Abstract: A simple, quasigeostrophic, two-layer model was used to study the interactions of two like-signed vortices and streamer development in the ocean. In particular, models corresponding to the observed merger of two Kuroshio ...

Abstract: Modification and distribution of North Pacific Intermediate Water (NPIW) in the area north of 30°N and east of 150°E are discussed based on an isopycnal particle tracking experiment with the velocity field estimated from ...

Abstract: This study investigates the distribution of the sea surface height anomaly (SSHA) with the aim of quantifying the characteristics of mesoscale eddies in the Kuroshio?Oyashio extension region (KOER), where intense mesoscale ...

Abstract: A linear stability analysis was conducted for a three-layer primitive equation model including viscosity with a basic state, which modeled the stratification and velocity fields with the vertical and horizontal variations ...

Abstract: The intrusion of western boundary currents (WBC) across the wind-driven gyre boundary and associated cross-gyre transport are examined using layered numerical models with realistic topography and annual mean wind stress, ...

Abstract: Seasonal variations of the Oyashio near the east coast of Japan are examined using a simple layered model with a localized diapycnal transport due to the strong tidal mixing around the Kuril Islands. The modeled southernmost ...

Abstract: Hydrographic data from the World Ocean Database 2001 and Argo profiling floats were analyzed to study temperature inversions in the subarctic North Pacific Ocean. The frequency distribution of temperature inversions ...

Abstract: Vertical profile data of temperature and salinity from various sources were analyzed together with satellite altimeter data to investigate the water mass characteristics of warm and cold anticyclonic eddies in the western ...

Abstract: A simple two-layered in/outflow model is studied to explain the peculiarity of the Kuroshio path. The geometry south of Japan with a length scale L and the characteristic velocity U of the Kuroshio give an important parameter ...

Abstract: High-resolution hydrographic observations were conducted in September 2002 to describe the detailed structure of frontal waves along the Kuroshio Extension. Frontal waves were observed both in the upper and intermediate ...
