Most range from 0.3 to 0.5 mm (0.012 to 0.020 in) in length, although the largest species may reach 1.2 mm (0.047 in). These grains of sand, up to about 0.5 mm (0.020 in) in diameter are jerked into the air but soon fall back to earth, ejecting other particles in the process. Such electric fields, which range in size up to 80 kV/m, can produce sparks and cause interference with telecommunications equipment. They tend to grow vertically; they can reach a height of 500 m (1,600 ft), making them the tallest type of dune.
