For the statistical study of scintillation fading of 100GHz band, the propagation experiment has been carried out through the 390m path in Nagoya from April 1988 to March 1991. In this paper, statistical analysis for the origin of the scintillation fading in the short range path has been discussed. Large scale scintillation fadings where the receiving power changes before and after the scintillation fadings are clearly attributable to the difference of the water vapour densities due to the difference of the wind directions. Other scintillation fadings are more or less caused by southern wind and there are many scintillation fadings when water vapour densities are of 7-21g/m^2 before and after the scintillation fadings.
