Analytical Study of an Isotropic Viscoplastic Sea Ice Model in Idealized Configurations
Publisher: American Meteorological Society
Abstract: nalytic solutions of a mechanical sea ice model are computed in idealized configurations. They are then used to study the properties of this model. It classically assumes that the ice behaves at large scale as an isotropic ...
Winter Coastal Divergence as a Predictor for the Minimum Sea Ice Extent in the Laptev Sea
Publisher: American Meteorological Society
Abstract: Seasonal predictability of the minimum sea ice extent (SIE) in the Laptev Sea is investigated using winter coastal divergence as a predictor. From February to May, the new ice forming in wind-driven coastal polynyas grows ...
Disentangling Dynamic from Thermodynamic Summer Ice Area Loss from Observations (1979–2021): A Potential Mechanism for a “First-Time” Ice-Free Arctic
Publisher: American Meteorological Society
The Continuum of Northern Hemisphere Teleconnection Patterns and a Description of the NAO Shift with the Use of Self-Organizing Maps
Publisher: American Meteorological Society
Abstract: In this study, the method of self-organizing maps (SOMs) is used with NCEP?NCAR reanalysis data to advance the continuum perspective of Northern Hemisphere teleconnection patterns and to shed light on the secular eastward ...
Subseasonal Predictability of Arctic Ocean Sea Ice Conditions: Bering Strait and Ekman-Driven Ocean Heat Transport
Publisher: American Meteorological Society
Vertical Heat Fluxes beneath Idealized Sea Ice Leads in Large-Eddy Simulations: Comparison with Observations from the SHEBA Experiment
Publisher: American Meteorological Society
Abstract: Large-eddy simulations (Δx = Δz = 1 m) are used to examine vertical ocean heat fluxes driven by mechanical and buoyancy forcing across idealized sea ice leads. Forcing parameters approximate conditions from a shear event ...
Predictability of the Minimum Sea Ice Extent from Winter Fram Strait Ice Area Export: Model versus Observations
