We are pleased to announce that abstract submission to the workshop on Physics Dynamics Coupling in Weather and Climate Models, to be held on September 20-22, 2016 in Richland, WA, USA at the Pacific Northwest National Laboratory, is now open. The PDC16 workshop has a strong emphasis on the mathematical and computational aspects of weather and climate modeling. It aims at addressing challenges in the development of advanced algorithms to accurately and efficiently represent process interactions that determine fundamental characteristics of weather and climate systems.
