COFFIES Community Workshop - Tachocline
COFFIES Theme Workshop on the Tachocline
The COFFIES DRIVE Science Center is pleased to announce our first science-theme oriented virtual workshops on the first three Fridays of October. We aim to understand the solar cycle as the Consequence of Fields and Flows in the Interior and Exterior of the Sun (COFFIES). We welcome community participation in the discussions of science related to the Near-Surface Shear Layer (NSSL), the Tachocline, and Flux Transport & Emergence (FT&E). Zoom meetings will begin at 9 am PT on October 7, 14, and 21. Each session will review current understanding and provide time for brief contributed presentations.
The Tachocline is the thin layer of rotational shear at the bottom of the convection zone that potentially holds the key to understanding the solar dynamo process. Yet, the dynamical origin of the tachocline as well as its role in the generation, storage and transport of magnetic fields are still under debate. We plan to review state of the art observations, theoretical, and numerical models describing and explaining the properties of the tachocline.
We encourage participation with short contributions discussing new results and ideas, for observations and models, that may lead to a comprehensive view of the tachocline and its relevance for the solar dynamo.
Please send contributions to the Tachocline Theme Baristas: Nic Brummell and Gustavo Guerrero.
