Storm tracks on the Nullarbor Plain

Abstract. Infrared images obtained from instruments on environmental satellites have revealed long straight lines across the Nullarbor Plain in southern Australia. These features, which are up to 400km long and 10 to 20km wide, are not normally visible in satellite sensor imagery, but were observed for several days in October 1992. Subsequent investigations have shown the tracks to be caused by increased soil moisture following the passage of localised storms across the area.
