The sub-grid-scale parameterization of clouds is one of the weakest aspects of weather and
climate modeling today, and the explicit simulation of clouds will be one of the next major …

An integrated forecasting and data assimilation system has been and is continuing to be
developed by the Meteorological Research Branch (MRB) in partnership with the Canadian …

The numerical resolution of kinetic equations and, in particular, of Vlasov-type equations is
performed most of the time using particle in cell methods which consist in describing the time …

A new technique for climate simulations and projections has emerged over the past 15 years
that allows to reach unprecedented spatial resolution at an affordable computing cost …

EULAG (Eulerian/semi-Lagrangian fluid solver) is an established computational model for
simulating thermo-fluid flows across a wide range of scales and physical scenarios. It is …

Conservative Split-Explicit Time Integration Methods for the Compressible Nonhydrostatic
Equations in: Monthly Weather Review Volume 135 Issue 8 (2007) Jump to Content Jump to …

We present a semi-Lagrangian method for advection–diffusion and incompressible Navier–
Stokes equations. The focus is on constructing stable schemes of second-order temporal …

A new numerical method for solving geometric moving interface problems is presented. The
method combines a level set approach and a semi-Lagrangian time stepping scheme which …

A semi-implicit, semi-lagrangian algorithm suitable for the simulation of the dry, adiabatic,
nonhydrostatic atmospheric dynamics is introduced and analysed. Height is used as vertical …

A Cartesian, small-to mesoscale nonhydrostatic model is extended to a rotating
mountainous sphere, thereby dispensing with the traditional geophysical simplifications of …
