| | 30 | Two-moment cloud physics (Seifert and Beheng, 2006) have been implemented. Therefore, two new prognostic equations (nr: rain drop number density; qr: rain water content) and associated basic output quantities are introduced (advec_ws, average_3d_data, boundary_conds, check_parameter, data_output_2d, data_output_3d, flow_statistics, init_3d_model, init_cloud_physics, modules, netcdf, parin, prognostic_equations, read_3d_binary, read_var_list, sum_up_3d_data, swap_timelevel, time_integration, user_actions, write_3d_binary, write_var_list). Microphysical tendencies affecting the prognostic equations of liquid water potential temperature, specific humidity, rain drop number density and rain water content are computed in the new module microphysics (additionally changes: calc_liquid_water_content, Makefile). According to the CFL criterion, the timestep has to be reduced in case of precipitation (timestep). |
