Three-Dimensional Storm Structure and Low-Level Boundaries at Different Stages of Cyclic Mesocyclone Evolution in a High-Precipitation Tornadic Supercell

Figure 10

Horizontal cross-sections at 5 km altitude for the 0108 UTC analysis of vertical velocity (in m s⁻¹, according to the color scale), radar reflectivity greater than 20 dBZ (contoured every 10 dB with 20 dBZ dashed and higher values solid). Vertical vorticity maxima are annotated in magenta at −5 (dashed), 10, and 30 (solid) (10⁻³ s⁻¹).
