RISA Shift in Western Tropical Pacific Sea Level Trends during the 1990s
Publisher: American Meteorological Society
Abstract: acific Ocean sea surface height trends from satellite altimeter observations for 1993?2009 are examined in the context of longer tide gauge records and wind stress patterns. The dominant regional trends are high rates in ...
Boundary Mixing Associated with Tidal and Near-Inertial Internal Waves
Publisher: American Meteorological Society
Abstract: Moorings deployed on the south (August?November 2002) and north (November 2002?June 2003) flanks of the Kaena Ridge, Hawaii, are used to document the flow variability associated with mixing within 200 m from the boundary, ...
The Scattering of Long Coastal-Trapped Waves in Frictional Seas
Publisher: American Meteorological Society
Abstract: The scattering of coastal-trapped waves (CTWs) by a region of irregular shelf bathymetry is determined from a circulation integral of the depth-integrated momentum equations. For relatively weak stratification the conservation ...
Interannual Geostrophic Current Anomalies in the Near-Equatorial Western Pacific
Publisher: American Meteorological Society
Abstract: A network of island tide gauges is used to estimate interannual geostrophic current anomalies (GCAs) in the western Pacific from 1975 to 1997. The focus of this study is the zonal component of the current averaged between ...
Characterization of Dry Conditions across the U.S.-Affiliated Pacific Islands during Near-Neutral ENSO Phases
Publisher: American Meteorological Society
Abstract: AbstractThe U.S.-Affiliated Pacific Islands (USAPIs), located in the tropical western Pacific, are very susceptible to severe drought. Dry season (December?May) rainfall anomalies have different relationships to ENSO for ...
Flow and Mixing around a Small Seamount on Kaena Ridge, Hawaii
Publisher: American Meteorological Society
Abstract: Microstructure observations over a small seamount on the Kaena Ridge, Hawaii, showed asymmetry in the along- and across-ridge directions. The ?400-m-high seamount is on the southern edge of the ridge (centered at 21°43?49?N, ...
Structure, Propagation, and Mixing of Energetic Baroclinic Tides in Mamala Bay, Oahu, Hawaii
Publisher: American Meteorological Society
Abstract: Large semidiurnal vertical displacements (≈100 m) and strong baroclinic currents (≈0.5 m s?1; several times as large as barotropic currents) dominate motions in Mamala Bay, outside the mouth of Pearl Harbor, Hawaii. During ...
Tidal Mixing Events on the Deep Flanks of Kaena Ridge, Hawaii
Publisher: American Meteorological Society
Abstract: A 3-month mooring deployment (August?November 2002) was made in 2425-m depth, on the south flank of Kaena Ridge, Hawaii, to examine tidal variations within 200 m of the steeply sloping bottom. Horizontal currents and ...

Wind-Driven Coastal Sea Level Variability in the Northeast Pacific
Publisher: American Meteorological Society
Abstract: he rate of coastal sea level change in the northeast Pacific (NEP) has decreased in recent decades. The relative contributions to the decreased rate from remote equatorial wind stress, local longshore wind stress, and local ...
