Parameterizations with the NCAR Single Column
Mixed-phase stratus clouds are ubiquitous in the Arctic and play an important role in climate in this region. However, climate models have generally proven unsuccessful at simulating the partitioning of condensed water into liquid droplets and ice crystals in these Arctic clouds, which affect modele...

Mixed-phase stratus clouds are ubiquitous in the Arctic and play an important role in climate in this region.
