Multipion production in high energy nucleus-nucleus collisions is considered within the model of the pion radiation by classical current. Strong coherent effects of narrowing of the pion longitudinal and transverse momentum distributions are predicted at RHIC energies. The coherence enhances the large pseudorapidities, producing a bump in the distribution. The growth of the average pion multiplicity and oscillation effect in the multiplicity distribution are caused by the coherence as well.
