Aggregate terminal velocity/temperature relations

Power-law relationships for particles having equivalent volume diameters of 0.5 - 20 mm are computed for the temperatures -1°, -5°, and -10°C. Fall speeds increase with temperature. Comparison with relationships found in the literature suggests that temperature-dependent relations may be surrogates for relations based on aggregate composition (e.g., plates, columns, or dendrites) and the degree of riming.
