<div>Dear Colleagues,<br>
<br>
Final Reminder: We invite you to participate in our new session at the Fall AGU on "Polar Gravity Wave Dynamics and Effects". Please submit your abstract by the deadline of August 6, 2014.

and temperature structure of the middle and upper atmosphere through their ability to transport significant energy and momentum upwards from multiple tropospheric sources.<span style="">
</span>Recent understanding of their effects on the middle atmosphere and coupled thermosphere/ionosphere has been significantly improved by theoretical, observational, and modeling studies.<span style="">
</span>However, the contributions of gravity waves at polar latitudes, including their interactions with the thermosphere and space weather environment, are not well understood, primarily due to a paucity of measurements.<span style="">
</span>Recent satellite missions and ground-based instrument networks are contributing new data for studying polar gravity wave dynamics and their effects in both the Arctic and Antarctic regions. We solicit papers focusing on new observational, theoretical,
and modeling studies of polar gravity wave <span style=""> </span>sources, propagation, instabilities, and effects on local, regional, and global scales.
