SUMMARY:Stratified turbulence: a possible interpretation of some geophysic
 al turbulence measurements - Riley\, JJ (Washington)

DESCRIPTION:Stratified turbulence is a flow dominated by stable density st
 ratification\, and characterized by low internal Froude numbers and high R
 eynolds numbers\; in the present study it is also assumed that the Rossby 
 number is large. Flows in such parameter regimes occur often in the oceans
  and in the atmosphere. Results of direct numerical simulations of stratif
 ied turbulence\, some scaling arguments\, and implications regarding labor
 atory experiments will be presented. The results suggest that stratified t
 urbulence is a possible interpretation of some oceanic and atmospheric mea
 surements.
