| 中文摘要: |
| 本文对2008年中国沿岸验潮站水位,沿岸风,气温和气压进行了小波分析,结果显示冬季寒潮激发了三次海表面振荡事件.第一次事件发生于1月9-21日,其海表面振荡周期分别是1.6-5.3和7.0-16.0 d,功率密度分别为0.04-0.05和0.10-0.15 m2·d.第二次事件发生于2月5-18日,其海表面振荡周期为2.3-3.5 d,功率密度为0.03-0.04 m2·d.第三次事件发生于2月20-3月8日,其海表面振荡周期为1.5-4.3 和6.1-8.2 d,其功率密度分别为0.08-0.11 和0.02-0.08 m2·d.海表面振荡信号沿着海岸由浙江向南传播至广东,其传播相速度从坎门到平潭为9-29 m/s,从厦门到惠州为5-11 m/s,从惠州到水东为11-22 m/s.海表面振荡的频散关系显示该信号为陆架波. |
| 英文摘要: |
| This study applies the wavelet analysis to the tidal gauge records, alongshore winds, atmospheric temperature and pressure along the China coast in winter 2008. The analysis results show three events of sea level oscillations (SLOs) on the shelf induced by winter storms. The first event occurred from January 9 to 21. The SLO periods were double-peaked at 1.6-5.3 and 7.0-16.0 d with the power densities of 0.04-0.05 and 0.10-0.15 m2·d, respectively. The second event occurred from February 5 to 18. The SLO period was single-peaked at 2.3-3.5 d with power density of 0.03-0.04 m2·d. The third event occurred from February 20 to March 8. The SLO periods were double-peaked at 1.5-4.3 and 6.1-8.2 d with the power densities of 0.08-0.11 and 0.02-0.08 m2·d, respectively. The SLOs propagated along the coast from Zhejiang in north to Guangdong in south. The phase speeds ranged about 9-29 m/s from Kanmen to Pingtan, 5-11 m/s from Xiamen to Huizhou and 11-22 m/s from Huizhou to Shuidong. The dispersion relation of the SLOs shows their nature of coastal-trapped wave. |
