| Research Abstract |
During early spring time, the west coast area of Kyushu has suffered from the seiche disasters locally called Abiki. This study investigates the mechanism of the meteorologically generated secondary oscillations by means of the field measurements and numerical analyses. Two series of seasonal field observations were conducted at Urauchi bay in Koshiki Is., Kagoshima Prefecture. Numerical analyses for the three dimensional atmospheric fields over the East China Sea were conducted using an advanced meso-scale model. The oceanic fields under the atmospheric disturbances were also analyzed to clarify the resonant mechanism in offshore as well as coastal areas. Close discussion correlating the findings of field measurements with those of the numerical analyses has revealed a series of the mechanism throughout generation, development and amplification under the air-sea and geometric resonance.
