STUDY OF INTERNAL TIDE CHARACTERISTICS IN THE EASTERN ARABIAN SEA USING OBSERVATIONS AND NUMERICAL MODELS

Local dissipation ratio of internal tides at key topographic features in the South China Sea

The local dissipation ratio of internal tides,  q * , is a critical parameter in tidal mixing parameterizations. However, the conventionally adopted constant value of 0.3 in large-scale ocean models neglects its significant spatiotemporal variability. Based on the MITgcm LLC4320 simulation, the internal tidal ener...

Monsoonal Wind‐Driven Ocean Dynamics Drive Seasonal Sea Surface Temperature Variability in the Indonesian Seas

The governing mechanisms of sea surface temperature (SST) variability in the Indonesian seas, which exerts a significant influence on atmospheric convection and Indo‐Pacific climate, are investigated using observations and high‐resolution regional ocean model simulations. Observations show that SST variability is dom...

Numerical Modelling of the Barotropic Tides in the Gulf of Aden

The Gulf of Aden (GA) is a strategically dynamic water basin linking the Red Sea basin with the Arabian Sea via the Bab el Mandeb Strait. In spite of its importance for oil transportation globally and regional hydrodynamics, tidal propagation remains relatively understudied. Thus, in this study, a depth-averaged 2D bar...

Spatiotemporal characteristics of marine heatwaves driven by different factors in the South China Sea

Observed Bottom Intensified Diurnal Currents on the Upper Continental Slope North of Svalbard

In the Arctic Ocean, dissipation is generally weak except for some hot spots on the continental slope or along the edge of the Yermak Plateau where observations suggest that tidal currents are the main source of dissipation. In this study, we analyze observations collected between September 2017 and November 2019 f...

Multi‐year subsurface mixing properties and air–sea interaction in the Arabian Sea Warm Pool

Due to social and economic impacts on India and the surrounding countries, the Indian Summer Monsoon (ISM) has been at the forefront of a rich history of scientific discovery embedded in a broader scientific objective to understand the air–sea coupling, dynamics, and thermodynamics of the Indian Ocean. The Arabian Se...
