A test of numerical instability and stiffness in the parametrizations of the ARPÉGE and ALADIN models
Meteorological numerical weather prediction (NWP) models solve a system of partial differential equations in time and space. Semi-lagrangian advection schemes allow for long time steps. These longer time steps can result in instabilities occurring in the model physics. A system of differential equat...
