分析纵向云带环境下,海南岛降水过程的相关系统配置和物理量的时间演变特征。
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。
