Hello all,

When runing WRF V 4.3.3 with afwa_severe_opt = 1
the hail field AFWA_HAIL is always empty (all values are set to 0) even with weather situation with severe weather
Any suggestion to fix this issue


Here is my namelist.input

Your namelist.inout indicates that you run with mp_physics = 8. Note that this option doesn't output hail information.
Can you switch to mp_phsyics =7 or 9, then try again?
