This volume contains twenty papers on stably stratified flows, waves, and turbulence. A wide variety of techniques are described, ranging from numerical simulation, through laboratory studies, to field observations of the atmosphere. Some papers address fundamental aspects of turbulence in stably stratified flows such as turbulence collapse and local scaling. Six of the papers report investigations motivated by Antarctic field studies, reflecting the importance of that region for research on the stably stratified atmosphere. Eight papers deal with aspects of mixing in stably stratified flows, of which four are directly concerned with industrial applications. Observations of atmospheric internal gravity waves are discussed in two papers while a further two report studies of rotating, stratified flows with application to large-scale atmospheric and oceanic dynamics. In addition to applied mathematicians, this volume will interest researchers in meteorology, oceanography, and engineering.
