The radar image gallery contains radar pictures of severe weather including tropical cyclones , rainstorms , hailstorms and thunderstorms . there are also pictures containing artifacts caused by special conditions in the atmosphere and by the way the radar is operated . these pictures are included in the gallery to remind the reader the importance of interpreting radar pictures with caution 图像廊搜罗了在恶劣天气下所拍摄到的雷达图像，如热带气旋、暴雨、雹暴及雷暴。此外，一些在特别的大气状态下或由于雷达本身的运作特性所引致的假降雨现象，都会包括在图像廊内，让读者在诠释雷达图像时多加留意。
Neither party shall be held responsible for failure or delay to perform all or any part of this contract due to flood , fire , earthquake , snowstorm , drought , hailstorm , hurricane , or any other events that are beyond the control of the affected party and could not reasonably be expected at the time of conclusion of this contract or have been avoided or overcome by such party 合同当事人一方因洪水、火灾、地震、暴风雪、旱灾、冰雹、飓风或其他该方当事人无法控制，并在签订本合同时不能合理预见、无法避免或无法克服的事件造成其无法履行或迟延履行全部或部分合同义务，则该合同当事人应免责。
Using the 1ap 3 - d hailstorm numerical model , we analyze influence of variation on rainfall amount , hail fallout amount , dynamical process of cloud , microphysical process , mechanism of hail suppression with seeding , and seeding outcome . besides , we use those study outcomes and bring forward some advice about using and improving model . we simulate a hailstorm occurred in nanjing county and analyze influence of raindrop , ice crystal , graupel size distribution on outcome of model 本文利用中国科学院大气物理研究所的三维冰雹云催化数值模式，通过对冰雹云的模拟和对谱参数的数值试验结果，分析了冰雹云中粒子谱形的变化，对云和降水过程的影响，其中包括雨滴谱、冰晶谱、霰谱的形状参数对自然云的发展过程、降雨降雹、云中微物理过程、霰以及冰雹的形成机制的影响。
