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., 資料番号: SA4644715000}, pages = {129--135}, title = {Observation of Leonid meteor shower and middle/upper atmosphere with the MU radar in 1998-2001}, volume = {15}, year = {2003} }
