E3SM in Recent PAN-GASS Meeting
The Global Energy and Water cycle Exchanges (GEWEX) Global Atmospheric System Studies Panel (GASS) held its 3rd Pan-GASS Meeting, Understanding and Modeling Atmospheric Processes (UMAP 2022), at the Hyatt Regency Hotel in Monterey, CA, USA, from 25–29 July 2022.
UMAP 2022 aimed to bring together weather and climate scientists, including both observationalists and modelers, to discuss the key issues of atmospheric science. The program included all aspects and methods of model development from deterministic numerics to stochastic forcing; process modeling to parametrization; observational constraints to diagnostic techniques; and idealized modeling to operational forecasting and climate predictions. The purpose of the conference was to discuss progress in understanding atmospheric processes and representing them in models, coordinate current initiatives, and make plans for the future.
UMAP 2022 was organized around four main themes:
- Organization of shallow and deep convection
- Surface-atmosphere interactions and the boundary layer
- Cloud systems and associated processes (microphysics, physics, dynamics, radiation)
- Towards global km-scale modeling and Digital Twins of the Earth System
The E3SM project and E3SM model were highlighted and well represented within the Pan-GASS meeting. Shaocheng Xie, the Lead of the Atmospheric Physics Next Generation Development (NGD) subproject within E3SM, served as one of the chairs, and many E3SM members presented their E3SM-related work at the meeting.
Future activities conducted by the GEWEX GASS panel will emphasize answering the following overarching questions:
- What is the role of microphysical and mesoscale atmospheric processes in Global Water and Energy Exchanges?
- What controls cloud phase and precipitation?
- What controls Mesoscale Organization?
Global storm-resolving models, process modeling, satellite data, and detailed field observations are critical to support GASS future research activities. Smaller annual meetings will be organized in the next few years, focusing on specific topics/projects, and the next Pan-GASS meeting will be organized in 3 to 4 years.
