摘　　要：利用基于FVCOM(Finite Volume Coastal Ocean Model)模式同化沿岸验潮站数据的高分辨率潮汐数值模型结果,分析研究了包含中国近海、日本海和鄂霍次克海在内的西北太平洋海域全日、半日分潮的潮能通量与耗散。西北太平洋的潮波能量分3支,分别传入鄂霍次克海、东海和南海。传入东海的半日潮波能量是传入南海的3倍左右;传入南海的全日潮波能量是传入东海的5倍多。传入中国东部海域的M2分潮能中,有64.3%耗散在东海,32.4%耗散在黄海,仅有3.2%耗散在渤海;而K1分潮能中分别有48.2%、31.4%及7.1%耗散在东海、黄海及渤海。进入南海的潮能中,仅有32.7%的M2分潮能和38.3%的K1分潮能耗散在南海的北部海域,另有23.9%的M2分潮能进入并耗散在台湾海峡,其余则进入南海南部。传入日本海的太平洋潮能很少。鄂霍次克海消耗的全日潮能是半日潮能的2倍。A Finite Volume Coastal Ocean Model （FVCOM） that assimilated tidal gauge data was used to study the tidalenergy flux and dissipation in the Northwest Pacific, including the China seas, the Japan Sea （JS） and the Sea of Okhotsk （SO）.Most of the tidal energy in the Northwest Pacific is transmitted to the East China Sea （ECS）, the South China Sea （SCS）andthe SO. The semi-diurnal tidal energy transported into the ECS is three times larger than that transported into the SCS; whilstthe diurnal tidal energy transported into the SCS is five times of that transported into the ECS. In the waters east of China,64.3% of M2 semi-diurnal tidal energy is dissipated in the ECS,32.4% in the Yellow Sea （YS）, and only 3.2% in the Bohai Sea（BS）. For K1 diurnal tide, 48.2%, 31.4% and 7.1% of the tidal energy are dissipated in the ECS, the YS and the BS,respectively. Among the tidal energy transported into the SCS, 32.7% of M2 and 38.3% of K1 are dissipated in the northernregion, 23.9% of M2 is transported into and dissipated in the Taiwan Strait, and the rest enters the southern SCS. Little tidalenergy is transported from the Pacific Ocean into the JS. The dissipation of diurnal tidal energy in the SO doubles that of thesemi-diurnal tidal energy.
