WRF v4.1 vs 3.9.1.1 is slow due to additional dbz computations #939

Open davegill opened 5 years ago

WRF 4.1. vs 3.9.1.1 is slow due to computing the dbz at each time step (with several MP schemes). The solve_em.F file has:

IF (config_flags%nwp_diagnostics == 1) diag_flag = .true.

... and that kicks off the dbz computation.

This was added Jan 11 2019 with: commit: 86f767535 PR: make refl_10cm available if nwp_diagnostics is on (#749)

Can you quantify "slow"? If nwp_diagnostics is on and do_radar_ref is off, does it avoid this problem or cause others? Jimy
