Stratified turbulence: a possible interpretation of some geophysical turbulence measurements
Seminar Room 1, Newton Institute
Stratified turbulence is a flow dominated by stable density stratification, and characterized by low internal Froude numbers and high Reynolds 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 stratified turbulence, some scaling arguments, and implications regarding laboratory experiments will be presented. The results suggest that stratified turbulence is a possible interpretation of some oceanic and atmospheric measurements.
