It is shown that the level of plasma turbulence strongly depends on a direction in the Galaxy. It is obtained that there are nearly three orders of magnitude larger in the directions of the central portions of the Galaxy at low latitudes IbI 10°. In the galactic arms the highest values of level of turbulence are near supernova remnants located in the regions with large electron densities. We show that the typical radius of the strong turbulence region around supernova remnants is ≅ 35 pc. Within this region the level of plasma turbulence is approximately 10 times larger, than on its edges. It is concluded that presence of supernova explosions in the medium with large density is necessary for existence of strong turbulence in interstellar plasma.
