Summary

  • I think the best fields for locking the physical atmosphere of Jnr to that of Snr are
    • Stash 2: U COMPNT OF WIND AFTER TIMESTEP
    • Stash 3: V COMPNT OF WIND AFTER TIMESTEP
    • Stash 9 (JULES): SOIL MOISTURE CONTENT IN A LAYER
    • Stash 20 (JULES): DEEP SOIL TEMP AFTER TIMESTEP
    • Stash 214 (JULES): UNFROZEN SOIL MOISTURE FRAC AFTER TS
    • Stash 215 (JULES): FROZEN SOIL MOISTURE FRAC AFTER TS
    • Stash 255: EXNER PRESSURE (RHO) AFTER TIMESTEP. This makes EXNER a bit worse, but big improvements for W and ETADOT.
    • Stash 388: THETAVD AFTER TIMESTEP
    • Stash 391: VAPOUR MIXING RATIO (mv) AFTER TS
    • Stash 392: CLD LIQ MIXING RATIO (mcl) AFTER TS
    • Stash 393: CLD ICE MIXING RATIO (mcf) AFTER TS
    • Stash 394: RAIN MIXING RATIO (mr) AFTER TS
    • Stash 398: EXNER SURF AFTER TIMESTEP
  • Energy budget is a worry and needs looking into.
  • Increasing Jnr's timestep from 20 mins to 30 mins, significantly degrades the locking for W and Dη/Dt.
