Abstract Historical trends in the direction and magnitude of ocean surface wave height, period, or are debated due to diverse data, time-periods, methodologies. Using a consistent community-driven ensemble global products, we quantify establish regions with robust multivariate fields between 1980 2014. We find that about 30–40% experienced seasonal mean extreme direction. Most Southern Hemisphere exhibited strong upward-trending heights (1–2 cm per year) periods during winter summer. Ocean...
There are numerous global ocean wave reanalysis and hindcast products currently being distributed used across different scientific fields. However, there is not a consistent dataset that can sample all existing based on standardized framework. Here, we present describe the first coordinated multi-product ensemble of present-day fields available to date. This dataset, produced through Coordinated Ocean Wave Climate Project (COWCLIP) phase 2, includes general extreme statistics significant...
For the first time, directional wave spectra are reconstructed from visually observed wind data over North Atlantic Ocean. this purpose, a novel analytical approach for calculating spreading function visual ship-based observations is proposed. Natively and inherently separated estimates of sea swell heights, periods, directions propagation provide independent functions systems in given area time. Shape parameter mean angle evaluated spatially temporally averaged sine cosine projections...
Abstract Four global wind wave hindcasts based on the third‐generation spectral model WAVEWATCH III forced by ERA5, ERA‐Interim, National Centers of Environmental Prediction and Climate Forecast System Reanalysis (CFSR) MERRA2 reanalyzes for 1980–2019 are presented. Absolute magnitudes both 10‐m speeds significant heights largest in CFSR CFSR‐based hindcast respectively, particularly extratropical regions. The differences annual extremes between ERA5 (and corresponding hindcasts) amount to...
Abstract Four global wind wave hindcasts based on ERA5, MERRA2, ERA-I and CFSR reanalyses spectral model WAVEWATCH III for the period from 1980 to 2017 have been validated against satellite altimetry NDBC buoys 1 year. Hindcast newly released ECMWF reanalysis ERA5 demonstrated best agreement with both altimetery (with normalized bias being up 5%, RMSE 0.5 m) buoy measurements, including values of upper percentiles. In general, all show good correspondence observational data thus can be used...
Abstract. Wind waves play an important role in the climate system, modulating energy exchange between ocean and atmosphere effecting mixing. However, existing ship-based observational networks of wind are still sparse, limiting therefore possibilities validating satellite missions model simulations. In this paper we present data collected on three research cruises North Atlantic Arctic 2020 2021 SeaVision system for measuring wave characteristics over open with a standard marine navigation...
Validation of the global model long-term wind wave hindcasts against observations from Voluntary Observing Ships (VOS) are a high demand, as VOS provide separate estimates sea and swell for long period about several decades. However, data suffer spatial temporal inhomogeneity sampling direct comparisons with output difficult there is no way quantifying differences associated setting uncertainties. In this study, we perform validation 40-yr (1980-2019) hindcast performed WAVEWATCH-III...
For decades, satellite altimetry is providing reliable data on the sea level, surface currents, tides, planetary and wind waves ice. We propose a potential enhancement of collecting special subsets for better temporal spatial sampling dynamics Sub-Polar seas. show that peculiarities orbits TOPEX/Poseidon Jasons’ missions generate regular grid crossovers which locations are fixed in space time orbit cycles. Two types these specified: self-crossovers (SC) occurring as intersections tracks same...
Satellite altimetry is successfully developing during the past three decades for sea level, ocean dynamics, coastal oceanography, planetary waves, tides, wind and wave, ice cover, Earth’s gravity field, climatology research. We propose a new essential add-on of satellite related to peculiarities orbits Topex/Poseidon Jasons’ missions which were not mentioned before in scientific publications. Derived subsets “self-crossover” “inter-crossover” points sub-polar latitudes are discussed detail...
Atmospheric climatological characteristics of the Barents Sea were analyzed in model output AMIP5 models for present climate and projections under RCP4.5 RCP8.5 scenarios different periods 21st century. The results reveal strong changes mean surface air temperature amounting to more than 2 degrees during In line with this frequency duration heat waves is increasing number cold decreasing course time period analyzed. Mean wind speed demonstrates upward both these are accompanied by change...
