Abstract: Horizontally oriented plates in clouds generate a sharp specular reflectance signal in the glint direction, often referred to as ?subsun.? This signal (amplitude and width) may be used to analyze the relative area fraction ...

Abstract: ike any fluid heated from below, the atmosphere is subject to vertical instability that triggers convection. Convection occurs on small time and space scales, which makes it a challenging feature to include in climate ...

Abstract: A new dynamical subgrid model for turbulent flow is used to derive the structure of the heat and momentum fluxes, mean wind and temperature profiles, and temperature and velocity variances, as a function of the Richardson ...

Abstract: A new dynamical subgrid model for turbulent flow in the surface layer of the planetary boundary layer is presented. In this formulation, the flow is decomposed into small (subgrid) and large (resolved) scales in the spirit ...

Abstract: AbstractAtmospheric motions are governed by turbulent motions associated to nontrivial energy transfers at small scales (direct cascade) and/or at large scales (inverse cascade). Although it is known that the two cascades ...
