“…This causes the ice crystals to grow at the expense of the evaporation of cloud droplets which is referred to as the Wegener-Bergeron-Findeisen process (Wegener, 1911;Bergeron, 1935;Findeisen, 1938). The complexity of phase partitioning adds to difficulties simulating MPCs in models (e.g., McCoy et al, 2016;Matus and L'Ecuyer, 2017) where experimental observations could reduce uncertainties (see e.g., Baumgardner et al, 2011;Mahrt et al, 2019). In the evolution of a MPC, the ice phase plays an important role as it controls precipitation initiation and consequently cloud life time (see e.g., Field and Heymsfield, 2015;Heymsfield et al, 2020).…”
