dynamics offluids and turbulence...the picture I sent to you was an experiment on trapping of material inside (quite large, ~1m diameter) vortices in a huge rotating tank (14m diameter). I then moved to apply ideas of fluid dynamics to atmospheres, Mars' atmophere in particular. At the moment, I study Martian dust storms and other planetary atmosphere phenomena, such as polar vortices. I always try to come back to the lab when I can, I've just finished a lab campaign a few weeks ago on producing "polar vortices" in the same 14-m rotating tank I told you above, and studying instabilities and coherent vortices which form under particular conditions.
