This study presents simulations of the global ocean wave climate corresponding to surface winds and sea ice concentrations as simulated by five CMIP5 (Coupled Model Intercomparison Project Phase 5) models for historical (1979–2005) RCP8.5 scenario future (2081–2100) periods. To tackle numerical complexities associated with inclusion North Pole, WAVEWATCH III (WW3) model was used a customized unstructured Spherical Multi-Cell grid ∼100 km offshore ∼50 along coastlines. The wind data, WW3 were...
Abstract The Arctic Ocean wave climate is undergoing a dramatic change due to the sea ice retreat. This study presents simulations of regional corresponding surface winds and concentrations as simulated by five CMIP5 (Coupled Model Intercomparison Project Phase 5) models for historical (1975–2005) RCP8.5 scenario future (2081–2100) periods. annual maximum significant height projected increase up 6 m offshore two three times greater than 1979–2005 value along some coastlines, waves become...
Abstract This dataset, produced through the Coordinated Ocean Wave Climate Project (COWCLIP) phase 2, represents first coordinated multivariate ensemble of 21 st Century global wind-wave climate projections available (henceforth COWCLIP2.0). COWCLIP2.0 comprises general and extreme statistics significant wave height ( H S ), mean period T m direction θ ) computed over time-slices 1979–2004 2081–2100, at different frequency resolutions (monthly, seasonally annually). The full comprising 155...
Abstract. The co-occurrence of (not necessarily extreme) precipitation and surge can lead to extreme inland water levels in coastal areas. In a previous work the positive dependence between two meteorological drivers was demonstrated managed system Netherlands by empirically investigating an 800-year time series levels, which were simulated via physical-based hydrological model driven regional climate large ensemble. this study, we present impact-focused multivariate statistical framework...
Abstract Extreme surface ocean waves are often primary drivers of coastal flooding and erosion over various time scales. Hence, understanding future changes in extreme wave events owing to global warming is socio-economic environmental significance. However, our current knowledge potential high-frequency (defined here as having return periods less than 1 year) largely unknown, despite being strongly linked hazards across scales relevant management. Here, we present climate-modeling evidence,...
[1] Projected future regional wave climate scenarios at a high temporal-spatial scale were obtained for the NW Mediterranean Sea, using five combinations of regional-global circulation models. Changes in variables analyzed and related to variations forcing wind projections, while also evaluating evolution presence different types sea states. To assess significance changes produced, bootstrap-based method was proposed, which accounts autocorrelation data correctly reproduces extremes. For...
Coastal flood damage is primarily the result of extreme sea levels. Climate change expected to drive an increase in these extremes. While proper estimation changes storm surges essential estimate levels, there remains low confidence future trends surge contribution Alerting local populations imminent levels also critical protecting coastal populations. Both predicting and projecting require reliable numerical prediction systems. The SurgeMIP (surge model intercomparison) community has been...
The short‐term statistics of 10 million individual waves observed with buoys in deep water have been investigated, corrected for a sample‐rate bias, and normalized the standard deviation surface elevation (the range wave heights is 0 < 10). trough depths are found to be Rayleigh distributed near‐perfect scaling. crest also but 3% higher than given by conventional distribution. not well predicted distribution (overprediction 9.5% on average), they very Rayleigh‐like distributions obtained...
This study examines the main physical processes related to coastal and port engineering that could be altered by future changes in wave parameters as a consequence of climate change. To estimate order magnitude potential these processes, several assumptions simplifications are made and, most cases, they assessed using simple, empirical state-of-the-art expressions. The studied grouped three categories according whether affect beaches, harbors or structures general. estimated function...
Abstract The projected changes and trends in the regional annual monthly maxima of significant wave height ( H s ) Arctic Ocean are studied using simulations derived from CMIP5 (Coupled Model Intercomparison Project Phase 5) climate for 1979–2005 2081–2100 periods. Under RCP8.5 scenario, maximal increases on average up to ∼3 cm/year, or >0.5%/year, relative 1986–2005 climatological value, many areas (and 0.8%/year east side Ocean). While strong winds need occur large waves develop, wind...
<title>Abstract</title> In the next 25 years an unprecedented number of new marine artificial structures, over 75,000 offshore wind turbines alone, are planned to meet global net zero targets. Structures required last for multiple decades in hostile environment; where largest cost across their whole lifecycle is on operations and maintenance dependent accessibility calm seas. However, role climate change accessibility, thus operational cost, has not been resolved. Here we provide first study...
The effects of climate change are currently a red-hot issue in the scientific community. However, little attention has been paid to on wave and, particular, directionality. In this study, we developed methodology trend analysis and extrapolation mean climate. We used parameters typical rose: frequencies height intervals directional sectors. over time was estimated by means linear regression after applying transformation according nature (compositional) data. Then, extrapolated up 2050...
This study proposes a computationally inexpensive statistical method for modeling ocean wave heights, focusing particularly on heights in near-shore areas. A multiple linear regression is used to predict significant (Hs) using predictors derived from the sea level pressure (SLP) field, including use of squared SLP gradients represent geostrophic winds. One time step lagged Hs also included as predictor, which could be interpreted first order derivative spectral energy balance governing...
Abstract. In the context of wave climate variability, long-term alterations in storminess pattern Catalan coast (northwestern Mediterranean Sea) are analysed terms energy content and direction, on basis hindcast data (from 44-year time series). general, no significant temporal trends found for annual mean maximum energy. However, same analysis carried out separately different directions reveals a remarkable increase storm events from south, which is partly due to rise percentage such storms....
Abstract. The objective of the present work is to analyse how changes in wave patterns due effect climate change can affect harbour agitation (oscillations within port wind waves). study focuses on 13 harbours located Catalan coast (NW Mediterranean) using a methodology with general applicability. To obtain agitation, Boussinesq-type model used, which forced at boundaries by present/future offshore conditions extracted from recently developed high-resolution projections NW Mediterranean....

Abstract. In this paper changes in the wave pattern of Catalan coast are analyzed terms storminess and direction based on series 44 years hindcast data. The analysis is performed employing two different techniques: one resulting from combination regression bootstrapping other applying a Bayesian method. Although trends are, general, null, some locations there clear directional frequencies. These can significatively affect coastal hydrodynamics morphodynamics.
