| 摘 要： | 为了加强重大暴雨过程的快速评估工作,利用逐日降水资料对吉林省1951～2004年明显暴雨过程特征进行了分析,建立了反映明显暴雨过程程度的3项单项指标及综合评估指数,在此基础上对明显暴雨过程的评估等级进行了划分.利用综合评估指数序列的峰度系数和偏度系数对综合评估指数进行了正态性检验.由于综合评估指数符合正态分布,给出了其异常气候重现期评估指标.利用明显暴雨过程的评估等级指标以及异常气候重现期评估指标对2005～2006年的明显暴雨过程进行了评估.结果表明,该方法实用可行,可以满足快速、及时评估等气象服务的需求.

| Abstract: | The significance of designing a new real time meteorological radar monitor system is discussed, and the design of the new type real time monitoring system of meteorological radar based on the wideband network technology is introduced. The structure mode and functions of this new system are described, and the feasibility of this design based on the wide band communication system is studied by discussing the TCP/IP and calculating the information quantity of meteorological radar data and the occupied bandwidth. The characteristics of the structure and storage of the real time monitoring information from CINRAD/SA meteorological radar are analyzed, and the monitoring, receiving, sending, and storing methods of meteorological radar information are introduced. The emphasis is put on the programming of software for information transmitting and storing. According to two basic protocols of the TCP/IP (TCP & UDP) and ADO data base programming technology, the long distance control of the operation of the meteorological radar can be realized in real time based on the existing wide band technology. |
