The snow weather process in Jiaocheng County in early February, 2014 was analyzed based on conven-tional meteorological data. The results showed that the snow was affected by low vortex with shear and short wave trough.The shear and low-level jet brought enough moisture for the snow. The low-level jet and strong vertical as-cending motion provided beneficial con-dition for the formation of the snow.
