UKESM-fast for UKESM-CN
Colin wants to apply UKESM-fast ideas to UKESM-CN N96 ORCA1
- Increase Δt: 20 -> 30 mins
- Increase radiation timestep: 1hr -> 3hrs
- Increase GLOMAP timestep: 1hr -> 3hrs
- Reduce vertical levels 85 -> 38 (same as used for HadGEM2-ES)
- Colin hopes speed: 6 -> 20 model years/day
