    Experiments have shown that if a supercooled drop is accreted on to a rimer in such a way that it lands on an already frozen smaller droplet then it may develop a protuberance as it freezes, presumably because the heat loss is fairly symmetrical. These protuberances were found in the temperature range -3 to -8oC, and their probability of production reached a maximum at -5 to -6oC of 1 for every 20 drops accreted. Due to the strong parallelism between the conditions required for protuberance production and ice splinter ejection during riming we suggest that the splinters are a result of explosive fragmentation of about 1% of the protuberances formed. This idea is supported by some experimental evidence.- from Authors
