![]() (a) Swirl velocity (solid contours) together with highest levels of total velocity variance (dashed, contour level is 0.2), (b) angular momentum, (c) depleted angular momentum streamfunction. ![]() Normalized, axisymmetric, time-averaged contours in the radial–vertical plane for the corner flow region of a sample low-swirl tornado vortex. The dashed contour indicates a normalized vertical velocity level of −0.2. 1 at a height of 0.2 r c, showing perturbation pressure (solid contours in units of ρ V 2 c) and normalized vertical velocity (grayscale). Instantaneous horizontal cross section of simulated tornado from Fig. ![]() (a) Swirl velocity (solid contours) together with highest levels of total velocity variance (dashed, contour level is 0.1), (b) magnitude of the velocity vector in the r–z plane, (c) perturbation pressure, (d) angular momentum, (e) streamfunction, (f) depleted angular momentum streamfunction. Normalized, axisymmetric, time-averaged contours in the radial–vertical plane for the corner flow region of a sample high-swirl tornado vortex. ![]()
