A PROPOSAL OF TORNADO DETECTION METHOD USING WIND SENSING ON MOBILE PLATFORM

Abstract

  Local strong wind phenomena are becoming major concerns in risk management of transportation. Tornado detection by mobile platform sensing is studied for reduction of damage by emergent operational management, such as emergent braking. Rankine vortex is employed for theoretical modelling of tornados, and prediction method for maximum wind velocity and its occurrence time is constructed based on mathematical analysis of relative position of the mobile platform and tornado center. The method is also applied to measured wind velocity data during tornado, and its applicability is investigated.
