Abstract
Numerical implementation of CTM should satisfy a set of contradictory requirements related to the quality of the model predictions, minimization of the volume of computations, applicability of the model to different meteorological situations etc. In this paper we present several numerical recipes that were proven to be efficient in constructing CTMs and dispersion models developed at the Voeikov Main Geophysical Observatory (St. Petersburg, Russia) and Finnish Meteorological Institute (Helsinki, Finland). Assuming splitting, we discuss approximations of the physical processes separately but they can be used jointly as well.
