RISImpacts of the Oyashio Temperature Front on the Regional Climate
Publisher: American Meteorological Society
Abstract: mpacts of a sea surface temperature front (SSTF) in the northwestern Pacific Ocean on the large-scale summer atmospheric state in the region are examined with a regional atmospheric circulation model developed at the ...
Wavelet Analysis and Ocean Modeling: A Dynamically Adaptive Numerical Method “WOFD-AHO”
Publisher: American Meteorological Society
Abstract: Wavelet analysis provides information on the energy present at various scales and locations throughout a computational domain. This information is precisely the information that is needed to define the appropriate gridpoint ...
Influences of Atlantic Climate Change on the Tropical Pacific via the Central American Isthmus
Publisher: American Meteorological Society
Abstract: Recent global coupled model experiments suggest that the atmospheric bridge across Central America is a key conduit for Atlantic climate change to affect the tropical Pacific. A high-resolution regional ocean?atmosphere ...
Vertical Mixing in the Ocean and Its Impact on the Coupled Ocean–Atmosphere System in the Eastern Tropical Pacific
Publisher: American Meteorological Society
Abstract: The zonal and meridional asymmetries in the eastern tropical Pacific (the eastern equatorial cold tongue and the northern intertropical convergence zone) are key aspects of the region that are strongly influenced by ...
Dynamics of Biweekly Oscillations in the Equatorial Indian Ocean
Publisher: American Meteorological Society
Abstract: Variability of the wind field over the equatorial Indian Ocean is spread throughout the intraseasonal (10?60 day) band. In contrast, variability of the near-surface ? field in the eastern, equatorial ocean is concentrated ...
An Objective Method for Probabilistic Forecasting of Multimodal Kuroshio States using Ensemble Simulation and Machine Learning
Publisher: American Meteorological Society
Abstract: This paper presents a method for detecting the ensemble means, spreads, and occurrence probabilities for each of the multiple Kuroshio states. This is accomplished by classifying the forecasts of the ensemble members with ...
Dynamics of a Quasi-Stationary Jet along the Subarctic Front in the North Pacific Ocean (the Western Isoguchi Jet): An Ideal Two-Layer Model
Publisher: American Meteorological Society
Abstract: ABSTRACTThe dynamics of a quasi-stationary jet along the Subarctic Front in the North Pacific Ocean (the Western Isoguchi Jet) were investigated using an idealized two-layer model. The experiments suggested that a seafloor ...
Systematic Errors in South Asian Monsoon Simulation: Importance of Equatorial Indian Ocean Processes
Publisher: American Meteorological Society
Abstract: AbstractForecasting monsoon rainfall using dynamical climate models has met with little success, partly due to models? inability to represent the monsoon climatological state accurately. In this article the nature and ...
What Maintains the SST Front North of the Eastern Pacific Equatorial Cold Tongue?
Publisher: American Meteorological Society
Abstract: A coupled ocean?atmosphere regional model suggests a mechanism for formation of a sharp sea surface temperature (SST) front north of the equator in the eastern Pacific Ocean in boreal summer and fall. Meridional convergence ...
A Regional Ocean–Atmosphere Model for Eastern Pacific Climate: Toward Reducing Tropical Biases
Publisher: American Meteorological Society
Abstract: The tropical Pacific Ocean is a climatically important region, home to El Niño and the Southern Oscillation. The simulation of its climate remains a challenge for global coupled ocean?atmosphere models, which suffer large ...
