WebNov 24, 2024 · 2.3 Bulk Richardson number method In the spirit of a like-for-like comparison, the BLHs derived from radiosonde and reanalysis data (MERRA-2, JRA-55, and NCEP-2) are calculated using the bulk Richardson number (BRN), which also serves as the built-in algorithm in ERA5 for BLH products.
WebBulk Richardson Number Shear (m 2 s-2). The BRN (Bulk Richardson Number) shear is similar to the BL-6-km shear, except that the BRN Shear uses a difference between the low-level wind and a density-weighted mean wind through the mid-levels.Values of 35-40 m 2 s-2 or greater have been associated with supercells. 2 s-2 or greater have been associated … WebThe Bulk Richardson Number is * ML50 CAPE = conservative estimate of CAPE, lifting an average parcel in the bottom 50 hPa of a sounding. This value can be found via …
In thermal convection problems, Richardson number represents the importance of natural convection relative to the forced convection. The Richardson number in this context is defined as where g is the gravitational acceleration, is the thermal expansion coefficient, Thot is the hot wall temperature, Tref is the reference temperature, L is the characteristic length, and V is the characteristic velocity.
