Climate Variability in the Atlantic Ocean: Observations, Modeling, and Theories
Session ID#: 80077
Session Description:
Actively taking up and redistributing heat and carbon, the Atlantic Ocean significantly impacts regional and global climate via a series of modes of variability like the North Atlantic Oscillation (NAO), the East Atlantic Pattern (EAP), and the Atlantic Multidecadal Variability (AMV). These climate modes arise from a broad range of atmospheric and oceanic processes that are tightly coupled and span a wide temporal spectrum band. In recent years, significant progress has been made in advancing our knowledge and understanding of Atlantic climate variability and in predicting future climate change in this region. Therefore, there has been a pressing need to synthesize recent observational, modeling, and theoretical efforts.
This session invites abstract submission that address the mechanisms, impacts and predictability of climate variability in the Atlantic Ocean. Studies that involve atmospheric and oceanic observations, numerical/statistical modeling, and climate theories are welcomed.
