Abstract: | We expect from turbulence fragmentation, mixing and loss of coherence.An inverse cascade, however, proceeds from small to large scales and brings some self-organization and eventually appearance of a coherent system-size condensate. I shall briefly review what we know (little from theory and a lot from experiments) about turbulence-condensate interaction. The main focus will be on 2d fluid turbulence where the condensate is a vortex, but brief comparison with a Bose-Einstein condensate will be given. Applications to atmospheric phenomena will be briefly discussed. |
