Minor changes from Seifert and Beheng (2006): the power law relationships between x and D and between x and A are assumed and the terminal velocity is diagnosed using x, D, and A. | |
S14 (Seiki et al. 2014) | Cloud optical properties are updated from Mie scattering to non-spherical scattering. The heterogeneous ice nucleation scheme proposed by Meyers et al. (1992) is replaced by the scheme proposed by Phillips et al. (2007). |
S15 (Seiki et al. 2015b) | Homogeneous ice nucleation is newly implemented by referring to Ren and McKenzie (2005) and Kärcher et al. (2006). Values of the sticking efficiency at temperature lower than 253 K is limited to its value at 253 K in aggregation between ice hydrometeors. |
S15V (Seiki et al. 2015b) | The maximum vertical grid spacing is limited to 400Â m below an altitude of 20Â km. Accordingly, the number of vertical layers increases from 40 to 74. |
S15VH (Seiki et al. 2015b) | Horizontal grid size is refined from 14 to 7Â km. Accordingly, the model time step is changed from 30 to 15Â s. |
