Tellus A: Dynamic Meteorology and Oceanography is an open access journal focusing on all aspects of atmospheric dynamics and numerical weather prediction related to Earth science processes. Tellus A, along with its sister journal Tellus B: Chemical and Physical Meteorology, are international, peer-reviewed journals of the International Meteorological Institute in Stockholm, an independent non-for-profit body integrated into the Department of Meteorology at the Faculty of Sciences of Stockholm University, Sweden. The two journals serve an international community of researchers, policy makers, managers, media and the general public. Together they promote the exchange of knowledge about meteorology from across a range of scientific sub-disciplines. Topics covered in Tellus A include: dynamic meteorology; physical oceanography; data assimilation techniques; numerical weather prediction; climate dynamics and climate modelling and observation. Types of paper accepted include original research papers, review articles, brief research notes, Letters to the Editor, and special issues and conference proceeding. All articles are made freely and permanently available online through gold open access publication.
