RISDetection of an Annual Westward Propagating Signal in the Meridional Wind Component along 8°N in the Pacific
Publisher: American Meteorological Society
Abstract: A westward propagating signal with the annual period is detected in anomalies of the zonally averaged meridional wind component along 8°N across the Pacific Ocean. The propagating signal in the ?eddy? (defined as the ...
Buoyancy- and Wind-Driven Circulation in an Extended Model of Potential Vorticity Homogenization
Publisher: American Meteorological Society
Abstract: An analytical model is proposed on the middepth water circulation between the surface wind-driven circulation and the deep buoyancy-driven circulation. The model consists of three and a half layers, with the second and ...
Storm-Track Response to SST Fronts in the Northwestern Pacific Region in an AGCM
Publisher: American Meteorological Society
Abstract: he storm-track response to sea surface temperature (SST) fronts in the northwestern Pacific region is investigated using an atmospheric general circulation model with a 50-km horizontal resolution. The following two ...
Decadal Response of the Kuroshio Extension Jet to Rossby Waves: Observation and Thin-Jet Theory
Publisher: American Meteorological Society
Abstract: his study examines interannual to decadal variability of the Kuroshio Extension (KE) jet using satellite altimeter observations from 1993 to 2010. The leading empirical orthogonal function (EOF) mode of sea level variability ...
Response of Storm Tracks to Bimodal Kuroshio Path States South of Japan
Publisher: American Meteorological Society
Abstract: large meridional shift of the sea surface temperature front occurs off the south coast of Japan associated with transitions between the large-meander and straight paths of the Kuroshio. Most extratropical cyclones generated ...
Maximal Wavelet Filter and Its Application to Bidecadal Oscillation over the Northern Hemisphere through the Twentieth Century
Publisher: American Meteorological Society
Abstract: Based on a wavelet transform, a new method referred to as maximal wavelet filter (MWF) is proposed to extract temporal structure changes of a climatic oscillation, which varies its pattern corresponding to the changes of ...
Interannual to Interdecadal Variability in the Japan Sea Based on a New Gridded Upper Water Temperature Dataset
Publisher: American Meteorological Society
Abstract: A new gridded water temperature dataset of upper 400-m depths (0, 50, 100, 200, 300, and 400 m) for the Japan Sea (or East Sea) is produced by using an optimal interpolation technique from 1930 to 1996, based on oceanographic ...
Sea Level Variability around Japan during the Twentieth Century Simulated by a Regional Ocean Model
Publisher: American Meteorological Society
Abstract: AbstractSea level variability around Japan from 1906 to 2010 is examined using a regional ocean model, along with observational data and the CMIP5 historical simulations. The regional model reproduces observed interdecadal ...
Precipitation Response to the Gulf Stream in an Atmospheric GCM
Publisher: American Meteorological Society
Abstract: The precipitation response to sea surface temperature (SST) gradients associated with the Gulf Stream is investigated using an atmospheric general circulation model. Forced by observed SST, the model simulates a narrow ...
Coupled Ocean–Atmosphere Response to Idealized Freshwater Forcing over the Western Tropical Pacific
Publisher: American Meteorological Society
Abstract: The coupled ocean?atmosphere responses to idealized freshwater forcing in the western tropical Pacific are studied using a fully coupled climate model. The model explicitly demonstrates that freshwater forcing in the western ...
