2020 Workshop: Whole atmosphere coupling
Yosuke Yamazaki
Jorge Chau
Coupling of atmospheric layers is one of the central topics of CEDAR workshop. Sudden stratospheric warming (SSW), a large-scale meteorological disturbance, has been associated with profound anomalies in the Earth atmosphere, and connects atmospheric regions from the troposphere all the way to the upper thermosphere and ionosphere. During the last decade, numerous studies showed that Arctic sudden stratospheric warmings cause large global disturbances in the ionosphere, thermosphere, and mesosphere. Sudden stratospheric warming of September 2019 enabled new studies aiming to examine whether Antarctic SSW have similar global impact on the upper atmosphere. This workshop aims to promote discussions and collaborations between scientists working on different aspects of whole atmosphere coupling. We welcome both contributions focused on SSW events of the solar cycle 24 and contributions that examine atmospheric coupling in more general terms, including studies of connections through gravity waves, tides, and planetary waves.
