The supersaturation dependences on the slope of growth hillocks formed on the {1010} face P_P and the {0001} face P_B of ice crystals grown in air at -28.5℃ and low supersaturation were measured to study the formation mechanism of platelike ice crystals growing under this condition. As a result, it was found that both the {1010} and {0001} faces of plate-like ice crystals grown at -28.5℃ and low supersaturation grew by the Burton-Cabrera-Frank (BCF) mechanism, and when the relationship P_P>P_B held, plate-like ice crystals grew.
