The Response of Tropical Climate to the Equatorial Emergence of Spiciness Anomalies
Publisher: American Meteorological Society
Abstract: The ocean?atmosphere response to the surfacing of temperature anomalies from the oceanic thermocline is a key process in climate variability with decadal time scales. Using a coupled general circulation model, it is shown ...
Scale and Rossby Number Dependence of Observed Wind Responses to Ocean-Mesoscale Sea Surface Temperatures
Publisher: American Meteorological Society
Abstract: The horizontal scale dependences of in-phase and lagged imprints of ocean-mesoscale sea surface temperatures on surface winds are investigated using daily AMSR-E radiometer and QuikSCAT scatterometer observations in the ...
The Indonesian Throughflow and the Global Climate System
Publisher: American Meteorological Society
Abstract: The role of the Indonesian Throughflow in the global climate system is investigated with a coupled ocean?atmosphere model by contrasting simulations with realistic throughflow and closed Indonesian passages. The Indonesian ...
The Atmospheric Response to Weak Sea Surface Temperature Fronts
Publisher: American Meteorological Society
Abstract: he response of the atmospheric boundary layer to fronts of sea surface temperature (SST) is characterized by correlations between wind stress divergence and the downwind component of the SST gradient and between the wind ...
Origin of Decadal-Scale, Eastward-Propagating Heat Content Anomalies in the North Pacific
Publisher: American Meteorological Society
Abstract: pper ocean heat content (OHC) is at the heart of natural climate variability on interannual-to-decadal time scales, providing climate memory and the source of decadal prediction skill. In the midlatitude North Pacific ...
The Meridional and Seasonal Structures of the Mixed-Layer Depth and its Diurnal Amplitude Observed during the Hawaii-to-Tahiti Shuttle Experiment
Publisher: American Meteorological Society
Abstract: We describe the meridional and seasonal structures of daily mean mixed-layer depth and its diurnal amplitude and their relation to atmospheric fluxes by compositing mixed-layer depth estimates derived from density observations. ...
The Competition of Freshwater and Radiation in Forcing the Ocean during El Niño
Publisher: American Meteorological Society
Abstract: The relative roles of heat and freshwater fluxes in forcing the tropical Pacific on interannual timescales are investigated using sophisticated atmospheric and oceanic general circulation models. Interannual density flux ...
The Forcing of the Pacific Decadal Oscillation
Publisher: American Meteorological Society
Abstract: The Pacific decadal oscillation (PDO), defined as the leading empirical orthogonal function of North Pacific sea surface temperature anomalies, is a widely used index for decadal variability. It is shown that the PDO can ...
Influence of Low-Frequency Indonesian Throughflow Transport on Temperatures in the Indian Ocean in a Coupled Model
Publisher: American Meteorological Society
Abstract: The relationship between 3- and 10-yr variability in Indian Ocean temperatures and Indonesian throughflow (ITF) volume transport is examined using results from a 300-yr integration of the coupled NCAR Parallel Climate Model ...
Decadal Shifts of the Kuroshio Extension Jet: Application of Thin-Jet Theory
Publisher: American Meteorological Society
Abstract: eridional shifts of the Kuroshio Extension (KE) jet on decadal time scales are examined using a 1960?2004 hindcast simulation of an eddy-resolving ocean general circulation model for the Earth Simulator (OFES). The leading ...
