CEDAR email: CEDAR workshop: gravity waves session

[katrina bossert]

Dear Colleagues,



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.



Description:



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.
