Horizontal cross-section at 250 m altitude of reflectivity at 30 (contoured in grey) and 50 dBZ (contoured in dark grey) with 0–5 km average vertical vorticity contoured in magenta every  s−1 at (a) 0036 UTC and (b) 0045 UTC on 30 May 2004. Solid (dashed) contours denote positive (negative) values of average vertical vorticity.
