RISDynamical Initialization for the Numerical Forecasting of Ocean Surface Circulations Using a Variational Assimilation System
Publisher: American Meteorological Society
Abstract: A variational data assimilation system is presented for the initialization of an ocean surface circulation forecast system. The authors? variational data assimilation system is designed to satisfy both statistical and ...
Influence of Local Dynamical Air–Sea Feedback Process on the Hawaiian Lee Countercurrent
Publisher: American Meteorological Society
Abstract: ocal air?sea interactions over the high sea surface temperature (SST) band along the Hawaiian Lee Countercurrent (HLCC) are examined with a focus on dynamical feedback of SST-induced wind stress to the ocean using the ...
EFSO at Different Geographical Locations Verified with Observing System Experiments

Air–Sea Heat Exchanges Characteristic of a Prominent Midlatitude Oceanic Front in the South Indian Ocean as Simulated in a High-Resolution Coupled GCM
Publisher: American Meteorological Society
Abstract: An integration of a high-resolution coupled general circulation model whose ocean component is eddy permitting and thus able to reproduce a sharp gradient in sea surface temperature (SST) is analyzed to investigate air?sea ...
Seasonal Evolutions of Atmospheric Response to Decadal SST Anomalies in the North Pacific Subarctic Frontal Zone: Observations and a Coupled Model Simulation
Publisher: American Meteorological Society
Abstract: otential impacts of pronounced decadal-scale variations in the North Pacific sea surface temperature (SST) that tend to be confined to the subarctic frontal zone (SAFZ) upon seasonally varying atmospheric states are ...
Emergence of Wind-Driven Near-Inertial Waves in the Deep Ocean Triggered by Small-Scale Eddy Vorticity Structures
Publisher: American Meteorological Society
Abstract: sing numerical simulations forced by a uniform realistic wind time series, the authors show that the presence of a mesoscale eddy field at midlatitudes accelerates the vertical propagation of the wind-forced near-inertial ...
Ensemble-Based Atmospheric Reanalysis Using a Global Coupled Atmosphere–Ocean GCM
Publisher: American Meteorological Society
Abstract: ABSTRACTEnsemble-based atmospheric data assimilation (DA) systems are sometimes afflicted with an underestimation of the ensemble spread near the surface caused by the use of identical boundary conditions for all ensemble ...
