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。
The layout of the dissertation is as follows : the first chapter is to model and visualize the convective heat and mass transport 主要内容分为七章,研究要点如下:第一章探讨如何描述对流系统中热与质的传输过程
Stream ascended strongly in the center of the mesoscale vortex and the structure of lower - level convergence and upper - level divergence are very favorable to the generation and development of the mesoscale convective system 该低涡中心存在着强上升运动,低层辐合高层辐散的配置非常有利于中尺度对流系统的发生发展。
Based on the analysis of geothermal geology and hydrothermal convection system , the hot groundwater is formed from the mixing of the deep - circulating high - temperature structural - fissure water with the shallow circulating ordinary - temperature karstic water in the hydrothermal convection system 根据地热地质条件及水热对流系统分析,地下热水是在水热对流系统中由深循环高温构造裂隙水与浅循环常温岩溶水混合而成。
The brightness temperature is highly related to the density of ice hydrometeor . since the convective cloud system is tilted , and the viewing angle is oblique , the area displacement between ice hydrometeor and the surface rainfall rate makes the relation between tb and surface rainfall rate is relatively small 但亮温和地面降水强度之间的相关性较弱,这是由于该对流系统为倾斜的,冰相粒子和地面降水强度之间存在着位置上的不一致,并且观测角为倾斜的。
The mcc is composite of meso - , meso - and meso - scale convective systems which have different structure and motion features . although circularly approximately on the satellite imagery , the mcc shows linear distributions of radar echo , torrential rain , thunderstorm , cumulonimbus and mesoscale physical parameters as a squall line 它是中、和尺度对流系统组成的复合体,它在云图上近似圆形,其雷达回波、暴雨、雷暴、对流云、中尺度物理量场等却呈类似飑线的带状分布。
