Abstract
For an aircraft flying at height the far vortex wake represents two parallel, sinking, oppositely rotating vortex tubes. The loss of circulation of each of the vortex tubes with time is caused by interpenetration (diffusion) between vorticities of opposite signs. When flying in a turbulent atmosphere the diffusion is intensified by elevated turbulence, which further decreases the circulation of each tube. Various empirical formulas are available presently for assessing the loss of circulation at low and high levels of atmospheric turbulence [11, 46, 63].
