| 摘 要： | The scattering process, which means the redistribution of energy fluy in modenumber space, is analyzed for internal waves propagating from the abyssal ocean onto a subcritical strait slope and then a shelf region. In light of Wunsch＇s work, the waves are analytically expressed as superimposition of eigensolutions distribution of energy flux in the shelf region： one is the ratio of water depth in and the other is the ratio of the slope of the internal tide rays to the topographic energy flux distribution： the energy flux is focused around one modenumber or case, the range of modenumbers where energy flux is distributed is narrow. Two parameters have evident effects on the the shelf region to that in the abyssal ocean slope. Generally, there are two patterns of focused around two modenumbers. In any case, the range of modenumbers where energy flux is distributed is narrow.

| Abstract: | The scattering process, which means the redistribution of energy fluy in modenumber space, is analyzed for internal waves propagating from the abyssal ocean onto a subcritical strait slope and then a shelf region. In light of Wunsch's work, the waves are analytically expressed as superimposition of eigensolutions. Two parameters have evident effects on the distribution of energy flux in the shelf region: one is the ratio of water depth in the shelf region to that in the abyssal ocean and the other is the ratio of the slope of the internal tide rays to the topographic slope. Generally, there are two patterns of energy flux distribution: the energy flux is focused around one modenumber or focused around two modenumbers. In any case, the range of modenumbers where energy flux is distributed is narrow. |
