Some conclusions are given as follows : If one or several long cloud bands of over 500 - 1000km length involve into the depression, and TBB decreases under -70℃ ℃ with the domain of - 60 ℃ isoline extending to more than 3 x 4 degree latitudes, the tropical depression would, very possibly, develop into .

得出结论认为：如果有一条或几条长达５００～１０００ｋｍ以上的长云带卷入，且云顶黑体温度降低 到－７０℃以下，而-６０℃的范围扩大到３ｘ４个纬距以上，则热带低压很可能在２４ｈ以内发展成为热带 风暴－台风。
