RISSensitivity of an Intermediate Ocean–Atmosphere Coupled Model of the Tropical Pacific to Its Oceanic Vertical Structure
Publisher: American Meteorological Society
Abstract: An intermediate ocean?atmosphere coupled model (ICM) of the tropical Pacific is used to investigate the sensitivity of the coupled system to the oceanic vertical structure. The model consists of a three-baroclinic-mode ...
El Niño–La Niña Events Simulated with Cane and Zebiak's Model and Observed with Satellite or In Situ Data. Part I: Model Data Comparison
Publisher: American Meteorological Society
Abstract: The Zebiak and Cane model is used in its ?uncoupled mode,? meaning that the oceanic model component is driven by the Florida State University (FSU) wind stress anomalies over 1980?93 to simulate sea surface temperature ...
Vertically Propagating Annual and Interannual Variability in an OGCM Simulation of the Tropical Pacific Ocean in 1985–94
Publisher: American Meteorological Society
Abstract: The annual and interannual variability in the subthermocline equatorial Pacific is studied in a simulation of the tropical Pacific for the 1985?94 decade using a primitive equation high-resolution model. The study focuses ...
Local Coupled Equatorial Variability versus Remote ENSO Forcing in an Intermediate Coupled Model of the Tropical Atlantic
Publisher: American Meteorological Society
Abstract: The relative roles played by the remote El Niño?Southern Oscillation (ENSO) forcing and the local air?sea interactions in the tropical Atlantic are investigated using an intermediate coupled model (ICM) of the tropical ...
Intraseasonal Tropical Atmospheric Variability Associated with the Two Flavors of El Niño
Publisher: American Meteorological Society
Abstract: he characteristics of intraseasonal tropical variability (ITV) associated with the two flavors of El Niño [i.e., the canonical or eastern Pacific (EP) El Niño and the Modoki or central Pacific (CP) El Niño] are documented ...
El Niño-La Niña Events Simulated with Cane and Zebiak's Model and Observed with Satellite or In Situ Data. Part II: Model Forced with Observations
Publisher: American Meteorological Society
Abstract: Various parameterizations derived from the observations are tested and proposed to improve the skill of the Cane and Zebiak's model in simulating the reality. The model is forced by FSU winds over the period 1980?1993. In ...
ENSO Feedbacks and Associated Time Scales of Variability in a Multimodel Ensemble
Publisher: American Meteorological Society
Abstract: The background state of the equatorial Pacific determines the prevalence of a ?slow? recharge oscillator-type ENSO over a ?fast? quasi-biennial surface-driven ENSO. The first is controlled to a large extent by the thermocline ...
Vertical Structure of an OGCM Simulation of the Equatorial Pacific Ocean in 1985–94
Publisher: American Meteorological Society
Abstract: The vertical structure of the variability in the equatorial Pacific in a high-resolution ocean general circulation model (OGCM) simulation for 1985?94 is investigated. Near the equator the linear vertical modes are estimated ...
Impact of Sea Level Assimilation on ENSO Initialization and Prediction: The Role of the Sea Level Zonal Tilt and Zonal Mean
Publisher: American Meteorological Society
Abstract: t present, most models forecasting the El Niño?Southern Oscillation (ENSO) use data assimilation, which constrains models physics using available observations. In this article, an ENSO model of intermediate complexity is ...
Interactive Feedback between the Tropical Pacific Decadal Oscillation and ENSO in a Coupled General Circulation Model
Publisher: American Meteorological Society
Abstract: The output from a coupled general circulation model (CGCM) is used to develop evidence showing that the tropical Pacific decadal oscillation can be driven by an interaction between the El Niño?Southern Oscillation (ENSO) ...
