... ABSTRACT In ISOPE’2019, the first intercomparison of wave reanalysis products (ERA5 and CFSR-W) was presented (Stefanakos, 2019). In the present work, this intercomparison is further extended by including global wave reanalysis product WAVERYS, which comes from Copernicus Marine Service (CMEMS...

... ABSTRACT In this work an intercomparison of two wave reanalysis products, namely ERA5 and CFSR-W (WW3 hereafter), is presented. The datasets are assessed by means of several statistical features, such as seasonal variability, quantiles of the probability distribution, annual and inter-annual...

... reanalysis. INTRODUCTION The rate of Arctic sea ice retreat during boreal summer is accelerating. In the last few decades, the ice-covered sea area has reduced by a few million square kilometers (Walsh 2014). Alternatively, the ice-free seas where wind-waves can be generated has increased. In latitudes...

... structures under fatigue constraints. It is shown that performing reanalysis of the jacket structures, using performance data from earlier analyses in parallel to the simulation-based analysis process requires a smaller number of iterations for obtaining improved designs. Thus the use of reanalysis within...

... ABSTRACT: We compare wave model results in the North Pacific using different wind reanalysis data which are ECMWF 40-year Reanalysis and NCEP/NCAR Reanalysis. The monthly mean difference of significant wave heights between these wave model results is significant from the Japanese Islands...

... ABSTRACT The recently completed NCEP Climate Forecast System Reanalysis (CFSR) from 1979 to 2009 used the NCEP coupled atmosphere-oceanland surface-sea ice system. This paper describes the sea ice concentration data used and how sea ice concentration is assimilated in the CFSR. The record...

... nonlinear equation of motion are employed. One is the direct method using the reanalysis approach to accelerate the solution, and the other is the modal method using eigen-modes of the elastic structure. Through the analysis of VLFS unit of 350m long, the applicability of the modal method to the collapse...

An algorithm of repeated sensitivity analy- sis is proposed to obtain a rational reanalysis solution for large changes in design variables, and is incorporated into the optimiza- tion process.
