4-6-km Storm Relative Winds (kts)

Mid-Level SR (Storm Relative) winds (4-6-km) are of some use in discriminating between tornadic and non-tornadic supercells. Tornadic supercells tend to have 4-6-km SR wind speeds in excess of 15 knots, while non-tornadic supercells tend to have weaker mid-level storm-relative winds.
