<p class="MsoNormal">Dear Colleagues, </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We invite you to participate in the gravity wave session at
the CEDAR workshop. This session will take place from 13:30-15:30 on Monday,
June 20 and from 16:00-18:00 on Thursday, June 23. If you would like to
present, please contact the conveners with your presentation title. </p>

<p class="MsoNormal"><span style="font-size:10pt;font-family:Cambria">Gravity Waves (GWs) play key roles in the
circulation, structure, and variability of the mesosphere and lower
thermosphere (MLT). The important roles of waves are mentioned in the “CEDAR:
The New Dimensions” strategic vision, which states that “the circulation and
variability of the upper atmosphere are dramatically impacted by waves that
carry energy and momentum upward from hurricanes, thermal tides, and surface
features.” Despite the known aspects of GW influences in the MLT, there remain
many questions regarding GW propagation environments, interactions with other
GWs, instabilities associated with dissipation and breaking, and the effects of
smaller-scale GWs (horizontal scales <100 km) that are believed to be very
important, but which have been challenging to quantify in many data sets. Also
needed is a more complete understanding of the coupling by GWs from lower
altitudes into the MLT and the ionosphere as noted in New Dimensions document
that “waves in particular are fundamental in boundary exchange processes as
they can transport fluxes of energy, momentum and composition across great
distances.” The proposed session aims to address questions related to GW
propagation and influences throughout the mesosphere, thermosphere, and
ionosphere.</span><span style="font-size:10pt;font-family:Cambria"></span></p>
