Summary
👤
Senior🎓
Top SchoolJohannes Röhrs is a research scientist and operational leader with 11 years of experience advancing ocean and sea ice prediction at the Norwegian Meteorological Institute, now serving as Head of Division for Ocean and Ice. His work blends numerical modeling, 4D-var data assimilation, trajectory modeling and field campaigns to improve forecasts of surface currents, oil spill dispersion and marine ecosystem transport. He holds a PhD in oceanography and a Diplom in meteorology, and has led projects ranging from coastal assimilation systems to wave–ocean coupling and individual-based plankton models. Johannes combines hands-on model development and verification with program-level management, steering Arctic remote sensing and forecasting collaborations. Colleagues rely on him for translating complex physical processes—boundary layer dynamics, particle transport and sea-ice physics—into operational, decision-relevant tools. A practical innovator, he often bridges theory and application by deploying models directly in forecasting pipelines and fieldwork.
