Summary of scientific research
Main contributions in geophysics (geomagnetism, meteorology, geodesy, oceanography, etc.), planetary physics, fluid mechanics and nonlinear dynamics. His work on the hydrodynamics and magnetohydrodynamics (MHD) of spinning fluids has elucidated flow phenomena in planetary atmospheres, oceans and interiors. In laboratory studies of 'sloping thermal convection' he discovered various régimes of 'vacillation' and other multiply-periodic flows and aperiodic flows ('geostrophic turbulence'), which findings (a) influenced seminal mathematical studies of deterministic chaos and (b) provided a paradigm for interpreting large-scale flows in planetary atmospheres. Other contributions include the concept of 'dynamic superhelicity' as well as general theoretical results tested by crucial laboratory experiments on boundary layers and detached shear layers. His research on fluctuations in the Earth's rotation led to new developments in meteorology, oceanography and studies of the Earth's deep interior. He introduced new types of self-exciting dynamo which show promise as low-dimensional theoretical models for investigating temporal fluctuations of stellar and planetary magnetic fields, including the irregular timeseries of geomagnetic polarity reversals. His discovery of 'nonlinear quenching' made during the course of this work has wide implications in the study of nonlinear systems. His contributions to electrodynamics and MHD include the concepts of 'potential magnetic field' and 'electrodynamic superhelicity' and discoveries of (a) basic theorems and other general results, (b) new types of MHD wave motion expected to occur in spinning planets and stars, (c) methods for locating interfaces and investigating their properties. He initiated research on the electromagnetic effects of hypervelocity impacts in connection with the magnetism of small bodies (Moon, meteorites, asteroids) in the Solar System.
