SUMMARY:Towards Kilometer-Scale Global Storm-Resolving Weather and Climate
  Simulations, Part II
DESCRIPTION:Minisymposium\n\nThe predictive skill of weather and climate m
 odels has significantly improved over the past few decades, thanks to a hu
 ge increase in resolution facilitated by increased supercomputing capacity
 . A million-fold increase in computational power has allowed the resolutio
 n of operational global weather models to increase from 500 km to 10 km si
 nce 1980, for example. Further increases towards 1 km resolution would del
 iver significant improvements in the skill of weather and climate simulati
 ons. However, these simulations are still not viable for operational predi
 ctions due to the vast increase in computational cost. The computational s
 peed of global kilometer-scale simulations on today’s supercomputers is be
 low a practical level by at least two orders of magnitude. Furthermore, ta
 king advantage of future exascale supercomputers with heterogeneous archit
 ectures will require a substantial rethink of traditional coding paradigms
 . This two-part minisymposium will bring together researchers on global ki
 lometer-scale atmosphere and ocean models from around the world. Speakers 
 will discuss both the scientific and computational challenges of 1 km reso
 lution. They will present the state-of-the-art of their respective simulat
 ion systems and their roadmaps for the future. The challenge of kilometer-
 scale global simulations can be met, but only by the synthesis of ideas ac
 ross Earth-System science and supercomputing.\n\nTowards Global Cloud-Reso
 lving Climate Modeling with X-SHiELD\n\nHarris\n\nWe discuss development o
 f the eXperimental System for High-resolution prediction on Earth-to-Local
  Domains (X-SHiELD) for global cloud-resolving simulation. We discuss the 
 challenges we had in stabilizing and tuning X-SHiELD, and how we overcame 
 them. Results from both the 40-day DYAMOND Phase 2 sim...\n\n-------------
