AMS provides access to the latest science as well as a community to help you advance.
Have an idea for a session topic at the 101st AMS Annual Meeting? Proposals are now due 8 April!
The AMS is a global community committed to advancing weather, water, and climate science and service.
We advance understanding through high-impact, peer-reviewed scientific publications—including the Bulletin of the American Meteorological Society (BAMS).
We bring together atmospheric scientists, professionals, students, authors, educators, researchers, and weather enthusiasts from around the world to share and collaborate.
We offer certification programs, online learning, and other professional development opportunities so that our members can learn, grow, and succeed.
We help educators and policy-makers bring the very latest weather, water, and climate science to bear on our nation’s future… and the world’s.
AMS provides access to the latest science as well as a community to help you advance.
Join a vibrant community of almost 12,000 professionals, students, and enthusiasts who share knowledge, improve technology, and disseminate science to ensure that our planet can thrive.
