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.
