Dr John Edwards

John works on the atmospheric boundary layer.

John works on the relationship between the atmospheric boundary layer and the underlying surface.

Current activities

John is a research scientist working to improve the representation of surface processes in numerical forecasting models, with a particular interest in the surface layer. The surface layer is the lowest part of the atmospheric boundary layer and is strongly influenced by exchanges of heat, moisture and momentum with the underlying surface. John uses observational data and process models to form a detailed picture of processes in the surface layer and to identify areas for improvement in current forecasting models.

A major theme in John's current work is understanding the variation of temperature near the surface, particularly in light winds and conditions of strong surface cooling. This has led to a developing interest in the use of land surface temperatures retrieved from satellites to assess the performance of operational models.

The marine surface layer forms another focus of John's current interests, where the emphasis is on developing better representations of the mutual interactions between the atmosphere, the ocean and surface waves. John is also involved in the GEWEX Atmospheric Boundary Layer Study (GABLS), an international collaboration which seeks to improve the treatment of stable boundary layers in numerical forecasting models by comparing the results of a range of different models with field observations.

Career background

John has been a member of Atmospheric Processes and Parametrizations since 2003, during which time his main interests have been in the stable boundary layer; the use of field observations to assess the performance of forecasting models; and the parametrization of surface transfer at the oceanic surface. Previously, John worked on parametrization of atmospheric radiation in the Met Office Hadley Centre, developing the radiation code used in the Unified Model.

John holds a PhD in astrophysical fluid dynamics from the University of Cambridge, from which he also received his first degree in Mathematics.
