Abstract: In a recent paper, Canuto et al. made a crucial contribution to modeling mixing in stably stratified flows by discovering that a modification to one of the closure constants can push the critical gradient Richardson number ...

Abstract: Two-equation models are being increasingly used to model turbulence in geophysical flows. A salient aspect of these flows is the stable gravitational stratification, which implies that turbulent fluctuations can generate ...

Abstract: Cheng, Canuto, and Howard have presented a second-moment closure PBL model that appears to overcome some of the shortcomings of the existing Mellor and Yamada?type closure models. This note demonstrates that with a slight ...

Abstract: Mixing in the free atmosphere above the planetary boundary layer is of great importance to the fate of trace gases and pollutants. However, direct measurements of the turbulent dissipation rate by in situ probes are very ...

Abstract: This note describes the development of a method for obtaining high vertical resolution (meter scale) measurements of basic meteorological quantities and turbulent overturns, using radiosondes with slow ascent rates. Although ...
