Dr. Harrington's current research focuses on Arctic clouds and their unique behavior. Over the past five years, he has mainly focused on stratus clouds over the solid Arctic ice pack and over the marginal ice zones (transition regions between solid ice and open ocean) using the RAMS model. Jerry's modeling studies of these clouds have shown a surprising  sensitivity between ice nucleation and cloud longevity over the Arctic. In addition, Jerry's modeling studies suggest that alterations in cloud microstructure over the Arctic may feed back significantly to the larger scale.
