Abstract: Cirrus outflow from deep convection are analyzed as dynamically and thermodynamically active systems. The initial outflow is considered as an analog to wake collapse, in which a neutrally buoyant flow intrusion is flattened ...

Abstract: Observational results and theories suggest that the atmospheric energy spectrum is at least partly produced by quasi-two-dimensional turbulence generated by energy sources at both large and small scales. This hypothesis ...

Abstract: The stability of the two-dimensional boundary flow produced in a rotating tank with small inflow is investigated by means of perturbation analysis. The resulting differential eigenvalue problem is solved numerically both ...

Abstract: A three-dimensional buoyant convective element responds to the existence of mean vertical shear by developing rotation about a vertical axis, with the rotational kinetic energy abstracted from that of the mean flow. This ...

Abstract: Rotating ?supercell? thunderstorms are shown to be characterized by high helicity, the vector inner product of velocity and vorticity, which is obtained both from the mean flow in which they are embedded and from buoyancy ...

Abstract: The satisfactory numerical solution of the equations of fluid dynamics applicable to atmospheric and oceanic problems characteristically requires a high degree of computational stability and accurate conservation of certain ...

Abstract: A new entrainment closure for convectively mixed boundary layers, particularly those topped by stratocumulus clouds, is developed and calibrated against results of large eddy simulations carried out by C.-H. Moeng. The ...

Abstract: A pervasive issue in the analysis of clear and cloud-containing convectively mixed layers is how to predict their growth through entrainment. This paper deals largely with the definition of the interface with the upper ...

Abstract: A perturbation model is developed which is applicable to small-amplitude moist convective disturbances of scales ranging from those of squall lines t o tropical cyclones. In an extension of the works of Sy?no and Haque, ...
