DESCRIPTION:Lightning strikes generate very low frequency pulse of electro
 magnetic radiation that propagate around the world with the earth’s surf
 ace and the ionosphere acting as a waveguide. The Met Office has a global 
 network or receivers to detect these pulses and calculate the location of 
 the strike. We are currently part way through project to replace this netw
 ork\, and need to model the pulse propagation in order to optimise the sys
 tem design and improve the location accuracy. We have models that solve Ma
 xwell’s equations using analytic and finite-difference methods to descri
 be different aspects of the physical system. The project is to further dev
 elop these models to study the sensitivity of the propagation to different
  physical conditions.\n
