Abstract

In this study, atlases of wave characteristics and wave energy for the Barents Sea have been generated for the years from 1996 to 2015 based on ERA-Interim datasets from the European Centre for Medium-Range Weather Forecasts (ECMWF). The wave power resources in the Barents Sea can be exploited with sea ice extent declining in recent years. The entire Barents Sea has been divided into multi-year sea ice zones, seasonal sea ice zones and open water zones according to the 20-year averaged sea ice concentration. In the entire domain, the spatial distributions of the annual averaged and mean monthly significant wave heights and wave energy flux are presented. For the open water zones, 15 points have been selected at different locations so as to derive and study the wave energy roses and the inter-annual wave power variation. Moreover, the correlations between the wave energy period and the significant wave height are shown in the energy and scatter diagrams. The maximum wave power occurs in the winter in the western parts of the Barents Sea with more than 60kW/m. The wave energy can therefore be exploited in the open water zones.

巴伦支海波浪特征和波能评价
在这项研究中,基于欧洲中期天气预报中心(ECMWF)的ERA-Interim数据集,绘制了1996年至2015年巴伦支海的波浪特征和波能地图集。随着近年来海冰面积的减少,巴伦支海的波浪能资源可以开发利用。根据20年平均海冰浓度,将整个巴伦支海划分为多年海冰区、季节性海冰区和开放水域。在整个区域,给出了年平均和月平均有效波高和波能通量的空间分布。开放水域在不同位置选取15个点,推导和研究波浪能增量和波浪能年际变化。此外,能量图和散点图显示了波浪能量周期与有效波高的相关关系。冬季,巴伦支海西部的波浪功率最大,超过60kW/m。因此,波浪能可以在开阔水域被利用。
