Visualization of the final shape and horizontal extent of the domain of elevated risk (DER) from two simulation realizations featuring (a) 10 deg and (b) 90 deg mean flow directions. The red contours represent the baseline DERs with $N_{b,\mathrm{cr}}=100$ while the cyan and white contours represent the decreased $N_{b,\mathrm{cr}}=50$ and increased $N_{b,\mathrm{cr}}=150$ to study the sensitivity of the DER size to $N_{b,\mathrm{cr}}$. Note that the white contours get a rosa appearance when seen through the transparent red contours. The contours are clipped at $z=3.15\mathrm{m}$.
