Beach profile evolution under storm sequence forcing presents an emerging research topic that has only been investigated at a limited number of sites. The occurrence and effects of storm sequencing on beach profile evolution are studied at Hasaki Beach, Japan, using weekly beach profile and two-hourly offshore wave measurements. During the 25-year study period, the supratidal beach at Hasaki is subjected to long-term accretion and steepening while the shoreline shows a long-term oscillation. In addition, oscillations of the supratidal beach volume and the shoreline at semi-annual and annual intervals are identified, which are largely controlled by the variability of the wave height. Hasaki Beach is subjected to frequent storms that often cluster in sequences, especially during the extra-tropical cyclone season (January to March). The majority of storms and sequences generate erosion of the beach above the low water level but some also lead to recovery. Despite a tendency for storms and storm sequences with larger power to cause more erosion, the present data does not demonstrate increased beach erosion by storm sequences. Following these findings, the tendency of the beach to evolve towards equilibrium and the importance of the antecedent beach morphology are demonstrated.

风暴序列强迫下的海滩剖面演变提出了一个新兴的研究主题，仅在有限的地点进行了调查。在日本Hasaki海滩，使用每周的海滩剖面和每两个小时的海上波浪测量研究了风暴序列的发生及其对海滩剖面演变的影响。在为期25年的研究期内，Hasaki的滨上海滩经历了长期的积聚和陡峭，而海岸线则呈现出长期的振荡。另外，识别出上半年海滩体积和海岸线每半年一次和每年一次的振荡，这在很大程度上受波浪高度的变化控制。早崎海滩（Hasaki Beach）经常遭受暴风雨袭击，暴风雨通常会按顺序聚集，特别是在温带气旋季节（1月至3月）。大多数暴风雨和暴风雨都会在低水位以上造成海滩的侵蚀，但也有一些会导致恢复。尽管有发生风暴的趋势，并且大功率的暴风雨序列会引起更多的侵蚀，但目前的数据并未显示出暴风雨造成的海滩侵蚀增加。根据这些发现，证明了海滩向平衡方向发展的趋势以及先前海滩形态的重要性。
