大気・海洋結合モデルによる日本海の高潮・高波の数値解析

As a part of the intensive research on storm surges and high waves in Japan Sea, we conducted both tide observation data analysis and numerical simulation of weather and surge fields by the atmosphere-ocean coupled model for the severe storm in the central Japan Sea in February, 2008. It was made clear by numerical simulation of storm surge and data analysis that the range of surge heights generated by the storm that caused severe damage on the coastal structure, was 20 to 40cm. However, the actual tide record includes the long-period sea level changes, such as continental shelf seish, bay oscillation and surf beat, except wind waves.
