WebMar 1, 2012 · The BRN shear value is the denominator of the bulk Richardson number equation and is representative of the difference between a density-weighted mean wind speed taken over the lowest 6 km of the profile and an average near-surface wind speed taken over the lowest 500 m of the profile; that is, WebNov 2, 2016 · The average BRN shear value was 106.4 m 2 s 2, whereas the most tornadic TCs had values ranging between 80 and 220 m 2 s 2. This is important because BRN shear values at or above 40 m 2 s 2 support environments more conducive for TC-induced tornadogenesis . Looking at effective bulk shear, the average value was calculated to be …
