A method for extracting coherent vorticity sheets and current sheets out of three-dimensional homogeneous magnetohydrodynamic ͑MHD͒ turbulence is proposed, which is based on the orthogonal wavelet decomposition of the vorticity and current density fields. Thresholding the wavelet coefficients allows both fields to be split into coherent and incoherent parts. The fields to be analyzed are obtained by direct numerical simulation ͑DNS͒ of forced incompressible MHD turbulence without mean magneticdoi:10.1063/1.3195066 fatcat:kcnzhihxzjhgzokzm3hller6zq
