Citation | Professor Michael Proctor is internationally recognised for his fundamental contributions to nonlinear convection theory and to the understanding of fluid dynamos. With WVR Malkus, he was the first to appreciate the role of the backreaction of magnetic field distortion on the mean dynamo flow - the so-called Malkus-Proctor-effect - and showed that the appropriate scaling for geomagnetic equilibration is independent of viscosity. Michael's guiding principle is to synthesize predominating dynamical factors into a simple model equation which can then be studied under a wide variety of conditions to obtain a global view of the generic behaviour of the system under investigation. |
