The Atmospheric Sciences parallel session will address the most pressing challenges and exciting frontiers in our understanding of the Earth’s gaseous envelope. The initial focus is on phenomena with direct and significant societal impact, covering advances in the study of extreme weather events and the continuous improvement of weather forecasting. This segment invites contributions on the dynamics, predictability, and attribution of high-impact events such as tropical cyclones, floods, and heatwaves. We encourage presentations on cutting-edge numerical weather prediction (NWP) techniques, ensemble forecasting, data assimilation methods, and the development of robust early warning systems designed to enhance community resilience and inform effective disaster mitigation strategies.

Delving into the core principles that govern atmospheric behavior, the session will feature in-depth discussions on atmospheric physics and dynamics. This cornerstone of our field explores the fundamental thermodynamic processes, fluid motions, and radiative transfer that drive weather and climate systems across all scales. Expanding our view vertically, we will also explore the critical domains of the middle and upper atmosphere. We welcome research on topics such as stratospheric-tropospheric coupling, atmospheric waves, ozone chemistry, and the influence of solar and geomagnetic activity on atmospheric composition and circulation, highlighting the interconnectedness of our entire atmospheric column.

Finally, the session broadens its temporal and disciplinary scope to examine long-term patterns and ecosystem interactions. Presentations on climate variability will investigate the natural modes of the climate system, such as the El Niño-Southern Oscillation (ENSO) and the Madden-Julian Oscillation (MJO), and their profound influence on regional weather patterns and seasonal outlooks. In parallel, the session will explore biometeorology, a critical interdisciplinary frontier examining the complex interactions between atmospheric processes and living organisms. This includes studies on the effects of weather and climate on agriculture, forestry, human health, and the spread of vector-borne diseases, underscoring the vital role of atmospheric science in navigating our changing world.
