“…The predictions of ocean waves are very sensitive to the quality of the forcing wind fields used as has been demonstrated by many authors (Teixeira et al 1995;Holthuijsen, et al 1996;Ponce de Leon and Ocampo-Torres 1998;Cavaleri and Bertotti 2006;Ponce de León and Guedes Soares 2008;Campos and Guedes Soares 2016a) as well as current models and oil spill models. Hence, reliable and good quality wind reanalyses are of high importance in several applications.…”

“…Campos and Guedes Soares (2016a) performed an initial evaluation and comparison between HIPOCAS (REMO) and ERA reanalyses (ERA-40 and ERA-Interim) for wind speeds and wave heights. As both projects of HIPOCAS and ERA used the same wave model, Campos and Guedes Soares (2016a) discuss the impact of wind differences on the wave fields, showing stronger winds of HIPOCAS (REMO) at high latitudes, which led to higher values of wave heights especially at eastern longitudes close to Europe.…”

This paper evaluates three surface wind reanalyses in the North Atlantic Ocean: Climate Forecast System Reanalysis (CFSR/NOAA), ERA-Interim/ECMWF and the Hindcast of Dynamic Processes of the Ocean and Coastal Areas of Europe (HIPOCAS) based on the regional atmospheric model (REMO). The assessment is performed using satellite data from the GlobWave Project. The first part of this study compares the reanalyses in spatial and temporal domains. Furthermore, the analysis is also divided into overall conditions and extreme events. The second part evaluates each reanalysis independently using satellite data. In order to compare and evaluate the three datasets, coincident periods and grid domain were determined, which corresponds to the interval between 1979 and 2001, latitudes between 15°and 72°North and longitudes between 66°West and 7°East. The comparison results show that under calm winds the agreement among reanalyses is good. However, an increasing difference is found under extreme conditions. For extreme events, HIPOCAS (REMO) has the strongest winds, followed by CFSR and ERA-Interim. The assessment using measurements indicates underestimation of winds at mid-high latitudes above 45°North and overestimation at low latitudes. The monthly analysis suggests a strong seasonal cycle with overestimation of all reanalyses in the summer and underestimation in the winter. The lowest errors and best performance was obtained by CFSR, followed by HIPOCAS (REMO) at mid-high latitudes and ERA-Interim at low latitudes. A significant underestimation of ERA-Interim for the peak of the storms was found, which can be associated with its coarse time and space resolution. ARTICLE HISTORY

“…Historically, three series of data have been produced, supported by three node meshes: the WASA nodes that have become obsolete due to the age of the models used; the WANA nodes (1995 onwards) [16]; and the SIMAR-44 nodes (1958-2001) (superimposed on the WANA) both fully operational. SIMAR-44s were obtained in the year 2000 by the European HIPOCAS project [17] using historical weather charts dating back to 1958. In a direct way, they measure the five wave parameters in addition to the wave height/period ratios so important for these calculations.…”

Maritime Climate in the Canary Islands and its Implications for the Construction of Coastal Infrastructures

Islands are isolated systems that depend on maritime trade for their subsistence. Efficient, durable and structurally reliable port infrastructures are essential for the economic and social development of islands. However, not all port infrastructures are designed in the same way. They can vary, depending on whether they are built on continental land, built on non-volcanic islands or built on volcanic oceanic islands (such as the Canary Islands, Spain). The latter islands are the subject of this study due to their specific features, construction difficulties and the importance of sound maritime infrastructures. The maritime climate of an area consists of the wave and storm regimes that affect it and, from these, the coastal dynamics and coastal formations of that area can be studied. For this reason, historical data were collated on significant directional wave heights from 1958 to 2015 from several WANA-SIMAR points in the virtual buoy network of State Ports of Spain located near the Canary Islands. These data have been studied to obtain the maximum directional wave heights (Hs) at each point. With this analysis, we have obtained useful summary tables to calculate wave height by a graphic method that transforms the distribution function into a line drawn on probabilistic paper, using reduced variables. This enables adjustments to be made by linear regression and minimum square methods to facilitate planning and design of maritime infrastructures in a reliable way.
