This　paper　makes　a　research　on　the　broadband　velocity　records　of　the　total　process　of　typhoon　formation　and　development　obtained　by　Seismic　Monitoring　Network　of　Fujian　Province,　presents　a　root-mean-square　velocity　abstracted　from　moving　time　window　technique　as　a　measure　of　characteristic　energy,　studies　viberation　energy　changes　of　typhoon　development　process　from　start　to　end　and　gets　a　corresponding　statistical　relation　between　root-mean-square　velocity　and　typhoon　parameters.　The　research　result　preliminary　shows　that　the　data　of　seismic　monitoring　network　can　be　applied　to　monitoring　and　prediction　of　typhoon.
