The statistical description of compressible turbulence in application to GMC are carried out. The initial supersonic turbulent spectrum evolution on the stage of shock wave formation is considered. It is found that interecting shock fronts lead to the flat filamentary structures formation in the supersonic turbulent medium. The clumps size distribution and space filling factor are determined. It is found that these functions depend on a physics of clump’s formation.
