| 内容記述 | The local and nonlocal characteristics of triad enstrophy transfer in the enstrophy inertial range of generalized two-dimensional turbulence, so-called α turbulence, are investigated using direct numerical simulations, with a special emphasis on α=1, 2, and 3. The enstrophy transfer via nonlocal triad interactions dominates the transfer dynamics in the enstrophy inertial range, irrespective of α. However, the contributions from more local interactions to the total enstrophy transfer increase as α decreases. The results are discussed in connection with the local and nonlocal transition of the enstrophy transfer at α=2 expected from the phenomenological scaling theory. The specific nature of the enstrophy transfer in surface quasigeostrophic turbulence (α=1) is also discussed. | |||||||||
