An Eddy Parameterization Based on Maximum Entropy Production with Application to Modeling of the Arctic Ocean Circulation
Publisher: American Meteorological Society
Abstract: An eddy parameterization derived from statistical mechanics of potential vorticity is applied for inviscid shallow-water equations. The solution of a variational problem based on the maximum entropy production (MEP) principle ...
Tides in the Sea of Okhotsk
Publisher: American Meteorological Society
Abstract: Eight major tidal constituents in the Sea of Okhotsk have been investigated using a numerical solution of tidal equations on a 5? space grid. The tides are dominated by the diurnal constituents. Diurnal tidal currents are ...
Modulated Trends in Arctic Surface Air Temperature Extremes as a Fingerprint of Climate Change
Publisher: American Meteorological Society
Role of Polar Amplification in Long-Term Surface Air Temperature Variations and Modern Arctic Warming
Publisher: American Meteorological Society
Abstract: This study uses an extensive dataset of monthly surface air temperature (SAT) records (including previously unutilized) from high-latitude (>60°N) meteorological land stations. Most records have been updated by very recent ...
Warming of the Intermediate Atlantic Water of the Arctic Ocean in the 2000s
Publisher: American Meteorological Society
Abstract: his analysis evaluates the thermal state of the intermediate (depth range of 150?900 m) Atlantic Water (AW) of the Arctic Ocean, beginning in the 1950s and with particular focus on the transition from the 1990s to the 2000s ...
Divergence in Climate Model Projections of Future Arctic Atlantification
Publisher: American Meteorological Society
Winter Convection Transports Atlantic Water Heat to the Surface Layer in the Eastern Arctic Ocean
Publisher: American Meteorological Society
Abstract: 1-yr (2009/10) record of temperature and salinity profiles from Ice-Tethered Profiler (ITP) buoys in the Eurasian Basin (EB) of the Arctic Ocean is used to quantify the flux of heat from the upper pycnocline to the surface ...
Eastern Arctic Ocean Diapycnal Heat Fluxes through Large Double-Diffusive Steps
Publisher: American Meteorological Society
Abstract: The diffusive layering (DL) form of double-diffusive convection cools the Atlantic Water (AW) as it circulates around the Arctic Ocean. Large DL steps, with heights of homogeneous layers often greater than 10 m, have been ...
Intermittent Intense Turbulent Mixing under Ice in the Laptev Sea Continental Shelf
Publisher: American Meteorological Society
Abstract: Vertical mixing in the bottom boundary layer and pycnocline of the Laptev Sea is evaluated from a rapidly sampled 12-h time series of microstructure temperature, conductivity, and shear observations collected under 100% ...
