X-band radar observation for the region of HORS research pier – located at Kashimanada coast – is conducted within October 2013 when three typhoons, namely 201326, 201327 and 201328, approached the area. Through FFT analyses of the radar images, variations of dominant frequencies and incident wave directions are estimated to illustrate the transition of the wave field during the storm sequence. Since the typhoons travelled quickly along the island, wave field shows drastic changes that are discussed in details.
