Abstract

We present a number-density advection based method designed to calculate the condensation/ evaporation of cloud droplets. An Eulerian-in-radius discretization scheme is adopted, making the present model suitable for use in the spectral bin method for cloud microphysics. The mass advection equation is solved using the constrained interpolated profile-conservative semi-Lagrangian with rational function (CIP-CLSR) scheme, In order to evaluate the present method based on the CIP-CSLR scheme, we performed a condensation growth calculation using the present method and conventional methods, and then compared the results. The comparison revealed the advantages of the present method in numerical accuracy, numerical stability, conservation and computational cost.
