[A-AS06] Stratosphere-troposphere Processes And their Role in Climate

Thu. Jun 3, 2021 1:45 PM - 3:15 PM Ch.06 (Zoom Room 06)

convener:Takenari Kinoshita(Japan Agency for Marine-Earth Science and Technology), Takatoshi Sakazaki(Graduate School of Science, Kyoto University), Masashi Kohma(Department of Earth and Planet Science, Graduate School of Science, The University of Tokyo), Nawo Eguchi(Kyushu University), Chairperson: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 the present and future climate. Both observed data and high-resolution models have now clearly demonstrated that stratospheric processes can affect various tropospheric phenomena. On the other hand, it has been confirmed that the stratospheric processes are changing significantly with climate change. For example, the polar vortex was exceptionally strong, cold, and persistent in the Northern Hemisphere winter stratosphere in 2019-2020, resulting in record ozone depletion and contributing to unusually warm temperatures in mid-latitudes.
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.
