This session is scheduled for Tuesday, June 21, 2022, from 10:00 AM - 12:00 PM CST.</font></p>

<p style="margin:0px;text-align:justify;font-stretch:normal;line-height:normal;color:rgb(0,0,0)"><font face="arial, sans-serif">Workshop Description:</font></p>
<p style="margin:0px;text-align:justify;font-stretch:normal;line-height:normal;color:rgb(0,0,0)"><font face="arial, sans-serif">Synoptic atmospheric hazards, such as hurricanes and strong frontal activity, and defined geological hazards, such as seismic and volcanic activities, can trigger acoustic and gravity waves that propagate upwards and are able to be detected in the upper atmosphere. Observation and modelling of these events can give new insights into our understanding of the dynamics, chemistry, and fundamental coupling processes between the troposphere and the middle and upper atmosphere. In system theory, such lower atmospheric events can be thought of as a defined input, x(t), into a complex system, h(t), where the CEDAR community can observe y(t) and gain insight on the fundamental transfer function(s) representing the underlying physical processes controlling the upper atmospheric response. This workshop welcomes short interactive presentations on the upper atmospheric response to various natural phenomena occurring in the oceans, on land, and in the lower atmosphere. Such phenomena include, but are not limited to, earthquakes, surface and submarine volcanic eruptions, tsunamis, typhoons, cyclones, hurricanes, tornados, thunderstorms, etc., which are studied from different observational and modeling approaches. The workshop seeks to bring together research communities from different disciplines and backgrounds so as to fundamentally develop a deeper understanding of the geophysical processes involved. It is anticipated that the impact of this activity can lead to new projects related to natural hazard-induced upper atmospheric dynamics, including research-based tools that may lead to early warning systems against such natural disasters.</font></p>
