Progress of research on health effects of environmental tobacco smoke on non - smoking population 7月22日时段的卫星云图进行普查发现影响淮河流域的中尺度对流系统
In the unstable large scale atmosphere , trigger conditions determine when and where the convections come into being 在不稳定的大尺度环境中,触发条件决定了对流系统在何时何地发生。
The cloud model gives a complete structure of the partical microphysics of a convective cloud system over chinese mainland 云模式给出了中国陆地上两个对流系统的粒子微物理特征的完整结构。
A mesoscale convective system which happened around shangdong province in the middle spring 2003 induced heavy rainfall 2003年4月中旬发生在山东一带的中尺度对流系统引发了一次罕见的春季大暴雨。
However , the cg flash rate in severe convective systems with organized structure is high and has peak value before mature stage 而有组织的强对流系统地闪频数较高,在发展阶段出现地闪频数峰值。
