The University of Oklahoma’s School of Meteorology and the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) will host the workshop. Presentations will cover polar predictability from weather to interannual time scales; sea-ice dynamics and prediction; impact of the Arctic on lower latitudes; operational and research efforts; and end user needs and capacity of the scientific community to address them.
