RISReevaluation of the Takano–Oonishi Scheme for Momentum Advection on Bottom Relief in Ocean Models
Publisher: American Meteorological Society
Abstract: In the Takano and Oonishi models the finite-difference analog of the nonlinear momentum advection contains the concept of diagonally upward/downward mass and momentum fluxes along the bottom slope, and the generalized ...
A Mechanism for the Formation of the Weddell Polynya in 1974
Publisher: American Meteorological Society
Abstract: The formation of the Weddell Polynya is investigated with a one-dimensional, convective mixed-layer model, using in situ data from late summer 1974 as initial conditions. We propose that a high-salinity mixed layer in ...
SST Variability and Its Mechanism in a Coupled Atmosphere–Mixed Layer Ocean Model
Publisher: American Meteorological Society
Abstract: Interannual SST variability in a coupled atmosphere?mixed layer ocean model is investigated. This model has no El Niño but shows a large interannual SST variability in the tropical Pacific. The basin-scale feature of SST ...
El Niño–Southern Oscillation Simulation at 6000 Years before Present with the MRI-CGCM2.3: Effect of Flux Adjustment
Publisher: American Meteorological Society
Abstract: Modulation of El Niño?Southern Oscillation at the mid-Holocene [6000 yr before present (6 ka)] is investigated with a coupled ocean?atmosphere general circulation model. The model is integrated for 300 yr with 6-ka and ...
Dynamics of the Coastal Oyashio and Its Seasonal Variation in a High-Resolution Western North Pacific Ocean Model
Publisher: American Meteorological Society
Abstract: The Coastal Oyashio (CO) carries the cold, fresh, and relatively light water mass called the Coastal Oyashio Water (COW) westward along the southeastern coast of Hokkaido in winter and spring. To investigate dynamics of ...
Multidecadal-Scale Freshening at the Salinity Minimum in the Western Part of North Pacific: Importance of Wind-Driven Cross-Gyre Transport of Subarctic Water to the Subtropical Gyre
Publisher: American Meteorological Society
Abstract: sing oceanographic observations and an eddy-resolving ice?ocean coupled model simulation from 1955 to 2004, the effects of the wind-driven ocean circulation change that occurred in the late 1970s during multidecadal-scale ...
