SUMMARY:Formation of large-scale vortices in rotating convection - Dr. Cel
 ine Guervilly (University of Leeds)
DTSTART:20140609T150000Z

UID:TALK50742@talks.cam.ac.uk
CONTACT:Adrian Barker
DESCRIPTION:Using numerical simulations of rotating Boussinesq convection 
 in a Cartesian box\, we study the formation of long-lived\, large-scale\, 
 depth-invariant vortices. These vortices\, which are always cyclonic in th
 e explored parameter range\, grow to the largest horizontal size permitted
  in the computational domain. We will first discuss the domain of existenc
 e of these vortices\, the possible mechanisms by which they form\, and how
  they affect the flow of heat through the system. In the second part of th
 is talk\, we will describe how they interact with self-sustained magnetic 
 field.
