    Smile waves

    When the wind and wave are in the same direction, a decrease of wave period and an increase of wave height are observed.How this happens?

    Thanks in advance

    Dear Remya

    It is because of the superimposition of wind seas with swells. During which the local winds (say, sea breeze) are stronger than synoptic winds, hence wind seas are higher than swells. We know that swell periods are higher (say, between 8 to 12 s) than wind sea periods (3 to 5 s). when they superimpose, the mean wave period decreases (bewteen 5 to 8), however due to strong local winds the wave height increases.

    Please refer the following paper, for more information:
