The Changing Width of the Tropical Belt Working Group was formed in 2016 to further the understanding of new insights that call into question the prevailing view about the nature and causes of changes in the width of the tropics. Read about the impacts and activities of the Working Group and the International Space Science Institute (ISSI) Tropical Width Diagnostics Intercomparison Project on this topic in the recently published BAMS paper, "Tropical Widening: From Global Variations to Regional Impacts."

The American Meteorological Society will be hosting its 101st Annual Meeting January 10-14 in New Orleans, Louisiana with considerations of added virtual options. The annual theme for the upcoming AMS Annual Meeting focuses on stengthening engagement with communities through our science and service. Included are a number of sessions relevant to the US CLIVAR community. Abstact submission for most conferences/symposia is August 24, 2020.

The latest news, meetings, jobs, and funding opportunities for the climate science community in our July Newsgram.

The 2020 AGU Fall Meeting will be held from December 7-11 virtually (mostly), in San Francisco (possibly), and in other regional hubs (if it is safe). In preparation for the meeting, we have compiled a list of sessions and town halls that are relevant to the community and organized by our Panels, Working Groups, and community members. The list of sessions is not intended to be exhaustive but to help digest the collection of the hundreds of sessions and events. Abstract submissions are due July 29, 2020.

The Workshop on Societally-Relevant Multi-Year Climate Predictions is now rescheduled for June 2-4, 2021. The plan is to hold this as an in-person meeting with opportunity for remote participation for those unable to travel. Registration and poster abstract submission will open again this fall for additional participants.

Mark your calendars with the new dates for the Workshop on Observing, Modeling, and Understanding the Circulation of the Arctic Ocean and Sub-Arctic Seas to be held July 12-15, 2021 in Seattle, Washington. The organizing committee will initiate an online topical community discussion this summer to share perspectives in advance of the workshop. Registration and abstract submission will open this winter.

Join us Wednesday June 17 at 2pm ET for the PPAI Panel Webinar Series. This webinar will be the first of two talks on the theme of S2S prediction/predictability. Michelle L'Heureux (NOAA CPC) will present her talk entitled "Overview of S2S Precipitation Products over the US and Sources of Skill for Wintertime California Precipitation"

The Data Science Webinar Series aims to accelerate the understanding, adoption, and further development of modern data science tools (artificial intelligence, machine learning, and statistics) for the analysis of large-to-massive climate data sets. Join us on June 22 for a talk by Pulong Ma (Duke University) on "Efficient Surrogate Modeling for Uncertainty Quantification in Assessment of Remote Sensing Retrievals and Storm Surges"

We are pleased to announce the US CLIVAR Data Science Working Group Webinar Series. Organized by the Data Science Working Group, the webinar series will feature in experts in Earth science, statistics, and computer science with the specific goal of fostering collaboration across these disciplinary boundaries. We are excited to have Bin Yu (University of California Berkeley) kick us off on June 8.
