RECORDED PRESSURE DISTRIBUTION IN THE OUTER PORTION OF A TORNADO VORTEX

Abstract
Records are presented from nine barographs located in a small area close to the path of a tornado. The pressure profile in the range from 720 to 2,300 feet from the path of the tornado center as determined from the barograph records was found to be in good agreement with calculations based on a simple model consisting of a frictionless vortex with in-flow.
