A New Hypothesis for Layers of High Reflectivity Seen in MST Radar   Observations
  Analysis of MST radar observations at Gadanki (near Tirupati, India), for a period of 14 months from 1995 September to 1996 November, shows that "Clear air Turbulence" is not the primary source of high MST radar reflectivity; this conventional idea needs to be modified. An alternative hypothesis based on the microphysics and microdynamics associated with aerosols and water substance in the atmosphere, is presented here.
