A Theory of Long-Duration Meteor-Echoes Based on Atomospheric Turbulence with Experimental Confirmation

摘要

A theory of long-duration meteor-echoes is developed, based on the assumption that a meteor-trail is rendered rough by the action of the small eddies in the atmosphere. This theory leads to the conclusion that, if loss of electrons from the trail by recombination and/or attachment is neglected, the field-strength of a long-dura¬tion meteor-echo in its decay-phase should be inversely proportional to the cube of time subsequent to formation of the trail.
