SIAG-MPE

SIAM Activity Group on Mathematics of Planet Earth

SIAG/MPE is for mathematicians and computational scientists who care about the future of our planet. We are a multidisciplinary activity group studying Earth’s climate system and the effects of climate change; issues of resilience, sustainability, and biodiversity; and the impact of human activities on the environment. All activities organized by the group will be announced here. Stay tuned!

Announcements

We are pleased to announce the next Community Meeting for the SIAM activity group Mathematics of Planet Earth (MPE).

It will be a Colloquium on “AI-driven Climate Modeling: Present and Future” by Dr. Chris Bretherton, Allen Institute for Artificial Intelligence (AI2), USA. It will occur on Thursday, November 21, 2024, at 11:00 a.m. EDT (23:00 CST-HK, 17.00 CEST, 15:00 UTC, 8:00 a.m. PDT). Please save the date!

The Zoom link for the SIAM MPE Community Meeting is https://siam.zoom.us/meeting/register/tZEsc-uqqT8rHtP9zP1L2qlJChWvXikAQngh.

The abstract of the Colloquium is provided below, along with all Zoom details. The meetings are recorded (see SIAM MPE Community Meetings - YouTube).

Abstract:

AI-driven weather forecast models are now more accurate than the best physics-based models. Using similar technology, the open-source Ai2 Climate Emulator (ACE) has been trained to accurately emulate both the daily weather variability (including rainfall extremes) and climate of two leading global atmospheric models, at 100-1000x smaller computational cost. Unlike reanalysis-trained AI weather forecast models, ACE is designed to be trained and deployed across multiple climates; for this purpose, it can be coupled to a simple ‘slab ocean’ model. In the near future, ACE coupled to a companion emulator of a full-physics ocean will affordably emulate hyper-realistic but hyper-expensive ‘digital twin’ models of the atmosphere and ocean with km-scale grids. Digital twin models avoid key uncertainties in present-day coarser-grid climate models and may help us more reliably predict regional trends in precipitation and other climate extremes. The combination of ACE and digital twins promises to provide more reliable local information for climate-sensitive decision making without the complexity of dynamical downscaling.

Short bio: Chris Bretherton directs a climate modeling group at the Allen Institute for AI (Ai2) in Seattle which uses machine learning trained on global storm-resolving model output and observational data to improve climate model simulations. He is an Emeritus Professor of the Atmospheric Science and Applied Mathematics Departments at the University of Washington, where for 35 years he studied cloud formation and turbulence and improved their simulation in atmospheric models. He is an American Meteorological Society Charney Award winner, IPCC author, AMS, and AGU Fellow, and a member of the National Academy of Sciences.

MPE Community Meeting - Informal Q&A and Conversations - September 12, 2024

We are pleased to announce the next Community Meeting for the SIAM activity group Mathematics of Planet Earth (MPE) this coming Thursday, September 12, at 10:00 a.m. EDT (22:00 CST-HK, 16.00 CEST, 14:00 UTC, 7:00 a.m. PDT). We will host our second informal discussion and Q&A sessions, where you chat with mid-career and senior researchers, educators, industry representatives, and SIAM professionals. The attendees can go to different breakout rooms for casual conversations with each other and an MPE officer, researcher, or professional.

Examples of discussions and Q&A topics include but are not limited to:

Career and job search tips (laboratory, university, industry, administration, government, etc.) Education and research advice (teaching, research topics, presentations, etc.) Specific MPE research areas Specific applied mathematics, computational science, or data science disciplines Work-family balance, hobbies, fun, continent-specific or country-specific Q&As Tips on funding, research proposals, program managers, and fund-raising Suggestions on paper writing, publications, journals, editorial jobs, etc. Codes, data, knowledge-sharing, social media Tips on service and leadership experiences SIAM organization, SIAM roles, how to get involved Suggestions for future SIAM MPE activities etc.
