On the interaction between the nonlinear internal waves and the Pearl River plume.

ABSTRACT: In late July of 2016, a temperature mooring deployed north of Dongsha Atoll has recorded the enhancement of nonlinear internal waves (NIWs) associated with regionally environmental variability. Observations revealed large daily temperature fluctuations of 10-14 °C at depths of 80-100 m, with peak variations occurring after spring tides and showing an increasing trend, indicative of intensified NIW activity. This study investigates the uncertainties regarding the influence of river flux, precipitation, and other environmental factors on the short-term intensification of NIWs. Through the analysis of multiple independent oceanic and atmospheric datasets, we identified significant variations in zonal oceanic currents and the advection of low-salinity water discharged from the Pearl River to t
