Objective of the workshop

Workshop focus: Measurements and modeling of gravity wave dynamics and coupling in the Antarctic and Arctic regions.

New observational and modeling studies of atmospheric gravity waves have significantly improved our understanding of their important role for transporting energy and momentum within the middle atmosphere and the coupled thermosphere/ionosphere system. However, gravity wave fluxes and dynamical contributions at polar latitudes are not well understood, primarily due to a paucity of measurements. ANGWIN (Antarctic Gravity Wave Instrument Network) is a scientific program initiated in 2011 that utilizes a network of instrumentation operated at several international research stations around Antarctica with the primary research goal of quantifying and understanding the dominant sources, propagation and impact of such dynamical processes on a continental-wide scale. The goal of this workshop is to combine together new Antarctic and Arctic observations using optical and radio-wave techniques, and results with modeling studies to gain fresh knowledge and insight of their large-scale effects on the general circulation of the polar-regions lower, middle and upper atmosphere and ionosphere. Dynamical coupling processes associated with the gravity wave “hot spot” over the area between the Antarctic Peninsula and South American continent would also be discussed be focus during the workshop.

We solicit participation of potential scientists in this workshop which will include new ground-based and satellite observations, numerical modeling and theoretical studies of polar gravity wave sources, propagation, instabilities, and their effects on local, regional, and global scales.

The workshop is open to all interested researchers and will provide an excellent forum for post-graduate students.
