    1818instead of ''θ'' as described in Sect. [wiki:doc/tec/gov governing equations]. Since ''q'' and ''θ'',,l,, are conserved quantities for wet adiabatic processes, condensation/evaporation is not considered for these variables.

     20PALM offers three different schemes for the treatment of liquid phase microphysics. The Kessler
    2021Liquid phase microphysics are parametrized following the two-moment scheme of [#seifert2001 Seifert and Beheng (2001],[#seifert2006  2006)], which is based on the separation of the droplet spectrum into droplets with radii < 40 μm (cloud droplets) and droplets with radii ≥ 40 μm (rain droplets). The model predicts the first two moments of these partial droplet spectra, namely cloud and rain
