Malcolm leads a team working on developing and analysing higher resolution versions of Met Office global coupled climate models across space and time scales.

Areas of expertise
Developing higher resolution climate models.
Assessing impact of horizontal resolution on model characteristics.

Publications by M Roberts

Current activities
Malcolm's work aims to develop a hierarchy of resolutions of the current global coupled climate model, in collaboration with the NERC academic community as part of the Joint Weather and Climate Research Programme (Met Office) (NERC JWCRP). This enables the study of the impact of improving the representation of processes at higher resolution on the model's mean state, variability and extremes.This has evolved into an international effort to study the impact of model resolution in a multi-model context as part of the WRCP CMIP6 HighResMIP protocol, with the main European contribution as part of Horizon 2020 PRIMAVERA project.
