The annual EGU General Assembly meeting this year was held in Vienna from 27 April to 2 May. It welcomed 20,984 registered attendees, of which 18,646 made their way to Vienna from 120 countries and 2,338 joined online from 104 countries. Werner Bauer and Robert Piel attended and gave talks. In addition, Werner was the convenor of Session AS5.2 (Advances in Numerical Earth System Modeling: Identifying Systematic Errors and Charting Innovative Approaches to Enhance Numerical Weather and Climate Prediction). Robert gave a talk based on his PhD thesis on “An adaptive, structure-preserving numerical method for the rotating shallow water equations using hierarchical finite elements generated through subdivision“. An abstract is available (link here). Werner gave a talk on joint work with Colin Cotter (Imperial College) on “Fully implicit timestepping methods for the rotating shallow water equations”. An abstract is available (link here). The photo below shows Werner and Robert at the conference.
