The numerical simulation for the pearl river networks in the area of guangzhou is calculated by ecomsed model that is based on the observed data for typhoon no . 9316 in storm surge of the flood season of 1999 摘要利用1999年洪季和9316号台风风暴潮的实测资料，通过ecomsed数学模型对珠江河网广州区域进行数值模拟计算。
The potential vorticity ( pv ) on isobaric and isentropic surface was studied . furthermore , the pv structure of another rainstorm caused by the 9711 typhoon was compared with it and the difference of the two rainstorm was discussed 另外又与1997年第11号台风登陆北上造成山东全省大到暴雨过程的位涡场结构进行了对比分析，讨论了两次暴雨过程位涡场结构的异同。
News released by shenzhen observatory at 5 : 00 pm yesterday said that the 13th typhoon , “ dujuan ” has passed the bashi strait yesterday afternoon and reached to northeast sea of nanhai ; it is approaching to coast of guangdong province 据深圳市气象台昨天下午5时发布的消息,今年13号台风“杜鹃”于昨日下午穿过巴士海峡,于今日凌晨2时进入南海东北部海面,并逐渐靠近广东沿海。
A severe rainstorm over liaoning occurring from august 19th to 21st in 1997 by a landing northward tropical cyclone ( 9711 ) was simulated by mm5 non - hydrostatic model . through comparing the simulate results with the real weather , the different layer synoptic - scale circulation , height field , temperature field and precipitation were successfully reappeared . the main synoptic background in the case was as follow 使用psu ncarmm5v3非静力模式，对1997年登陆北上的11号台风， 8月20日夜间在辽宁登陆前后，给辽宁带来的大范围大暴雨进行了数值模拟，并通过模拟的高、中、低空形势场(高度场、温度场) ，降雨量以及降雨强度与实况进行对比分析，是一次比较成功模拟，基本再现了辽宁大暴雨过程物理量场变化的全貌。
The field observation of the sediments of storm surge produced by no . 11 typhoon in 1997 shows that sedimentation rate of storm surge sediments are greater than that of normal astronomical tide sediments , and the grain size shows relative coarse with poor sorting . vertical sequences of the storm sediment show parallel bedding and overlapped by hummock bedding . these characteristics provide good basis for building the index of storm surge deposit 通过对梁垛河闸9711号台风的现场观测并结合目前已有的风暴潮沉积的研究，分析了风暴潮沉积在构造和结构上的特点，从而建立了正常潮滩沉积中风暴潮沉积的识别标志，同时在野外观测中还发现即使在风暴潮期间，高潮滩上部仍存在只有淤积没有侵蚀的地带。
