UNIQUE DAMAGE PATTERNS CAUSED BY A TORNADO IN DENSE WOODLANDS.

Abstract

Storm damage inflicted by a tornado on an area in Pennsylvania was photographed from the air. Drawings made of these photographs represent the types of damage patterns caused by the tornado. The damage patterns derived from the fallen trees indicate convergence towards a line along the propagation of the tornado and rotation of winds. Combining these two wind-field characteristics gives a picture of the tornado as a very strong updraft surrounded by spiraling convergent winds. (Author)
