Short summary
This is the first time that a low-level jet observed above the East Antarctic Plateau is simulated by a regional climate model. This paper illustrates in a 3-D simulation the respective influences of the large-scale pressure gradient force and turbulence on the onset of the low-level jet. As atmospheric turbulence plays a key role in explaining the behaviour of chemical tracers during the OPALE campaign, this paper also increases our confidence in using the outputs of the model for this purpose.
