Measurements of atmospheric turbulence made over the Arctic pack ice during the Surface Heat Budget of the Arctic Ocean experiment (SHEBA) are used to determine the limits of applicability of Monin-Ob...
Forming Planetesimals by Gravitational Instability: I. The Role of the Richardson Number in Triggering the Kelvin-Helmholtz Instability
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
Gravitational instability (GI) of a dust-rich layer at the midplane of a gaseous circumstellar disk is one proposed mechanism to form planetesimals, the building blocks of rocky planets and gas giant ...
Statistics of Richardson Number and Instability in Oceanic Internal Waves

2009/2/8
The probability density function (pdf) of Richardson number in a Gaussian internal-wave field is derived. It is found to compare well with available data. The pdf depends on only parameter λ, the rms ...
Richardson Number Profiles over the Continental Shelf
Continental Shelf Richardson Number Profiles
2009/2/6
The seasonal mid-water thermocline over the continental shelf has been examined with the aid of an oceanographic Richardson Number Probe. The overall Richardson number of this stable layer was found t...
