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

Figure 14

Near-surface boundaries are outlined in solid colors: red is the primary RFGF, green is the FFCB, light blue is the SRFGF, and dark blue is the new SRFGF. The near-surface mesocyclones are indicated in black ovals; the midlevel updraft shear region vorticity is indicated by purple ovals. Reflectivity was shaded grey at 40 and dark gray at 50 dBZ, and downdraft stronger than -5 m s⁻¹ at an altitude of 2 km is shaded in yellow.
