Saturation of the internal tide over the inner continental shelf. Part I: Observations

Broadly-distributed measurements of velocity, density and turbulence spanning the inner shelf off central California indicate that (i) the average shoreward-directed internal tide energy flux (〈FE〉) decreases to near 0 at the 25 m isobath; (ii) the vertically-integrated turbulence dissipation rate (〈D〉) is approximately equal to the flux divergence of internal tide energy (∂x〈FE〉); (iii) the ratio of turbulence energy dissipation in the interior relative to the bottom boundary layer (BBL) decreases toward shallow waters; (iv) going inshore, 〈FE〉 becomes decorrelated with the incoming internal wave energy flux; and (v) 〈FE〉 becomes increasingly correlated with stratification toward shallower water.

ANALYSIS OF CLOUD DROPLET SIZE SPECTRA BY JENSEN-SHANNON DIVERGENCE

The purpose of this work is to use the divergence of Jensen-Shannon to compare spectra of cloud droplet sizes corresponding to different experimental conditions. Results of laboratory measurements are analyzed in which the diameter of droplets, produced by means of an ultrasonic nebulizer, are determined, subject to different movement conditions within a "cloudbox". The turbulence energy dissipation rate is particularly considered. The droplet spectra were approximated by the density kernel method.
