Geographical location of the Barents Sea and the sea area within the inner sector is the selected domain for the statistical study

Annual average, mean monthly maximum (April), minimum (September) distributions of the sea ice concentration and the ice zone partitions. In the ice-free zone, the points labeled from P1 to P1 are selected for further wind climate and energy analysis.

Spatial distributions of annual average wind speed at 10 m

Spatial distributions of mean seasonal wind speed at 10 m from winter to autumn

Wind roses from P1 to P7 in the Barents Sea. The color scale represents wind speed classification

Spatial distributions of annual average wind speed and power density at 100 m

Spatial distributions of mean seasonal wind speed at 100 m from winter to autumn

Spatial distributions of mean seasonal wind power density at 100 m from winter to autumn
