Dr Helen Webster

Helen works on the development, validation and use of the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME).

Areas of expertise

Helen's areas of expertise include:

My Publications - Webster, H

Current activities

Helen's main focus is on the scientific development of Met Office Dispersion Model. Recently, she has been improving the representation of wet and dry deposition processes and gravitational settling of heavy particles. As part of this research project, she has implemented a land use dependent dry deposition scheme.

Career background

Helen has worked in atmospheric dispersion since joining the Met Office in 1999. Her model development work has included the areas of plume rise modelling, turbulence and meander parametrisations, and deposition schemes. Helen has also used Met Office Dispersion Model to support measurement campaigns and to model air pollution events such as the Buncefield oil depot incident in December 2005. She is occasionally involved in training in atmospheric dispersion and NAME, and emergency response role work during incidents such as the eruption of Eyjafjallajokull in April / May 2010.

Prior to joining the Met Office, Helen studied for a mathematics degree and a PGCE in secondary mathematics at Oxford University. She then completed an applied mathematics PhD on integrable nonlinear differential equations at the University of Kent at Canterbury.
