Initial Conditions for a General Circulation Model of Tropical Oceans
Initial Conditions General Circulation Model Tropical Oceans
2009/1/6
A general circulation model of the tropical Pacific Ocean, which realistically simulates El Niño of 1982–83, has been used to determine how different initial conditions affect the model. Given ...
The Use of Mean Atmospheric Parameters in the Calculation of Modeled Mean Surface Heat Fluxes over the World’s Oceans
Mean Atmospheric Parameters World’s Oceans Surface Heat Fluxes
2008/12/30
There are a number of atlases that display the distribution of ocean-atmosphere sensible and latent heat fluxes over various regions. Many are based on the “classical” method, in which time mean quant...
On the Contrast between the Seasonal Cycles of the Equatorial Atlantic and Pacific Oceans
Seasonal Cycles Equatorial Atlantic Pacific Oceans
2008/12/24
Although the winds on the equator at 28°W in the Atlantic and 140°W in the Pacific have similar seasonal variations, the current fluctuations have pronounced differences. In the Pacific the maximum sp...
Latent and Sensible Heat Flux Anomalies over the Northern Oceans：Driving the Sea Surface Temperature
sea level pressure sea surface temperature
2008/12/22
A part of the large-scale thermodynamic forcing of the upper ocean is examined by relating monthly anomalous latent and sensible heat flux to changes in sea surface temperature (SST) anomalies over th...
The global distribution of freshwater transport in the ocean is presented, based on an integration point at Bering Strait, which connects the Pacific and Atlantic oceans via the Artic Ocean. Through B...
Dynamic Excitation of Internal Gravity Waves in the Equatorial Oceans
internal gravity waves Equatorial Oceans
2008/12/11
It is proposed that shear instability of the upper flank of the equatorial undercurrent may generate, under a broad range of conditions, downward propagating internal gravity waves (IGW) of large ampl...
Propagation and Decay of Forced and Free Baroclinic Rossby Waves in Off-Equatorial Oceans
sea surface height global ocean general circulation model
2008/12/3
Baroclinic Rossby wave motions in the off-equatorial oceans are investigated with emphasis on how eddy dissipation can influence the propagation of the height anomalies when both the forced wave respo...
A Neutral Density Variable for the World’s Oceans
Neutral Density Variable World’s Oceans oceanographic data
2008/11/12
The use of density surfaces in the analysis of oceanographic data and in models of the ocean circulation is widespread. The present best method of fitting these isopycnal surfaces to hydrographic data...
Heat and Buoyancy Budgets and Mixing Rates in the Upper Thermocline of the Indian and Global Oceans
Buoyancy Budgets Global Oceans Upper Thermocline Mixing Rates
2008/10/23
Diapycnal and diathermal diffusivity values in the upper thermocline are estimated from buoyancy and heat budgets for water volumes bounded by isopycnals and isotherms, the air–sea interface, and coas...
Why Western Boundary Currents in Realistic Oceans are Inviscid: A Link between Form Stress and Bottom Pressure Torques
Western Boundary Currents Realistic Oceans Link Bottom Pressure Torques
2008/7/31
It is shown that wind stress curl is balanced by bottom pressure torque in a zonal integral over any strip wide enough to smooth out the effect of nonlinear terms (typically about 3° of latitude). The...
Interannual Dynamics and Thermodynamics of the Indo–Pacific Oceans
Interannual Dynamics Thermodynamics Indo–Pacific Oceans
2008/6/30
A global ocean circulation model, driven by observed interannual fluxes, is used to gain insight into how sea surface temperature anomalies (SSTAs, i.e., variations from the mean seasonal signal) in t...
Seasonal Heat Budgets of the North Pacific and North Atlantic Oceans
Seasonal Heat Budgets North Pacific North Atlantic Oceans
2008/6/25
Here, seasonal heat transport in the North Pacific and North Atlantic Oceans is compared using a 49-year-long analysis based on data assimilation. In midlatitudes surface heat flux is largely balanced...
Vertically homogeneous variable-temperature layer models are often used to describe upper-ocean variability, the dynamics of jets and fronts included. Frontogenesis is known to have a preference for s...
Interior Communication from the Subtropical to the Tropical Oceans
Interior Communication Subtropical Tropical Oceans
2008/6/9
The communication from the subtropical gyre interior to the Tropics is examined using wind stress datasets and results from an ocean data assimilation system. It is shown that the interior communicati...
Is There a Meridional Overturning Cell in the Pacific and Indian Oceans
Meridional Overturning Cell Pacific Indian Oceans
2008/6/9
The diagnostic quasi-island model of Nof addressing the exchange between the South Atlantic and the Southern Ocean is extended to the exchange between the Pacific–Indian Ocean system and the Southern ...
