title: Spiral Cloud Band Associated with a Tornado.
abstract: The radarscope photographic sequence, by far the best example on record, reveals a spirally banded structure about 10 miles in diameter which is similar to spiral bands of hurricanes ranging as far as 250 miles and to the banded cloud structure of well-developed storms of 1000 miles as photographed by Tiros I.
