Tornadoes

AVAILABLE WHILE QUANTITIES LAST

With winds that can reach speeds of three hundred miles an hour and funnel clouds that can measure a mile in diameter, tornadoes leave enormous damage in their wake. Now award-winning author Seymour Simon examines these twisting columns of air and destruction. With the clear, concise style he is noted for, Simon explains how tornadoes are formed, why and when they are most likely to occur, how scientists classify and track them – and what to do if one touches down. Spectacular full-color photographs show this powerful phenomenon in action.
