Empirical Formulation for Ice Crystal Fragmentation by Sublimation Breakup Study

This study by Akash Deshmukh at Lund University delves into the empirical formulation for the number of ice crystal fragments resulting from sublimation breakup. It discusses secondary ice production mechanisms, challenges in numerical formulation, observational bases, previous studies, and cloud development phases related to ice crystal growth and sublimation. The research highlights factors influencing ice crystal sublimation such as crystal habit, size, temperature, and relative humidity.
