Short summary
This study evaluates the performance of the varying-resolution mesh model, E3SMv2-MPAS, in simulating key Arctic processes—from sea ice distribution and surface properties to the complex, three-dimensional structures of the Atlantic Water layer. We also pinpoint specific areas where the model still struggles, providing valuable directions for future model development. This progress means scientists can now use this tool more confidently to understand how Arctic ocean layers work and change.
This study evaluates the performance of the varying-resolution mesh model, E3SMv2-MPAS, in...
