The interferometric imaging radar altimeter (InIRA) aboard the Chinese Tiangong-2 space laboratory is first spaceborne working at low incidence angles. This study focuses on retrieval of significant wave heights (SWHs) from InIRA data. retrieved SWHs can be used for correcting sea state bias InIRA-derived surface and supplement SWH products other sensors. First, we analyzed tilt, range bunching...

The impact of the high space-temporal variability wind field during moderate and intense storm stages a tropical cyclone on wave as computed by numerical model WaveWatch III is investigated in this work. realistic fields are generated high-resolution implementation HWRF Gulf Mexico stored over 15 min intervals. spatial structure highly variable space time, although its mean very similar to that...

Against the background of global climate change, warming water temperature Antarctic surface (<500 m) is worthy study. Therefore, purpose this study was to investigate short-term variations in from January 2000 December 2016, using offline coupled ocean models, i.e., WAVEWATCH-III (WW3) model and Stony Brook Parallel Ocean Model (sbPOM). The validation WW3-simulated significant wave height (...

Climate change can give rise to significant changes in the intensity and frequency of extreme events. In present study, wave events off central-eastern coast Red Sea, near city Jeddah, were investigated using a 39-year hindcast generated WaveWatch III configured at 3.3 km resolution forced with ERA5 reanalysis winds. The validated model outputs used derive annual seasonal climatology for region...

Abstract Accurately simulating the interactions between components of a coupled Earth modelling system (atmosphere, sea-ice, and wave) on kilometer-scale resolution is new challenge in operational numerical weather prediction. It difficult due to complexity interactive mechanisms, limited accuracy model scarcity observations available for assessing relevant processes. This study presents newly ...

Extreme sea waves, although rare, can be notably dangerous when associated with energetic states and generate risks for the navigation. In last few years, they have been object of extensive research from scientific community that helped understanding main physical aspects; however, estimate extreme waves probability in operational forecasts is still debated. this study, we analyzed a number sea...

Coastal flooding is one of the serious problems facing most coastal areas in world. On January 17 and December 7, 2021, hit area Manado, North Sulawesi, Indonesia. The disaster disrupted economic activities on coast Manado Bay. This study analyzed dynamics atmosphere sea during flood events using water level data from Geospatial Information Agency, which was then filtered to separate residual a...

Abstract A high-resolution third-generation wave model based on unstructured grids, WAVEWATCH III (WW3), was used to study the projected future climate of Bass Strait and south-east Australia under two different greenhouse gas emission scenarios (SSP1-2.6 SSP5-8.5). The model, forced with winds from Australian ACCESS-CM2 Global Climate Model, shows good agreement coastal long-term buoy observat...

Synthetic Aperture Radar (SAR) in wave mode is a powerful tool for monitoring sea states terms of long-period ocean swells specific directional partition. Since 2016, SARs aboard Sentinel-1A/B operating have provided swell spectra dataset as Level-2 Ocean products on continuous and global basis over open oceans. Furthermore, Level-3 are processed by Copernicus Marine Environment Monitoring Serv...

The Doppler shift obtained from synthetic aperture radar (SAR) measurements comprises the combined contribution to radial motion of ocean surface induced by sea state (wind waves and swell) underlying currents. Hence, obtain reliable estimates current, sea-state-induced shifts must be accurately estimated eliminated. In this study, we use a semiempirical dual co-polarization velocity (DPDop) mo...
