The turbulent dissipation is the dominant mechanism of dissipation of waves with wavelengths in the range from hunderds of AUs to hundreds of parsecs, propagating in the interstellar medium. As such, it is critically important for understanding the development of linear instabilities in the ISM and intergalactic medium, e.g. Cosmic Ray (CR) streaming instability or CR anisotropy instabilities. Furtermore, the measurement of the dissipation rate is a useful tool to study the turbulence itself. We present the model of nonlinear decay of a weak wave in a three-dimensional incompressive MHD turbulence which gives a different decay rate for parallel and perpendicularly-directed waves, and provide the decay rates for arbitrarily directed waves. We also present the results of the direct numerical simulations of wave decay.
