Professor of Atmospheric Physics and Head of Department of Physics, Imperial College London

Distinguished for her scientific leadership in the area of solar influences on the middle atmosphere and for her modelling of how these effects can modulate tropospheric circulations and so propagate to Earth's surface. Her expertise in modelling atmospheric radiative transfer allowed the development of computationally fast but accurate radiative transfer schemes some of which are now in use by climate modelling groups across the world. By proposing and demonstrating an entirely novel mechanism for solar influence on climate she has allowed proper allowance to be made for the small and subtle, yet revealing effects.
