Closing a heat budget: effect of internal waves

摘要: Abstract Based on the accuracy and noise levels of today's moored instrument technology, it appears that we can estimate vertical heat flux its divergence in (or into) ocean if measure horizontal fluxes. However, do not know effect oceanographic (e.g. internal waves) calculation fluxes their divergence. In this study, magnitude error a for control volume due to presence waves is investigated. We used simple wave model ( W. Munk , Evolution physical oceanography MIT Press, pp. 264–291, 1981) generate time series velocity temperature data representative those from moorings method determine mean The size averaging were varied. Our results imply difference greater than 25 W m −2 between top bottom 40 km × could be determined periods 48h. found divergence, presented terms per unit area, increased linearly with extent decreased volume. time, δQ H ∞ (t avg ) − 1 2 .
