Abstract A severe coral bleaching event occurred in the Beibu Gulf during boreal summer 2020. This was caused by record-breaking warm sea surface temperature (SST) anomalies northern South China Sea (NSCS). Anomalous anticyclones (AACs) over NSCS linked to Indian Ocean warming and La Niña induced extreme warming. In May–July 2020, anomalous anticyclonic-shear easterlies appeared tropical western Pacific as a Kelvin wave response These resulted an AAC northwestern via Ekman dynamics. Besides,...

In the northern Bay of Bengal, mechanisms seasonal sea-level variation have not previously been examined, and understanding longer-term inter-annual is also concrete. These parameters are addressed in this study utilizing available tide gauge satellite altimetry data. The contribution steric sea level to variations quantified, statistical analysis performed determine correlations various atmospheric oceanic factors with level. This suggests that trend rise bay (4 ± 1.33 mm/year) higher than...

Abstract. Numerical simulations of ocean surface waves along the Australian coasts are performed with spectral wave model WAVEWATCH III (WW3) and state-of-the-art physics numerics. A large-scale, high-resolution (1–15 km) unstructured mesh is designed for better resolving extensive coastline. Based on verification against altimeter buoy observations, it found that WW3 simulations, observation-based source term package (i.e., ST6) other relevant physical processes, perform reasonably well in...

In the Northwest Pacific (NWP), where a unique monsoon climate exists and both typhoons extratropical storms occur frequently, hazardous waves pose significant risk to maritime safety. To analyze 20-year variability of in this region, study utilized hourly reanalysis data from ECMWF ERA5 dataset covering period 2001–2020, alongside wave assessment method. The exhibits better consistency, temporal spatial dimensions, than satellite data. Although wind seas more frequently swells, swells make...

A three‐dimensional wave‐current coupled modeling system is used to examine the influence of waves on coastal currents and sea level. This consists wave model‐WAM (Cycle 4) Princeton Ocean Model (POM). The results from this study show that it important incorporate surface effects into storm surge circulation models. Specifically, we find (1) models without generally under estimate not only peak but also water level drop which can cause substantial impact environment, (2) introducing...
