ArWen 2.5.7

A default lid above the anvils, and a moving nest that resumes.

Fixed:

  • The default model top moves from 100 hPa to 50 hPa (p_top 5000 Pa, the
    WRF Registry default), taking the damp_opt=3 sponge base from ~11 km
    to ~15.6 km AGL. The 100 hPa lid damped anvil-layer updrafts and
    smeared convective structure on a bare default run; measured on a
    3 km HRRR A/B vs MRMS, the 50 hPa lid restores updraft tops and core
    counts at equal-or-better FSS and no VRAM or wall cost. Emissions are
    bounded per source: a source whose certified ladder stops at 100 hPa
    (GFS pgrb2, 20CRv3 NetCDF) keeps its covered top.
  • A tree with [relocation.containment] can be resumed: the checkpoint
    records the parent slides in the move chain, the slid parent is put
    back with its own initializer, and a restore is no longer judged by
    the per-move steering cap.
  • A resumed or branched run of a moving nest keeps the precipitation
    totals a move shifted into the domain edge; the restore migration
    zeroes only what no relocation carries.

The moving-nest restart fixes were contributed by Roch.
