In this study, in-situ observations of ice hydrometeors acquired in TCs, storms, depressions and waves during the NASA African Monsoon Multidisciplinary Analyses project, the Convection and Moisture Experiment-4, and in Hurricanes Norbert (1984) and Emily (1987) are fit to gamma distributions to determine how the intercept (No), slope (l) and shape (m) parameter vary with cloud and meteorological parameters such as the total water content (TWC), vertical velocity (w), temperature (T), and TC stage of development. The derived relationships of No, l and m with TWC, w and T are compared against relationships found using data collected in other tropical and mid-latitude locations. Implications for the representation of cloud microphysics in hurricane models are discussed.
