RISA Recent Shift in the Monsoon Centers Associated with the Tropospheric Biennial Oscillation
Publisher: American Meteorological Society
Abstract: AbstractThe tropospheric biennial oscillation (TBO) is conventionally considered to involve transitions between the Indian and Australian summer monsoons and the interactions between these two monsoons and the underlying ...
A 10–15-Yr Modulation Cycle of ENSO Intensity
Publisher: American Meteorological Society
Abstract: This study examines the slow modulation of El Niño?Southern Oscillation (ENSO) intensity and its underlying mechanism. A 10?15-yr ENSO intensity modulation cycle is identified from historical and paleoclimate data by ...
Linking Centennial Surface Warming Patterns in the Equatorial Pacific to the Relative Strengths of the Walker and Hadley Circulations
Publisher: American Meteorological Society
Abstract: his study analyzes representative concentration pathway 4.5 projections by 18 models from phase 5 of the Coupled Model Intercomparison Project to show that surface warming patterns in the equatorial Pacific during the ...
A Recent Shift in the Monsoon Centers Associated with the Tropospheric Biennial Oscillation
Publisher: American Meteorological Society
Abstract: AbstractThe tropospheric biennial oscillation (TBO) is conventionally considered to involve transitions between the Indian and Australian summer monsoons and the interactions between these two monsoons and the underlying ...
The Influences of the Atlantic Multidecadal Oscillation on the Mean Strength of the North Pacific Subtropical High during Boreal Winter
Publisher: American Meteorological Society
Abstract: AbstractThe Atlantic multidecadal oscillation (AMO) has been shown to be capable of exerting significant influences on the Pacific climate. In this study, the authors analyze reanalysis datasets and conduct forced and ...
Zonal Flow Vacillation and Eddy Forcing in a Simple GCM of the Atmosphere
Publisher: American Meteorological Society
Abstract: Zonal flow vacillation with very long time scales is observed in a 3070-day simple GCM simulation with zonally symmetric forcing. The long lasting zonal wind anomalies suggest that zonal flow vacillation is self-maintained. ...
Contrasting Eastern-Pacific and Central-Pacific Types of ENSO
Publisher: American Meteorological Society
Abstract: Surface observations and subsurface ocean assimilation datasets are examined to contrast two distinct types of El Niño?Southern Oscillation (ENSO) in the tropical Pacific: an eastern-Pacific (EP) type and a central-Pacific ...
Orographic Influences on the Distribution and Generation of Atmospheric Variability in a GCM
Publisher: American Meteorological Society
Abstract: The effect of large-scale mountains on atmospheric variability is studied in a series of GCM experiments in which a single mountain is varied in height from 0 to 4 km. High-frequency (τ < 7 days) and low-frequency (τ > 30 ...
Interannual Variations in the Southwest U.S. Monsoon and Sea Surface Temperature Anomalies: A General Circulation Model Study
Publisher: American Meteorological Society
Abstract: The interannual variability in the southwest U.S. monsoon and its relationship to sea surface temperature (SST) anomalies is investigated via experiments conducted with the University of California, Los Angeles, atmospheric ...
A Discussion on the Errors in the Surface Heat Fluxes Simulated by a Coupled GCM
Publisher: American Meteorological Society
Abstract: This paper contrasts the sea surface temperature (SST) and surface heat flux errors in the Tropical Pacific simulated by the University of California, Los Angeles, coupled atmosphere?ocean general circulation model (CGCM) ...
