The reduced magnetohydrodynamic equations governing low-frequency elec
tromagnetic turbulence are derived taking into account the compression
al and sheared magnetic field perturbations in high-beta magnetoplasma
s. The present model equations should be basic for studies of turbulen
ce properties and coherent vortex structures involving Alfven waves th
at have been frequently observed at the magnetopause.
