A mooring system and two sites of bottom currents were deployed over the slope near shelf break on propagating paths internal solitary waves (ISWs), west off Dongsha Atoll in northern South China Sea. Data indicated that energetic ISWs obliquely shoaled onto an approximately 290° direction, causing strong reversing (some exceeding 80 cm/s) bottom. Two types sandwaves short scour channels are discernible seafloor break, which have reasonable correlations with incident tides. Type 1 sandwaves,...
Abstract Bottom current at the equatorial gap of Ninety East Ridge is revealed by long‐term bottom mooring observations from 24 December 2019 to 2 April 2021. It found that observed has significant intraseasonal variability (ISV) with a dominant time scale ∼33 days, which becomes enhanced in boreal summer and winter. Variability was explored using Mercator Ocean outputs, enhancement ISV closely related westward propagation Rossby waves originating eastern boundary, their ray paths vertically...
The impacts of mesoscale eddies on the modulation typhoon-induced oceanic responses are important for understanding ocean dynamics. Satellite observations identified prominent surface temperature and chlorophyll changes over regions with after two sequential typhoons, e.g., Linfa Nangka, in South China Sea. typhoons were more within cyclonic than anticyclonic eddies. wind speed (translation speed) was much larger (slower) that Nangka; thus, induced by stronger. However, second typhoon easily...
Internal tides are pivotal dynamic processes enhancing the mixing of oceanic waters and facilitating energy transfer across various scales within ocean. In recent years, proliferation satellite altimetry observations has enabled global predictions elevation phase internal tides. This study, leveraging advanced tide prediction model known as Multivariate Inversion Ocean Surface Topography-Internal Tide Model (MIOST-IT), employs a two-dimensional Fourier bandpass filtering approach to...
A mooring and a real-time buoy allowed observation of oceanic atmospheric variation in the wake 2008 Typhoon Hagupit South China Sea (SCS). In present study, regional ocean modeling system (ROMS) was used to explore propagation characteristics near-inertial waves (NIWs) along continental shelf. The simulated NIWs were similar results. There strong after passage Hagupit, presented dual peaks, with one located mixed layer other at thermocline. upper layer, kinetic energy on left typhoon track...
The quasi-biweekly oscillation (QBWO) is the second most dominant intraseasonal mode for circulation over Northwestern Pacific (WNP) during boreal summer. In this study, we investigated how QBWO modulates tropical cyclone (TC) activities WNP from dynamic and thermodynamic perspectives. propagation of can be divided into four phases through empirical orthogonal function analysis vorticity at 850 hPa, which was proven to effective in extracting signal. TC generation landings are significantly...
Abstract The southern Bay of Bengal (BoB) is a region rich mesoscale eddy activity that plays an important role in modulating water exchange between the BoB and Arabian Sea. Although statistical surface characteristics eddies have been sufficiently explored previously, most studies concentrated on western central BoB, but rarely BoB. In this study, energetic anticyclonic (AE) was detected by long‐term mooring observations during June 2020. revealed AE‐induced maximum temperature salinity...
The northern Andaman Sea (AS) continental shelf is unique due to the diverse marine ecosystem and existences of both hypoxia internal tides, but limited in situ observations restrict our understanding hydrographic dynamic process. Based on turbidity, mean volumes backscattering strength (MVBS), we qualitatively studied distribution characteristics temporal variation suspended matters AS their relation tides. results MVBS turbidity revealed that exhibited a three-layer vertical structure....
Near-inertial waves (NIWs) play an important role in determining oceanic energy and are highly related to dynamics, including tropical cyclones (TCs). However, most studies have focused on the features of NIWs upper layer, characteristics near seabed remain poorly understood. Based current meter records from two moorings, we examined during passage four TCs, namely, Fengshen, Kammuri, Nuri Hagupit, northern South China Sea (SCS). The moorings were deployed continental slope, with one located...
