• An exact solution associated with a stationary Gaussian distribution is obtainedfor two-dimensional ideal incompressible magnetohydrodynamic turbulence byusing the Wiener-Hermite expansion with a time-dependent ideal random func-tion.Thesr>ectraareujveribv<$(;:z)<6(v:r)>ccv-'J(u-I-v)and<.4(u:r).4(v:r)>oc(v'-F->')-'J(u-l-v) where cfi and A are the Fourier traxtsforms of the stream func-tion and the electro-magnetic poten?tial respectively. A remarkable result is thatthe two-time correlation function (/(A: t)A(pc 0)>=0 for an arbitrary t, but thisdoes not necessarily mean the statistica]Jy independeztce of 4 and A.
