Diabatic Transformations along the Global Routes of the Middepth Meridional Overturning Circulation
(American Meteorological Society, 2022)The diabatic transformations of the middepth meridional overturning circulation (MOC) as it exits and reenters the South Atlantic to close the AMOC are studied using a state estimate assimilating data into a dynamically ... -
Influence of Wind on Subtidal Salt Intrusion and Stratification in Well-Mixed and Partially Stratified Estuaries
(American Meteorological Society, 2022)An idealized width-averaged model is employed to study the influence of wind stress on subtidal salt intrusion and stratification in well-mixed and partially stratified estuaries. We show that even in mild conditions, wind ... -
Baroclinic Tidal Cusps from Satellite Altimetry
(American Meteorological Society, 2022)The spatially averaged frequency spectrum of sea level has been computed at 4 cycle-per-year resolution and a Nyquist frequency of 0.5 cycles per hour using dual-satellite crossover data from the Jason and -
A Numerical Study on the Role of Mesoscale Cold-Core Eddies in Modulating the Upper-Ocean Responses to Typhoon Trami (2018)
(American Meteorological Society, 2022)With two groups of numerical experiments with and without the cold-core eddy (CCE), the impacts of the CCE on the upper-ocean responses to Typhoon Trami (2018) were investigated using a coupled atmosphere–ocean model. It ... -
Multidecadal Fluctuations of SST and Euphotic Zone Temperature off Northwest Africa
(American Meteorological Society, 2022)The Atlantic multidecadal variability (AMV) switched from a cool to a warm phase in 1995 and the mean euphotic zone (EZT) and sea surface temperature (SST) shifted upward by 0.57° and 0.69°C, respectively, between 1982–91 ... -
Coupling between Abyssal Boundary Layers and the Interior Ocean in the Absence of Along-Slope Variations
(American Meteorological Society, 2022)To close the overturning circulation, dense bottom water must upwell via turbulent mixing. Recent studies have identified thin bottom boundary layers (BLs) as locations of intense upwelling, yet it remains unclear how they ... -
Satellite Estimates of Mode-1 M2 Internal Tides Using Nonrepeat Altimetry Missions
(American Meteorological Society, 2022)Previous satellite estimates of internal tides are usually based on 25 years of sea surface height (SSH) data from 1993 to 2017 measured by exact-repeat (ER) altimetry missions. In this study, new satellite estimates of ... -
Vertical Motions Driven by Geostrophic Stress in Surface Boundary Layer under a Finite Ekman Number Regime
(American Meteorological Society, 2022)Geostrophic stress caused by a strong horizontal density gradient embedded in the surface boundary layer plays an important role in generating vertical motion and associated tracer transport. However, dependence of this ... -
Seasonal and Year-To-Year Variability of Boundary Currents and Eddy Salt Flux along the Eastern and Southern Coasts of Sri Lanka Observed by PIES and Satellite Measurements
(American Meteorological Society, 2022)Boundary currents along the Sri Lankan eastern and southern coasts serve as a pathway for salt exchange between the Bay of Bengal and the Arabian Sea basins in the northern Indian Ocean, which are characterized by their ... -
Moored Observations of the Currents and Transports of the Maluku Sea
(American Meteorological Society, 2022)The mean circulation and volume budgets in the upper 1200 m of the Maluku Sea are studied using multiyear current meter measurements of four moorings in the Maluku Channel and of one synchronous mooring in the Lifamatola ... -
Surface Quasigeostrophic Turbulence in Variable Stratification
(American Meteorological Society, 2022)Numerical and observational evidence indicates that, in regions where mixed layer instability is active, the surface geostrophic velocity is largely induced by surface buoyancy anomalies. Yet, in these regions, the observed ... -
The Dynamics of a Barotropic Current Impinging on an Ice Front
(American Meteorological Society, 2022)The vertical front of ice shelves represents a topographic barrier for barotropic currents that transport a considerable amount of heat toward the ice shelves. The blocking effect of the ice front on barotropic currents ... -
Headland Rip Very Low Frequency Fluctuations and Surfzone Eddies During High-Energy Wave Events
(American Meteorological Society, 2022)A wave-group-resolving model is used to investigate the driving mechanisms and the spatiotemporal variability of very low frequency (VLF) fluctuations of a headland deflection rip, measured during a 4-m oblique wave event. ... -
Interannual and Seasonal Along-Shelf Current Variability and Dynamics: Seventeen Years of Observations from the Southern New England Inner Shelf
(American Meteorological Society, 2022)The characteristics and dynamics of depth-average along-shelf currents at monthly and longer time scales are examined using 17 years of observations from the Martha’s Vineyard Coastal Observatory on the southern New England ... -
Turbulent Thermal-Wind-Driven Coastal Upwelling: Current Observations and Dynamics
(American Meteorological Society, 2022)A remarkably consistent Lagrangian upwelling circulation at monthly and longer time scales is observed in a 17-yr time series of current profiles in 12 m of water on the southern New England inner shelf. The upwelling ... -
Mixing Driven by Critical Reflection of Near-Inertial Waves over the Texas–Louisiana Shelf
(American Meteorological Society, 2022)Studies of internal wave-driven mixing in the coastal ocean have been focused on internal tides, while wind-driven near-inertial waves (NIWs) have received less attention in this regard. This study demonstrates a scenario ... -
A Forward Energy Flux at Submesoscales Driven by Frontogenesis
(American Meteorological Society, 2022)Submesoscale currents, comprising fronts and mixed-layer eddies, exhibit a dual cascade of kinetic energy: a forward cascade to dissipation scales at fronts and an inverse cascade from mixed-layer eddies to mesoscale eddies. ... -
Observation of Bottom-Trapped Topographic Rossby Waves to the West of the Luzon Strait, South China Sea
(American Meteorological Society, 2022)Topographic Rossby waves (TRWs) play an important role in deep-ocean dynamics and abyssal intraseasonal variations. Observational records from 15 current- and pressure-recording inverted echo sounders (CPIESs) and two ... -
Hurricane Sally (2020) Shifts the Ocean Thermal Structure across the Inner Core during Rapid Intensification over the Shelf
(American Meteorological Society, 2022)Prediction of rapid intensification in tropical cyclones prior to landfall is a major societal issue. While air–sea interactions are clearly linked to storm intensity, the connections between the underlying thermal conditions ... -
Passive Acoustic Determination of Spectral Wave Breaking Dissipation
(American Meteorological Society, 2022)When a wave breaks, it produces bubbles whose sizes depend on the breaking severity. This paper attempts to estimate wave breaking dissipation through a passive acoustic method. Initially, regular waves were forced to break ...
