European High-Performance Infrastructures
in Turbulence

The purpose of the present project is to investigate the generation and the propagation of internal gravity waves excited by convection at the stratified/convective zones interface by the baroclinic instability of an initially stratified layer with salt. Encouraged by our first observations (Project EuHIT Barostrat), we would like now to investigate more deeply the possible generation and propagation of IGWs for this new, salt-stratified version of the baroclinic instability. The objective will be first to explore the parameter space where IGWs can be observed. That is to describe their physical properties like amplitude, frequency, wavelength as a function of the input parameters. Moreover, we will investigate these properties also for the IGWs that are emitted into the passive layer mimicking the stratosphere. This includes to search for those parameters that will give the strongest radiation of waves into the passive layer. The confirmation of the generation of Internal Gravity Waves in this set-up will be a remarkable discovery, useful in particular for atmospheric sciences.
