RISA Global Oceanic Data Assimilation System
Publisher: American Meteorological Society
Abstract: A global oceanic four-dimensional data assimilation system has been developed for use in initializing coupled ocean?atmosphere general circulation models and many other applications. The data assimilation system uses a ...
Seasonal Variability of the Gulf Stream Kinetic Energy
Publisher: American Meteorological Society
Abstract: he seasonal variability of the mean kinetic energy (MKE) and eddy kinetic energy (EKE) of the Gulf Stream (GS) is examined using high-resolution regional ocean model simulations. A set of three numerical experiments with ...
The Sensitivity of a Coupled Atmospheric–Oceanic GCM to Prescribed Low-Level Clouds over the Ocean and Tropical Landmasses
Publisher: American Meteorological Society
Abstract: The sensitivity of a coupled general circulation model (CGCM) to tropical marine stratocumulus (MSc) clouds and low-level clouds over the tropical land is examined. The hypothesis that low-level clouds play an important ...
A Study of ENSO Prediction Using a Hybrid Coupled Model and the Adjoint Method for Data Assimilation
Publisher: American Meteorological Society
Abstract: An experimental ENSO prediction system is presented, based on an ocean general circulation model (GCM) coupled to a statistical atmosphere and the adjoint method of 4D variational data assimilation. The adjoint method is ...
The Role of the Indonesian Throughflow in the Indo–Pacific Climate Variability in the GFDL Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The impacts of the Indonesian Throughflow (ITF) on the tropical Indo?Pacific climate, particularly on the character of interannual variability, are explored using a coupled general circulation model (CGCM). A pair of CGCM ...
Indian Ocean Variability in the GFDL Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The interannual variability of the Indian Ocean, with particular focus on the Indian Ocean dipole/zonal mode (IODZM), is investigated in a 250-yr simulation of the GFDL coupled global general circulation model (CGCM). The ...
Summer Enhancement of Arctic Sea Ice Volume Anomalies in the September-Ice Zone
Publisher: American Meteorological Society
Abstract: AbstractBecause of its persistence on seasonal time scales, Arctic sea ice thickness (SIT) is a potential source of predictability for summer sea ice extent (SIE). New satellite observations of SIT represent an opportunity ...
Biases in the Atlantic ITCZ in Seasonal–Interannual Variations for a Coarse- and a High-Resolution Coupled Climate Model
Publisher: American Meteorological Society
Abstract: sing two fully coupled ocean?atmosphere models?Climate Model version 2.1 (CM2.1), developed at the Geophysical Fluid Dynamics Laboratory, and Climate Model version 2.5 (CM2.5), a new high-resolution climate model based on ...
meeting summary: A Workshop on the MJO and ENSO
Publisher: American Meteorological Society
Abstract: A workshop was held 15?17 March 2000 to discuss the possibility that the Madden?Julian oscillation (MJO) interacts with El Niño?Southern Oscillation (ENSO). The workshop explored a number of topics related to the MJO?ENSO ...
ENSO Modulation: Is It Decadally Predictable?
Publisher: American Meteorological Society
Abstract: bservations and climate simulations exhibit epochs of extreme El Niño?Southern Oscillation (ENSO) behavior that can persist for decades. Previous studies have revealed a wide range of ENSO responses to forcings from ...
