摘要

The Accelerated Climate Modeling for Energy (ACME) Project is a new and ongoing  DOE climate modeling effort to develop a high-resolution (0.250/L72 atmosphere, 0.10 ocean) earth system model targeted  specifically at next-generation DOE supercomputers to meet the science needs of  the nation and the mission needs of DOE. ACME is built on the Community Earth  System Model (CESM), but with three entirely new ESM components: MPAS-Ocean,  MPAS-SeaIce, and MPAS-LandIce. Its atmospheric model is developed from the  Community Atmospheric Model (CAM5.3) with notable changes to its physical  parameterizations and model resolution.

This  presentation will provide an update on the ACME model development. The mean  features of climate simulated by ACME fully coupled and uncoupled experiments  will be presented with the focus on its capability in simulating clouds,  radiation, and precipitation. Model sensitivity to both horizontal and vertical  resolutions and challenges and strategies in tuning high-resolution model at  current computational resources will be discussed.
