  1. The parameter Psaut_β0 and Γ_saut are concerning the autoconversion rate of cloud ice to snow [Eq. (52) and (53) in Tomita 2008], and Γ_sacr is concerning accretion rate of cloud ice by snow [Eq. (39) in Tomita 2008], cnst_VT_qi is the constant for terminal velocity of cloud ice (VT_qi), cr and cs are the coefficients of terminal velocity of rain and snow, respectively [Eq. (28) in Tomita 2008], and C_d is concerning the terminal velocity of graupel. In E, VT_qi was formulated as VT_qi = 3.29 (ρqi)0.16 [Eq. (5) of Heymsfield and Donner 1990], where ρ is the air density (kg m−3) and qi is cloud ice content (kg kg−1)
