Abstract
Charney in 1971 generalized results for two-dimensional (2D) turbulence to quasigeostrophic (QG) turbulence and obtained two results that have importa nt implications for the atmosphere. The first is an attempt to prove that, similar to 2D turbulence, energy in QG turbulence goes only upscale in the net. The second is a demonstration that 3D QG motion in terms of a 3D waven umber in a stretched coordinate is isomorphic to 2D turbulence. Charney's p roofs are shown here to be problematic.
