摘要: Abstract Some results of the first 10 cm dual-Doppler radar measurements in a tornadic storm are presented. A mesoscale, cyclonic circulation confirms proposed single Doppler vortex signature and indicates that curved reflectivity hook echo is around periphery circulation. The interpolated tornado position within mesocyclone where high-variance velocity spectra suggest strong gradients.
