loss of the entire snowcover by the end of the ablation season has become commonplace (WGMS, 2005 The result is in net ablation throughout the accumulation area causing thinning of the glacier in the accumulation zone.

A warming of 1 degree C is sufficient to raise the equilibrium line (below which net ablation occurs) by fully 300 meters.

Though air temperature has so far remained below freezing, melting has begun to occur, and the glacier is suffering net ablation over its entire surface.

This is a far from insignificant change, amounting to 32 % of the measured net ablation during the short period for which data is available.

Not exact matches

The correlation between annual net balance is higher for ablation season temperature than for accumulation season precipitation.

Annual ice and firn ablation (firn and ice net balance: Mayo et al., 1972) is determined using ablation stakes drilled into the glacier surface and simultaneously checked on the same date in late September.

Comparison between net annual balance for each glacier, and accumulation season and ablation season conditions at NOAA Washington State Division 5 weather stations is presented in Table 5.

Equilibrium line - The boundary between the region on a glacier where there is a net annual loss of ice mass (ablation area) and that where there is a net annual gain (accumulation area).

D denotes change in ice discharge while SMB denotes the net surface mass balance (accumulation minus ablation).

The difference between the accumulation and ablation for a given year describes the annual net mass balance, which corresponds to the change in glacier thickness and volume.

In fact, according to [Moelg and Hardy, 2004] precipitation aids net accumulation much more through the albedo affect, which reduces ablation, than through the mass added directly by snowfall.
