A kilometre-scale coupled ocean–atmosphere simulation is used to study the impact of a medicane on the oceanic upper layer. The processes responsible for the surface cooling are comparable to those of weak tropical cyclones. The oceanic response is influenced by the dynamics of the central Mediterranean. In particular, a cyclonic eddy leads to weaker cooling. Heavy rain occuring early in the event creates a salinity barrier layer, reinforcing the effects of the surface fluxes on the cooling.

On ice-affected coasts, obtaining year-long sea level records for traditional tidal predictions is difficult. We evaluate the complete tidal species modulation with tidal constant corrections (CTSM+TCC) method for predicting tides at the "mixed, mainly diurnal" Jang Bogo Antarctic Research Station in the Ross Sea, Antarctica, using short in situ records plus longer records from the nearby "diurnal" Cape Roberts. The method succeeded in using data from periods with above-average tidal ranges.

Based on a well-validated ocean circulation model, we found that near-inertial oscillations (NIOs) and near-inertial kinetic energy (KEni) varied distinctly during forcing and relaxation stages of tropical cyclone (TC) forcing, and the horizontal and vertical transport of KEni was largely modulated by the velocity and vorticity of the jet in the semi-enclosed South China Sea (SCS). This study enriches our understanding of the spatial–temporal variability of NIOs in the frequently TC-affected SCS.
