Profiling the turbulent atmosphere and novel correction techniques for imaging and photometry in astronomy [PDF]
, 2010 The turbulent atmosphere has two detrimental effects in astronomy. The phase aberration induced by the turbulence broaden the point spread function (PSF) and limits the resolution for imaging.

THE POINT OBJECT'S IMAGE FORMING RAY MODEL
Odessa Astronomical Publications, 2017 Light wave front's distortions are commonly explained by atmosphere turbulence. But Anler equation solution's analysis shows that distributed homogeneous medium even in the absence of turbulence makes nonlinear transformation of coordinates as well as ...

Vanishing enstrophy dissipation in two-dimensional Navier--Stokes turbulence in the inviscid limit [PDF]
, 2006 Batchelor (Phys. Fluids, vol. 12, 1969, p. 233) developed a theory of two-dimensional turbulence based on the assumption that the dissipation of enstrophy (mean-square vorticity) tends to a finite non-zero constant in the limit of infinite Reynolds ...
