Abstract: Linearized solutions are derived for the case of constant (negative) shear flow over an isolated, circularly symmetric hill and are evaluated for three characteristic wave regimes. Of particular interest is the three-dimensional ...

Abstract: A large-amplitude lee-wave event detected in radiosonde ascents during a field experiment in the Welsh mountains is described and wave characteristics are deduced. The synoptic-flow pattern accompanying this wave field is ...

Abstract: Analytical solutions are obtained to the linearized equations describing a particular class of directionally sheared flow over isolated hills or ridges. The flows are characterized by constant buoyancy frequency and vertical ...

Abstract: If the deviation of mean flow from mean temperature contours is small, it is shown that a part of the eddy heat flux can be separated out which circulates around eddy potential energy contours, and has a component up/down ...

Abstract: n improved stochastic kinetic energy backscatter scheme, version 2 (SKEB2) has been developed for the Met Office Global and Regional Ensemble Prediction System (MOGREPS). Wind increments at each model time step are derived ...

Abstract: nalysis of a high-resolution, convection-permitting simulation of the tropical Indian Ocean has revealed empirical relationships between precipitation and gravity wave vertical momentum flux on grid scales typical of earth ...
