Evidence from volcanology studies indicates that the entrainment of surrounding atmospheric gases and air into volcanic ash plumes is driven by turbulent mixing and convective plume dynamics.
The claim states that entrainment of atmospheric gases into volcanic ash plumes is driven by turbulent mixing. Papers [0] and [5] directly support this mechanism, detailing how turbulent mixing and dynamics govern air entrainment in volcanic plumes and jet structures. No papers refute this claim.
