● どうして有明海の干満差は日本で一番なの？
Why does the Ariake Sea show the highest tidal difference in Japan?
有明海は巨大な内海で、入り口が極端に狭く、奥行きが深いという、独特な地形から、
有明海の持つ固有振動周期と、月の引力などによる干満の周期（潮汐周期）が
共振しやすい状態になり、日本最大の干満差を引き起こすのです。
The phenomenon is caused by the resonance between the natural oscillation period of the Ariake Sea and the tidal cycle by the moon’s gravitation due to the unique
terrain of the Ariake Sea, which is a large inner bay with extremely narrow and deep entrance.
