The Geophysical Turbulence Program

The scientific leaders of NCAR recognized early on that in order to understand the dynamics of the atmosphere and oceans, the sun and solar-terrestrial interactions, investigating relevant turbulent processes at a fundamental level would be essential.
Reactive flows, aerosols and turbulent mixing, cloud physics and convection, turbulent interfaces and anisotropies, quasi-geostrophic or stratified flows, the dynamics of passive vs. active scalars and that of magnetized plasmas are topics of current interest, together with code and model developments e.g., Large Eddy Simulations (LES) and its variants such as super-parametrization (with a newly-created NSF center at CSU).

In this context, GTP provides channels for interaction and information-sharing among NCAR and other scientists engaged in fundamental and applied geophysical turbulence research at NCAR and in the broader community, including (in today's
parlance) outreach activities.
GTP organizes yearly one or two workshops on varied themes, has a few long-term visitors (from one week to, rarely, one year) and holds monthly seminars. Visitors and workshops are chosen in an open yearly meeting.
One can consult the list of the 6 GTP Workshops, the 42 seminars and the 12 other Visitors with their affiliations for the last three years in the white paper.
