The dynamical, radiative, and chemical processes involved in the stratosphere-troposphere (ST) interactions are essential for understanding the formation and change/variations of the climate. Both observational data and high-resolution models have now clearly demonstrated that stratospheric processes can affect various tropospheric phenomena.
Recent research directions include, but are not limited to, better understanding of ST interaction processes, verification and development of subseasonal-to-seasonal predictions of ST coupled variations, and development of statistics-/informatics-based studies. Studies are also notable that treat the stratosphere and mesosphere integrally as the "middle atmosphere" and that deal with the "whole atmosphere" extending from the surface (land and ocean) to the upper atmosphere (the thermosphere and ionosphere). Due to the above background, the SPARC name will be changed for APARC (Atmospheric Processes and their Role in Climate) from 1 January 2024.
In this session, we welcome studies focusing on various ST processes as well as those extending the target upward to the mesosphere and upper atmosphere and/or downward to the surface. Inheriting the significance of the Stratosphere-troposphere Processes And their Role in Climate (SPARC) sessions held at past JpGU meetings, this division aims to enhance the development of this field in close cooperation with the atmospheric chemistry session.
