This paper described a lightning warning system(LWS) which can measure electric field intensity on the ground level by a planar-shutter type electric field mill(EFM). The prototype LWS measures electric field up to 20 ㎸/m with the sensitivity of 0.15 V/㎸/m. From the experimental result, the LWS provides data on the movements of thunderclouds and the possibility of lightning return stroke.
