Abstract: Three-dimensional turbulence occurs mainly in convective clouds and in the atmospheric boundary layer. Two-dimensional turbulence is a model for the statistical features of large-scale flows in the atmosphere. The differences ...

Abstract: Since eddies in turbulent flows are a dense collection of very short wave packets, their position and wavenumber (or lifetime and frequency) cannot be determined without ambiguity. The spectral width of eddies is about an ...

Abstract: This paper deals with the problem of fully developed free convection in the atmospheric boundary layer. In free convection, the height of the Ekman layer is much larger than the absolute value of the Monin-Oboukhov length. ...

Abstract: This paper explores the practical consequences of the asymptotic nature of the logarithmic wind profile in neutral, barotropic, planetary boundary layers. Recent developments in boundary-layer theory have shown that the ...

Abstract: The differential equations governing the strength ? (a potential temperature difference) and the height h of inversions associated with dry penetrative convection are considered. No assumptions on the magnitude of the ...

Abstract: It is likely that several features of the mid-latitude circulation in the earth's atmosphere wig also be observed in two-dimensional, nondivergent flow with buoyant forcing and surface friction. Properly scalled, buoyancy ...

Abstract: In this paper we develop an abbreviated model for the pressure-gradient velocity correlation terms in the equations for the Reynolds-stress components in the neutral boundary layer. The model contains three terms: a nonlinear ...

Abstract: The budget of turbulent kinetic energy at the base of the inversion which caps the daytime atmospheric boundary layer depends on the lapse rate of potential temperature in the air aloft. The principal gain term in the ...
