Variability of Heat Content and Eddy Kinetic Energy in the Southeast Indian Ocean: Roles of the Indonesian Throughflow and Local Wind Forcing
(American Meteorological Society, 2022)Prominent interannual-to-decadal variations were observed in both heat content and mesoscale eddy activity in the southeast Indian Ocean (SEIO) during 1993–2020. The 2000–01 and 2008–14 periods stand out with increased ... -
Identification of Thermohaline Sheet and Its Spatial Structure in the Canada Basin
(American Meteorological Society, 2022)Thirty-four individual thermohaline sheets are identified at depths of 170–400 m in the Canada Basin of the Arctic Ocean by using the hydrographical data measured with the Ice-Tethered Profilers (ITPs) between August 2005 ... -
Mixing Pathways in Simple Box Models
(American Meteorological Society, 2022)Tracer variance budgets can be used to estimate bulk mixing in a control volume. For example, simple, analytical, bulk formulations of salt mixing, defined here as the destruction of salinity variance, can be found for ... -
Energy Spectra and Vorticity Dynamics in a Two-Layer Shallow Water Ocean Model
(American Meteorological Society, 2022)The dynamically adaptive WAVETRISK-OCEAN global model is used to solve one- and two-layer shallow water ocean models of wind-driven western boundary current (WBC) turbulence. When the submesoscale is resolved, both the ... -
Instability of a Surface Jet over Rough Topography
(American Meteorological Society, 2022)The instability of a surface-trapped jet over rough bottom topography is examined using a linearized quasigeostrophic model. The jet is laterally sheared and thus susceptible to both barotropic and baroclinic instability. ... -
Rogue Waves in the Southern North Sea—The Role of Modulational Instability
(American Meteorological Society, 2022)The role of the modulational instability for rogue wave generation in the ocean is still under debate. We investigated a continuous dataset, consisting of buoy and radar wave elevation data of different frequency resolutions, ... -
Near-Inertial Wave Interactions and Turbulence Production in a Kuroshio Anticyclonic Eddy
(American Meteorological Society, 2022)Interactions between near-inertial waves and the balanced eddy field modulate the intensity and location of turbulent dissipation and mixing. Two EM-APEX profiling floats measured near-inertial waves generated by Typhoons ... -
Winter–Summer Transition in the Southern South China Sea Western Boundary Current
(American Meteorological Society, 2022)The winter–summer transition in the southern South China Sea (SCS) western boundary current (WBC) is studied. Two categories have been identified. In case 1, the southern SCS WBC transition in the lower layer (below the ... -
Diabatic Upwelling in the Tropical Pacific: Seasonal and Subseasonal Variability
(American Meteorological Society, 2022)The equatorial Pacific zonal circulation is composed of westward surface currents, the eastward equatorial undercurrent (EUC) along the thermocline, and upwelling in the eastern cold tongue. Part of this upwelling arises ... -
Meddies and Their Sea Surface Expressions: Observations and Theory
(American Meteorological Society, 2022)The sea surface expressions of Mediterranean Water eddies, known as “meddies,” are observed in satellite data, and their main characteristics are measured. Satellite altimeter observations of surface expressions are detected ... -
Low-Frequency Dynamic Ocean Response to Barometric-Pressure Loading
(American Meteorological Society, 2022)Changes in dynamic manometric sea level -
Regimes and Transitions in the Basal Melting of Antarctic Ice Shelves
(American Meteorological Society, 2022)The Antarctic Ice Sheet is losing mass as a result of increased ocean-driven melting of its fringing ice shelves. Efforts to represent the effects of basal melting in sea level projections are undermined by poor understanding ... -
Impact of El Niño–Southern Oscillation on the Benguela Upwelling
(American Meteorological Society, 2022)The impact of El Niño–Southern Oscillation (ENSO) on the southern African climate is well documented and provides skill in the seasonal forecast of rainfall, but less is known about the impact of ENSO on the Benguela Current ... -
Quantifying Cross-Shelf Transport in the East Australian Current System: A Budget-Based Approach
(American Meteorological Society, 2022)Cross-shelf transport plays an important role in the heat, salt, and nutrient budgets of the continental shelf. In this study, we quantify cross-shelf volume transport and explore its dynamics within a high-resolution ... -
Large-Amplitude Internal Wave Transformation into Shallow Water
(American Meteorological Society, 2022)Large-amplitude internal solitary wave (ISW) shoaling, breaking, and run-up was tracked continuously by a dense and rapidly sampling array spanning depths from 500 m to shore near Dongsha Atoll in the South China Sea. ... -
A Deep Learning Model for Improved Wind and Consequent Wave Forecasts
(American Meteorological Society, 2022)The paper presents a combined numerical–deep learning (DL) approach for improving wind and wave forecasting. First, a DL model is trained to improve wind velocity forecasts by using past reanalysis data. The improved wind ... -
Langmuir Circulations Transfer Kinetic Energy from Submesoscales and Larger Scales to Dissipative Scales
(American Meteorological Society, 2022)Surface gravity wave effects on currents (WEC) cause the emergence of Langmuir cells (LCs) in a suite of high horizontal resolution (Δ -
The Vertical Middepth Ocean Density Profile: An Interplay between Southern Ocean Dynamics and Interior Vertical Diffusivity
(American Meteorological Society, 2022)The middepth ocean temperature profile was found by Munk in 1966 to agree with an exponential profile and shown to be consistent with a vertical advective–diffusive balance. However, tracer release experiments show that ... -
Estimating the Ocean Interior from Satellite Observations in the Kerguelen Area (Southern Ocean): A Combined Investigation Using High-Resolution CTD Data from Animal-Borne Instruments
(American Meteorological Society, 2022)Observational surface data are utilized to reconstruct the subsurface density and geostrophic velocity fields via the “interior + surface quasigeostrophic” (isQG) method in a subdomain of the Antarctic Circumpolar Current ... -
Sources and Pathways of Intraseasonal Meridional Kinetic Energy in the Equatorial Atlantic Ocean
(American Meteorological Society, 2022)In the equatorial Atlantic Ocean, meridional velocity variability exhibits a pronounced peak on intraseasonal time scales whereas zonal velocity dominantly varies on seasonal to interannual time scales. We focus on the ...
