Abstract
Significant water conservation errors were found in both the atmosphere-only and the coupled model simulations with the ne30L72 ACME v1.0_alpha7 model. Water conservation errors at different model resolutions (ne11L72, ne16L72, ne30L72, and ne120L72) are investigated. For the atmosphere component, we have identified several error sources, which include:
...
The error magnitude from individual sources changes with the model horizontal resolution. Solutions are found to eliminate the water conservation error from sources (1-4). By using an alternative physics-dynamics coupling method, the water conservation error in the ne30L72 atmosphere model decreases by ~50 times. The error can be further reduced by one order of magnitude if two new fixers for error sources (3-4) are used. Future work needs to done for reducing the internal water and energy conservation errors in individual processes/parameterizations.Water conservation errors in recent (alpha 8+) AMIP and coupled simulations will also be discussed.
