Short summary
The high dense AUVs’ dataset in SCS provides 24498 temperature and salinity profiles and covers 463 days’ experiments, including 83 AUGs’ and 2 AUVs’ experiments. To our knowledge, the resolution and length of this dataset is enough in detecting the asymmetry, vertical tilt, temporal evolution of MEs, and the submesoscale processes. The dataset is expected to improve the accuracy of current and biogeochemistry numerical model. More projects gathering AUVs network will be promoted in future.

Observational gridded products are essential for understanding the ocean, the atmosphere, and climate change; they support policy decisions and socioeconomic developments. This study provides an update of an ocean subsurface temperature and ocean heat content gridded product, named the IAPv4 data product, which is available for the upper 6000 m (119 levels) since 1940 (more reliable after ~1955) for monthly and 1° × 1° temporal and spatial resolutions.

In this work, successive air–sea heat flux-related data were acquired over the course of a year (01/02/2016–31/01/2017) at the YXASFT on Yongxing Island. Then, seasonal comparisons were conducted for the daily mean surface bulk variables and heat fluxes between the WHOI OAFlux products and YXASFT observations. The conclusions in this paper will provide useful reference for researchers on how to select the appropriate OAFlux datasets in different seasons over the South China Sea.

We present a continuous in situ hydro-meteorology observational dataset from a set of instruments first deployed in December 2012 in the south of Sri Lanka, facing toward the north Indian Ocean. This study describes the survey, deployment, and measurements of wind and wave, with the aim of offering future users of the dataset the most comprehensive and as much information as possible.

Seasonal changes of the mixed layer heat storage in the BoB significantly contribute to the regional weather and climate by inducing air-sea interactions. Seasonality associated with vertical mixing and barrier layer indicates the seasonal response from the ocean in the BoB. This study will provide a significant contribution to further studies on air-sea interactions in the BoB, especially the role of vertical mixing and barrier layer variation during cyclone formation and intensification.

we applied EnOI assimilation method with a global ocean model (MOM4.0) to estimate three-dimensional global ocean states when assimilating various variables, e.g., SST, SSH, SSS, and T/S profiles, in an idealized twin-experiment framework. The ocean surface currents in the tropics were better predicted when initial conditions produced by assimilating T/S profiles, while surface data assimilation became more important at higher latitudes, particularly near the western boundary currents.

South China Sea is a hardest-hit area of typhoon, and there are server typhoons in Beibu Bay. Satellite data and ocean model are effective method now. But this will need lots of social resources. Our method is a feasible and economical method. Now lots of hydrological stations have long surge data in china. According to these history data, we can get an extreme surge relationship between two or more stations. Combining front stations data and the relationship, we can make advanced prediction.

Short summary
We examine near-inertial variability of the meridional overturning circulation in the South China Sea (SCSMOC) using a global 1 / 12° ocean reanalysis. Based on wavelet analysis and power spectrum, we suggest that deep SCSMOC has a significant near-inertial band. The maximum amplitude of the near-inertial signal in the SCSMOC is nearly 4 Sv. The spatial structure of the signal features regularly alternating counterclockwise and clockwise overturning cells.
We examine near-inertial variability of the meridional overturning circulation in the South...
