基于2012年在福建闽江口东部白犬列岛海域利用AWAC仪器观测的波浪数据,统计分析了该海域的波浪特征,并由能量谱积分计算了波功率密度(Pw).与深水条件下Pw和波高、周期的近似关系相比,其比例系数存在一定差异.以不同波高和不同周期两两组合与对应Pw进行比较,分别求其比例系数,结果表明:T1/10和Tm02所对应的近似关系较为稳定,Tz和Tp对应的关系变化较大,稳定性最好的为Hs和T1/10的组合,α值为0.46. |

Abstract: |
Based on the wave observation by AWAC in 2012 near Bai-quan islands,in the east of Min-jiang Estuary,the wave characteristics are analyzed and the wave power are calculated using spectrum integral. Compared with the approximate relationship of wave power with wave height and period in deep water,the coefficients appear a slight difference. This paper takes the corresponding coefficients in different wave height-ranges and period-ranges as a combination,and finds that the corresponding approximate relationship of T1/10 or Tm02 is much stable than Tz or Tp. The most optimal approximate formula is the combination of Hs and T1/10 with a coefficient of 0.46. |
