This work is from @JiliDong-NOAA and is identical to PR #225. The description for that PR is pasted below:
This PR follows Jongil's suggestion and aims to reduce the large convective reflectivity caused by saSAS adjustment in the first timestep during a warm start. The issue is likely related to the inconsistency when DA updates the moisture at t but not the moisture from the previous timestep (t-36s). The moisture from the previous timestep is needed for initializing sigmab (updraft area fraction) when calculating qadv (q advection or tendency term).
The PR forces qadv to zero in the first timestep when a namelist parameter sigmab_coldstart is set to .true. It also reduces the lower limit of sigmab from 0.01 to 0.0 in the first timestep.
