Joint Session 4 Whole Atmosphere Coupling during Extreme Events. Part I

Wednesday, 9 January 2019: 1:30 PM-2:30 PM
North 227A-C (Phoenix Convention Center - West and North Buildings)
Hosts: (Joint between the 16th Conference on Space Weather; and the 20th Conference on Middle Atmosphere )
Larisa Goncharenko, Massachusetts Institute of Technology, Haystack Observatory, Westford, MA

Some types of extreme events are known to produce large and long-lasting anomalies not only locally, in the area of the immediate impact, but also in atmospheric regions thousands of kilometers away. The session invites studies that demonstrate both the downward and upward vertical coupling mechanisms, that is, connections from the upper atmosphere down to the troposphere, and from the troposphere and stratosphere up to the thermosphere and ionosphere. This session will explore two types of extreme events—sudden stratospheric warmings and energetic particle precipitation—and discuss dynamical, thermal, and chemical effects of such events. Contributions on other types of events are also welcome.
