RISThe Thinning of Arctic Sea Ice, 1988–2003: Have We Passed a Tipping Point?
Publisher: American Meteorological Society
Abstract: Recent observations of summer Arctic sea ice over the satellite era show that record or near-record lows for the ice extent occurred in the years 2002?05. To determine the physical processes contributing to these changes ...
Assimilation of Ice Concentration in an Ice–Ocean Model
Publisher: American Meteorological Society
Abstract: Ice concentration is a critical parameter of the polar marine environment because of the large effect sea ice has on the surface albedo and heat exchange between the atmosphere and the ocean. Simulations of the energy ...
Arctic Ocean Ice Thickness: Modes of Variability and the Best Locations from Which to Monitor Them
Publisher: American Meteorological Society
Abstract: Model simulations of Arctic sea ice and ocean systems are used to determine the major spatial and temporal modes of variability in the ice thickness. A coupled ice?ocean model is forced with daily NCEP?NCAR reanalysis ...
Numerical Modeling of Seabed Response to Combined Wave Current Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a numerical model is developed to study the dynamic response of a porous seabed to combined wavecurrent loadings. While the Reynoldsaveraged Navier–Stokes equations with kخµ turbulence closure scheme and ...
Microphysical Structure of the Marine Boundary Layer under Strong Wind and Spray Formation as Seen from Simulations Using a 2D Explicit Microphysical Model. Part II: The Role of Sea Spray
Publisher: American Meteorological Society
Abstract: he effect of sea spray on the thermodynamics and microphysical structure of the lowest 400-m layer under strong wind speeds is investigated using a 2D hybrid Lagrangian?Eulerian model with spectral bin microphysics. A large ...
Microphysical Structure of the Marine Boundary Layer under Strong Wind and Sea Spray Formation as Seen from a 2D Explicit Microphysical Model. Part III: Parameterization of Height-Dependent Droplet Size Distribution
Publisher: American Meteorological Society
Abstract: his paper completes a series of studies using a 2D hybrid Lagrangian?Eulerian model to investigate the effect of sea spray on the thermodynamics and microphysics of the hurricane mixed layer. The evolution of the mixed ...
Evaluation of Seven Different Atmospheric Reanalysis Products in the Arctic
Publisher: American Meteorological Society
Abstract: tmospheric reanalyses depend on a mix of observations and model forecasts. In data-sparse regions such as the Arctic, the reanalysis solution is more dependent on the model structure, assumptions, and data assimilation ...
Two Dimensional Model for Pore Pressure Accumulations in the Vicinity of a Buried Pipeline
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we presented an integrated numerical model for the waveinduced residual liquefaction around a buried offshore pipeline. In the present model, unlike previous investigations, two new features were added in ...
Manufacturing of 316L Stainless Steel Die Mold by Hot Embossing Process for Microfluidic Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hot embossing process has emerged as a viable method for producing small, complex, precision parts in low volumes. It provides several advantages such as lowcost for molds, high replication accuracy for microfeatures and ...
Arctic Ice–Ocean Modeling with and without Climate Restoring
Publisher: American Meteorological Society
Abstract: A coupled ice?mixed layer?ocean model is constructed for the Arctic Ocean, the Barents Sea, and the Greenland?Iceland?Norwegian Sea. The model is used to address Arctic numerical modeling with and without climate restoring. ...
