    • Mean Period Total Swell

    Spectral mean wave period obtained using the reciprocal frequency moment 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.

    Mean Period Wind Waves

    Spectral mean wave period obtained using the reciprocal integral moment of the wind waves spectrum. The wind waves spectrum is obtained by only considering the components of the two-dimensional wave spectrum that are under the influence of the local wind. The integration is performed to infinitely high frequencies.

    Mean Wave Period

    Spectral mean wave period obtained using the reciprocal frequency moment of the full wave spectrum. The integration is performed over all theoretical frequencies up to infinity. Again, the frequency wave spectrum is obtained by integrating the two-dimensional wave spectrum over all directions.

    Mean Wave Period First Moment

    Spectral mean wave period obtained using the first frequency moment of the total swell spectrum. The integration is performed over all theoretical frequencies up to infinity. The frequency wave spectrum is obtained by integrating the two-dimensional wave spectrum over all directions.

    Mean Wave Period First Swell

    Spectral mean wave period obtained using the first integral moment of the total swell frequency spectrum. The integration is performed over all theoretical frequencies up to infinity. The total swell frequency spectrum is obtained by integrating the two-dimensional wave spectrum over all directions for all wave components that are no longer under the influence of the local wind (full spectrum without wind sea).

    Mean Wave Period Second Moment

    Spectral mean wave period obtained using the second integral moment of the frequency wave spectrum. The integration is performed over all theoretical frequencies up to infinity. The frequency wave spectrum is obtained by integrating the two-dimensional wave spectrum over all directions.

    mean_wave_period_second_moment:s

    Examples

    Mean Wave Period Second Swell

    Spectral mean wave period obtained using the second integral moment of the total swell frequency spectrum. The integration is performed over all theoretical frequencies up to infinity. The total swell frequency spectrum is obtained by integrating the two-dimensional wave spectrum over all directions for all wave components that are not under the influence of the local wind (full spectrum without wind sea).

    Examples

    Mean Wave Period Third Swell

    Mean wave period computed using the reciprocal frequency moment of the third most energetic partition of the swell spectrum.
    The 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 (full spectrum without wind sea).

    mean_wave_period_third_swell:s

    Examples

    Peak Wave Period

    The peak wave period is defined as the wave period associated with the most energetic waves in the total wave spectrum at a specific point. Wave regimes that are dominated by wind waves tend to have smaller peak wave periods, and regimes that are dominated by swell tend to have larger peak wave periods. 2
