Mean Wave Direction

Spectral mean direction in degrees over all frequencies and directions of the two-dimensional wave spectrum.
Please note that we are using the meteorological convention to define directions (Read more here).

Mean Direction Wind Waves

Spectral mean direction over all frequencies and direction of the wind waves spectrum.
The wind waves spectrum is obtained by only considering the components of the two-dimensional wave spectrum that are still under the influence of the local wind.
Please note that we are using the meteorological convention to define directions (Read more here).

Mean Direction Total Swell

Spectral mean direction in degrees over all frequencies and directions of the total swell spectrum.
The total swell spectrum is obtained by only considering the components of the two-dimensional wave spectrum that are not under the influence of the local wind.
