Partitioning is a process used to separate wind-sea and swell contributions in an ocean wave directional spectrum simplify, hence make more useful, the interpretation of for users data. HF radar systems can measure over regions coastal from coast 100 km offshore with good spatial temporal resolution depending on operating frequency bandwidth. Such hundreds spectra across field view radar, so th...

Significant wave height (SWH) in shallow waters is assessed by generating two hindcasts; the first uses ERA-Interim wind fields and second one from ERA5 to quantify improvement of surface winds on SWH representativeness, both deep along Chilean coastline. Additionally, field predictions Global Forecast System (GFS) were used assess representativeness waters. Oceanographic buoys validate waters,...

Over recent decades, the Arctic Ocean has experienced dramatic variations due to climate change. By retreating at a rate of 13% per decade, sea ice opened up significant areas ocean, enabling wind blow over larger fetches and potentially enhancing wave climate. Considering intense seasonality rapid changes Ocean, non-stationary approach is applied time-varying statistical properties investigate...

Climate change impacts threaten coastal areas all over the world, driven by increasing extreme sea levels. With higher surface and air temperatures, continued sealevel rise high exposure vulnerability of about 20 million people living in low-lying areas, climate affects Mediterranean Sea significantly more than world average is therefore defined as a hotspot (Ali, 2022). Projected changes waves...

The wind and wave derived from the scatterometer altimeter on board Chinese Haiyang-2B (HY-2B) satellite were systemically evaluated in this study. analysis of matchups between Advanced Scatterometer (ASCAT) winds HY-2B with speeds up to 25 m/s showed a 0.78 Root-Mean-Square Error (RMSE) 0.97 Correlation (COR), superior 1.2 RMSE 0.93 COR HY-2B. Simultaneously, significant heights (SWH) measured...

This study unravels 58-years (1961–2018) of wind-waves in the Mediterranean Sea (MS). A wave dataset was developed using model WAVEWATCH III forced with high-resolution (5.5 km) UERRA-MESCAN-SURFEX downscaled wind fields which better contain imprint local geomorphology compared to other, coarser datasets used previous studies. Thus, improving reliability and characterization wind-wave climate b...

Accurate wind-wave forecasting in enclosed and semi-enclosed basins is a challenging task, demanding primarily for high-resolution wind forcing at regional scale. This generally obtained with dynamical downscaling from low-to-mid resolution atmospheric model. In this context, new wave system the marginal Adriatic Sea herein presented aimed proposing an alternative strategy accurate (semi-) that...

The main parameters of wind waves in the World Ocean are connected with global climate change. Renewable energy technologies, intensive shipping, fishery, marine infrastructure, and many different human activities coastal zone open sea need knowledge about wind-wave climate. motivation this research is to share various wave high spatial resolution via a modern cartographic web atlas. developed ...
