在日本在 Seto 内陆海的广岛海湾产生的 Nontidal 海水平变化在各种各样的时间规模上被学习,从亚 tidal (到 1 个月的 2 d ) 到内部年度的规模(> 2 年) 。全部的海水平变化生产 12.5 厘米的标准差(性传播疾病) 。在广岛海湾的海水平变化的内部年度的部件与 3.4 厘米的性传播疾病震荡,形成 4.9 mm/a 的一个长期的趋势。海水平变化的性传播疾病为 intra 季节的(到 8 个月的 1 个月) 是为季节的部件(到 2 年的 8 个月) 和 4.7 厘米的 9.8 厘米。有 4.2 厘米的性传播疾病的重要的海水平变化也发生在亚 tidal 范围。特殊注意对亚 tidal 海水平变化被给予。upwelling 和联系的短暂的海铺平沿着广岛海湾的北方海岸产生的变化,这被发现(开向南方) 由大在北方的风,在亚 tidal 海水平变化起一个重要作用。当由通过太平洋离开 Kii 半岛的台风引起了时,短暂的海水平变化是在大多数情况中的超过 10 厘米,在广岛海湾的大约 400 km 东方定位了。合理的海水平变化被压力力量的平衡在学习领域的向陆、近海的边界评估。
Nontidal sea level changes generated in Hiroshima Bay of the Seto-Inland Sea in Japan are studied over various time scales, from the sub-tidal (2 d to 1 month) to inter-annual scales (〉2 years). The total sea level variation produces a standard deviation (STD) of 12.5 cm. The inter-annual component of the sea level variation in Hiroshima Bay oscillates with a STD of 3.4 cm, forming a long-term trend of 4.9 mm/a. The STD of the sea level variation is 9.8 cm for the seasonal component (8 months to 2 years) and 4.7 cm for the intra-seasonal one (1 month to 8 months). Significant sea level variations with a STD of 4.2 cm also occur in the sub-tidal range. Special attention is paid to the sub-tidal sea level changes. It is found that the upwelling and associated transient sea level changes generated along the north coast of Hiroshima Bay (opened southward) by the strong northerly wind, play a significant role in sub-tidal sea level changes. The transient sea level changes are over 10 cm in most cases when caused by typhoons that pass through the Pacific Ocean offthe Kii Peninsula, located at about 400 km east of Hiroshima Bay. Reasonable sea level changes are evaluated by the balance of pressure forces at the onshore and offshore boundary of the study domain.
