Figure 92: Location of the two points of met-ocean data
The met-ocean information consists of hourly time series of the following parameters of the sea state, wind speed
and wind direction and sea level variability due to tide:
• Hs: Significant wave height (meters)
• Tm: Mean wave period (seconds)
• Fp: Peak frequency (Hz). Calculated from the one-dimensional frequency spectrum
using parabolic fit around the discrete peak
• θ Hs : Mean wave direction (degree., meteorological convention)
• W: wind speed at 10 meters above the sea surface (m/s)
• Wdir: Wind direction at 10 meters above the sea surface (degree., meteorological
convention)
• Tide: tidal level (m) without meteorological effects/storm surge
7.1.4. Wind climate
Two offshore databases are available - one is on the western side and the other on the eastern side of the area
of study. Each one has been explained below:
7.1.4.1. Western location
On the western side all wind directions are represented by the wind rose. This figure represents the wind speed,
the wind direction and the frequency of occurrence from 1979 to 2010.
In conclusion the predominant directions in these 31 years are west and northwest.
