and the majority of the earths glaciers are losing mass too.
Canadian Ice Service, 4.7, Multiple Methods As with CIS contributions in June 2009, 2010,
and 2011, the 2012 forecast was derived using a combination of three methods: 1) a qualitative heuristic method based on observed end - of - winter
arctic ice thicknesses
and extents, as well as an examination of Surface Air Temperature (SAT), Sea Level Pressure (SLP)
and vector wind anomaly patterns
and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September
Arctic Ice Extent time series into the future;
and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests
ocean,
atmosphere and sea ice predictors.
Sea ice is lost due to increasing
ocean heat transport into the
arctic and the resulting loss of ice causes the
atmosphere to warm.
Zhakarov's model is conceptually simple: during periods of high precipitation when winter ice forms readily, summer ice cover increases, the
atmosphere cools, the
arctic front together with its associated rain belt shifts south so that freshwater input to the
Arctic Ocean decreases,
and winter ice cover is thicker, has a deeper draft,
and so survives better in summer.
