CEDAR email: Advertizement of AGU Session 3632: Polar gravity wave dynamics and effects

[Mike Taylor]

Dear Colleagues,

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.

*Session ID # 3632* (SPA-Aeronomy)

*Session Title:* Polar Gravity Wave Dynamics and Effects

*Session Description:*

Gravity waves have long been known as a key driver of the general 
circulation and temperature structure of the middle and upper atmosphere 
through their ability to transport significant energy and momentum 
upwards from multiple tropospheric sources.Recent understanding of their 
effects on the middle atmosphere and coupled thermosphere/ionosphere has 
been significantly improved by theoretical, observational, and modeling 
studies.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.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 sources, propagation, instabilities, and 
effects on local, regional, and global scales.

*Conveners:* Mike Taylor, Utah State University, UT, USA; *Dave Fritts*, 
GATS, CO, USA; *Takuji Nakamura*, NIPR, Tokyo, Japan; *Irfan Azeem*, 
ASTRA, CO, USA.
