An aircraft equipped with a new video camera designed to count ice crystals flew into the Hokuriku winter cumulus clouds which developed over the Japan sea during typical Monsoon weather. On one day we encountered cumulus clouds which formed many small ice crystals. There, a very high concentration of ice crystals in the size of 60/100 μm in diameter was measured when both large and small graupel were observed, while medium‐sized graupel were missing. It was proposed that ice crystals were shattered in the collision of large and small graupel, which have different ice surfaces formed by different modes.
