英文简介The observation on thunderstorm in the northeastern of the Qinghai-Tibet Plateau will be conducted by using the multistation Receiving System of Lightning VHF Radiation Sources Power and synchronized 3-D Location System of Lightning VHF Radiation Pulses. The data of Sources Power Radiated by lightning discharge will be acquired. The spactial-temporal of evolution characteristics of lightning VHF radiation source powers will be determined at the different processes of lightning for every type of flash in plateau area with combination narrow interfermeter system and surface electric field change. The mechnism of lightning radiation sources power move and lightning initiation will be studied. The mechnism of positive and negative breakdown will also be discussed by inversion of the charge structure of lightning flash. The relation of radation sources power move of lighting discharge and Multi- parametric echo information will be discussied with combination of radar data. The used of the lighting radation sources power study the the process of lightning discharge transimission is a new method for field of lightning research. The research result will not only provide valuable information for lightning protection and warning of severe weather but also be helpful to explore the charge structure and its cause of formation.
