Design and Implementation of VPDN-based 3G Wireless Meteorological Information Transmission System

[Objective] This study was to construct VPDN-based 3G wireless meteorological information transmission system, in order to achieve the backup transmission of real-time meteorological services in all levels of meteorological stations. [Method] The current situations and business requirements of municipal meteorological networks are analyzed, putting forward the idea of backup routes that using VPDN-based 3G wireless meteorological information transmission system as the ground transmission line. And the network structure, operation mode and the system implementation are described in detail. [Result] VPDN-based 3G wireless meteorological information transmission system realizes the backup of ground line. Compared with the Modem dial-up, it is more stable and with faster transferring speed. With the rapid development of communication technology and computer technology, the information transmission system will be more efficient and stable, and will play a greater role in meteorological information transmission. [Conclusion] With the continuous development of modern meteorology, various types of meteorological data increase, presenting higher demand for the meteorological information transmission system. The established VPND-based 3G wireless meteorological information transmission system of this study provides a solution for backup transmission of real-time meteorological services.

Transmission of Meteorological Information to a Cockpit and Application of ADS-B

Unpredictable meteorological information, especially that endangers flight safety, should be transmitted to a cockpit to make a flight crew obtain meteorological early warning that affects flight safety as soon as possible and adopt countermeasures, thereby avoiding the occurrence of flight safety accidents. At present, there are limited ways of transmitting meteorological information to a cockpit, and the application of Automatic Dependent Surveillance-Broadcast （ADS-B） is a new way of transmitting meteorological information to a cockpit.

Design and Realization of Meteorological Service and Meteorological Information Officer Management Business Platform Based on WebGIS Information Interaction

A meteorological service and meteorological information officer management business platform based on WebGIS information interaction is designed and realized.Firstly,the goals of system construction are introduced,and then the features of the system is analyzed.Finally,the subsystems of the system are studied,such as geographic information subsystem,information officer management subsystem,information release subsystem,information feedback and evaluation subsystem,radar analysis subsystem,time traceback subsystem,integrated display subsystem,etc.

Development and Application of Meteorological Disaster Monitoring and Early Warning Platform for Characteristic Agriculture in Huzhou City Based on GIS

Based on the needs of characteristic agricultural production for meteorological services in Huzhou City,we use C# programming language to develop the meteorological disaster monitoring and early warning platform for characteristic agriculture in Huzhou City. This platform integrates the functions of meteorological and agricultural information monitoring,disaster identification and early warning,fine weather forecast product display,and data query and management,which effectively enhances the capacity of meteorological disaster monitoring and early warning for characteristic agriculture in Huzhou City,and provides strong technical support for the meteorological and agricultural departments in the agricultural meteorological services.

Synergistic Integration of Detailed Meteorological and Community Information for Evacuation from Weather-Related Disasters: Proposal of a ‘‘Disaster Response Switch’’

Meteorological information used for disaster prevention has developed rapidly in terms of both type and specificity.The latest forecasting models can predict weather with very high resolutions that can characterize disaster risk at the local level.However,this development can lead to an overdependency on the information and a wait-and-see attitude by the public.At the same time,residents share and use various types of information for disaster response,such as local conditions,in addition to official disaster information.Our research in Japan verified the practicality and efficiency of synergistically integrating these types of information by examining actual evacuation cases.The current numerical forecasting models sufficiently identify locality from the viewpoint of various administrative scales such as prefectures,municipalities,and school districts,but the improvements to these models have failed to improve residents’judgment in successful evacuation cases.We therefore analyzed the relationship between meteorological information and residents’disaster response and confirmed that they were strongly correlated and were contributing factors in preventing disasters.We revealed differences between a community’s disaster prevention culture and the disaster information provided.This led us to propose a new concept in community disaster prevention that we call the‘‘disaster response switch,’’which can serve as a data-driven risk management tool for communities when used in combination with advanced meteorological disaster information.
