Abstract : Several cases of GOES digital infrared data and Doppler Sounder array data during the three-hour time period immediately preceeding the touchdown of the tornado were analyzed. Tornado-associated clouds are compared with non-tornado-associated clouds using satellite infrared data, ray tracing of gravity waves detected by the Doppler Sounder array and rawinsonde data. The satellite observations are at 15-minute intervals. Our study shows that tornado-associated clouds are always accompanied by overshooting turrets penetrating above the tropopause. The growth rate of the storm-associated clouds is much greater than that of non-severe storm-associated clouds. (Author)
