RISDecadal Thermocline Variability in the North Pacific Ocean: Two Pathwaysaround the Subtropical Gyre
Publisher: American Meteorological Society
Abstract: Yearly in situ temperature anomaly data in the North Pacific Ocean for 1961?90 have been analyzed along constant-density surfaces (isopycnals) in order to better describe and understand decadal thermocline variability in ...
Interannual Variability of the Coupled Tropical Pacific Ocean–Atmosphere System Associated with the El Niño–Southern Oscillation
Publisher: American Meteorological Society
Abstract: Upper-ocean temperature and surface marine meteorological observations are used to examine interannual variability of the coupled tropical Pacific climate system. The basinwide structure and evolution of meteorological and ...
Structure and Cycle of Decadal Variability of Upper-Ocean Temperature in the North Pacific
Publisher: American Meteorological Society
Abstract: Yearly upper-ocean in situ temperature anomaly data for the period 1961?90 are analyzed to reveal spatial structure and evolution of decadal variability in the North Pacific Ocean. An EOF analysis has been performed on ...
A Modified Vertical Mixing Parameterization for Its Improved Ocean and Coupled Simulations in the Tropical Pacific
Publisher: American Meteorological Society
Abstract: Climate models suffer from significant biases over the tropical Pacific Ocean, including a too-cold cold tongue and too-warm temperature at the depth of the thermocline. The emergence of model biases can be partly attributed ...
Freshwater Flux (FWF)-Induced Oceanic Feedback in a Hybrid Coupled Model of the Tropical Pacific
Publisher: American Meteorological Society
Abstract: The impacts of freshwater flux (FWF) forcing on interannual variability in the tropical Pacific climate system are investigated using a hybrid coupled model (HCM), constructed from an oceanic general circulation model ...
Interdecadal Change in Properties of El Niño–Southern Oscillation in an Intermediate Coupled Model
Publisher: American Meteorological Society
Abstract: The role of subsurface temperature variability in modulating El Niño?Southern Oscillation (ENSO) properties is examined using an intermediate coupled model (ICM), consisting of an intermediate dynamic ocean model and a sea ...
Effect of Penetrating Momentum Flux over the Surface Boundary/Mixed Layer in a z-Coordinate OGCM of the Tropical Pacific
Publisher: American Meteorological Society
Abstract: A simple scheme is proposed for penetrating atmospheric momentum flux over the ocean surface boundary layer or mixed layer (BL/ML) and is tested in the z-coordinate NOAA/Geophysical Fluid Dynamics Laboratory Modular Ocean ...
An Embedding Method for Improving Interannual Variability Simulations in a Hybrid Coupled Model of the Tropical Pacific Ocean–Atmosphere System
Publisher: American Meteorological Society
Abstract: An embedding approach is developed and tested to improve El Niño?Southern Oscillation (ENSO) simulations in a hybrid coupled model (HCM), focusing on the ocean thermocline effects on sea surface temperature (SST) in the ...
Using Satellite Ocean Color Data to Derive an Empirical Model for the Penetration Depth of Solar Radiation (Hp) in the Tropical Pacific Ocean
Publisher: American Meteorological Society
Abstract: atellite-based ocean color measurements indicate clear evidence for bioclimate interactions in the tropical Pacific associated with El Niño?Southern Oscillation (ENSO). Recent modeling studies have demonstrated that ocean ...
An Empirical Model for Surface Wind Stress Response to SST Forcing Induced by Tropical Instability Waves (TIWs) in the Eastern Equatorial Pacific
Publisher: American Meteorological Society
Abstract: High-resolution space-based observations reveal significant two-way air?sea interactions associated with tropical instability waves (TIWs); their roles in budgets of heat, salt, momentum, and biogeochemical fields in the ...
