Abstract

The wavelet analysis is performed on the numerical results of two-dimensional magnetohy-drodynamic (MHD) turbulence. By virtue of simultaneous resolution in scale and position of wavelet decomposition, the intermittent nature is well captured. The whole region is successfully divided into the two regions with different inertial subranges of energy spectra: the turbulent region with Et(K) ∝ K-3/2 and the coherent region with ET(K) ∝ K-2. The local energy transfers by convection of velocity field and by stretching of magnetic field are probably responsible for the transition of turbulent state into coherent state.
