| Scope | 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. | |
