Abstract: The propagation of electromagnetic waves emitted from ground-based meteorological radars is determined by the stratification of the atmosphere. In extreme superrefractive situations characterized by strong temperature ...

Abstract: The oxidation of kerosene (Jet-A1) has been studied experimentally in a jet-stirred reactor at 1 to 40atm and constant residence time, over the high temperature range 800–1300K, and for variable ...

Abstract: The potential of the inclusion of two prognostic variables for cloud condensate and precipitation content in adjoint calculations has been investigated in the framework of Météo-France's operational spectral global model, ...

Abstract: A simple upper boundary condition for hydrostatic, Boussinesq models is derived from a linear internal wave theory, assuming a uniform stratification and no Coriolis effects. This condition is applied in a two-dimentional ...

Abstract: This paper first reviews the current status, issues, and limitations of the parameterizations of atmospheric large-scale and convective moist processes that are used in numerical weather prediction and climate general ...

Abstract: A third-order turbulence model of the marine stratocumulus layer, including cloud ensemble relations and detailed radiative computation, is used to study a case observed over the North Sea during the JASIN experiment. It ...

Abstract: This paper aims to develop and test a parameterization scheme for partial cloudiness, to be used in the framework of higher-order models of the turbulent planetary boundary layer. The proposed scheme is designed to be ...

Abstract: new parameterization able to diagnose lightning flash densities is proposed for the ECMWF Integrated Forecasting System, including its tangent-linear and adjoint versions. Total lightning densities are expressed as a ...
