Meteor trail and head echo observations during the Leonid shower periods have beencarried out using the middle and upper atmosphere (MU) radar, Shigaraki, Japan (35N, 136E) since1990 and 1998, respectively. In 1998, 1999 and 2001, peak activities of Leonid meteor showers wereobserved with the same observational set-up. Characteristics of the outburst in the three yearsare displayed. The wind velocity profiles between 80 and 100 km altitudes were simultaneouslydetermined with I km height and 30 minutes time resolutions with underdense meteor echoes.Significant local time variations in the orders of day-to-day, and year-to-year of the wind velocityproflle and wind shear are exhibited, as they would affect significantly the evolution of persistenttrain.
