[A-AS10] Stratosphere-troposphere Processes And their Role in Climate

Thu. May 26, 2022 1:45 PM - 3:15 PM 106 (International Conference Hall, Makuhari Messe)

convener:Masashi Kohma(Department of Earth and Planet Science, Graduate School of Science, The University of Tokyo), convener:Masakazu Taguchi(Aichi University of Education), Takenari Kinoshita(Japan Agency for Marine-Earth Science and Technology), convener:Nawo Eguchi(Kyushu University), Chairperson:Nawo Eguchi(Kyushu University), Masashi Kohma(Department of Earth and Planet Science, Graduate School of Science, The University of Tokyo)

The dynamical, radiative, and chemical processes involved in the interactions between the stratosphere and troposphere are essential for understanding present and future climate. Both observed data and high-resolution models have now clearly demonstrated that stratospheric processes can affect various tropospheric phenomena. Recently, there have been many studies suggesting a strong link between stratospheric processes and the tropical troposphere. Examples include the impact of the equatorial stratospheric Quasi-Biennial Oscillation (QBO) on the Madden-Julian Oscillation (MJO) and the enhancement of tropical convective activity associated with the Sudden Stratospheric Warming (SSW). In addition, as in other atmospheric and earth science fields, there is a growing body of research based on the latest statistical and informatics methods, such as data assimilation, large-ensemble simulations, and machine learning.
In this session, we will focus on stratospheric phenomena and invite presentations on the latest findings (case studies, long-term variations, predictability, etc.). We welcome studies on the effects of these phenomena on the troposphere and mesosphere. Inheriting the significance of the Stratosphere-troposphere Processes And their Role in Climate (SPARC) sessions held at JpGU, this division aims to enhance the development of this field in close cooperation with the atmospheric chemistry sessions.
