RISCauses of Decadal Changes of the Freshwater Content in the Arctic Ocean
Publisher: American Meteorological Society
Abstract: ecadal changes of the liquid freshwater content in the Arctic Ocean are studied with a suite of forward and adjoint model simulations. Adjoint sensitivities show that freshwater volume changes in the Norwegian Atlantic ...
Three-Dimensional Chaotic Advection by Mixed Layer Baroclinic Instabilities
Publisher: American Meteorological Society
Abstract: hree-dimensional (3D) finite-time Lyapunov exponents (FTLEs) are computed from numerical simulations of a freely evolving mixed layer (ML) front in a zonal channel undergoing baroclinic instability. The 3D FTLEs show a ...
Causes of Changes in the Denmark Strait Overflow
Publisher: American Meteorological Society
Abstract: The warming Nordic seas potentially tend to decrease the overflow across the Greenland?Iceland?Scotland Ridge (GISR) system. Recent observations by Macrander et al. document a significant drop in the intensity of outflowing ...
Modified Halocline Water over the Laptev Sea Continental Margin: Historical Data Analysis
Publisher: American Meteorological Society
Abstract: istorical hydrographic data (1940s?2010) show a distinct cross-slope difference of the lower halocline water (LHW) over the Laptev Sea continental margins. Over the slope, the LHW is on average warmer and saltier by 0.2°C ...
