| Abstract | Analytic approximations of the binary collision rates of hydrometeors are derived for use in bulk micro- physical parameterizations. Special attention is given to non- spherical hydrometeors like raindrops and snowflakes. The terminal fall velocity of these particles cannot be sufficiently well approximated by power-law relations which are used in most microphysical parameterizations, and therefore an im- proved formulation is needed. The analytic approximations of the bulk collision rates given in this paper are an alterna- tive to look-up tables and can replace the Wisner approxima- tion, which is used in many atmospheric models. |
