Rytov number
Encyclopedia
The Rytov number is a fundamental scaling parameter for laser propagation through atmospheric turbulence
. Rytov numbers greater than 0.2 are generally considered to be strong scintillation
. A Rytov number of 0 would indicate no turbulence, thus no scintillation of the beam.
Turbulence
In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic and stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and time...
