We formulate and solve the complete initial value zonal flow problem by retaining the fully self-consistent axisymmetric spatial perturbations in the electric and magnetic fields.  Simple expressions for the electromagnetic test of the zonal flow residual in gyrokinetic codes.  Unlike the electrostatic potential, the parallel vector potential and the parallel magnetic field perturbations need not relax to flux functions for all possible initial conditions.</dcterms:description><dcterms:subject>Physics</dcterms:subject><dcterms:subject>electromagnetic perturbations</dcterms:subject><dcterms:subject>spatial perturbations</dcterms:subject><dcterms:subject>turbulence</dcterms:subject><dcterms:subject>zonal flow</dcterms:subject><dcterms:subject>zonal flow residual calculation</dcterms:subject><dcterms:date>2018-12-07</dcterms:date><dcterms:rights>This dataset is made available without information on how it can be used.
