Dr Bruce Macpherson
Bruce leads the development of operational convective-scale data assimilation systems in Numerical Weather Prediction models in the Met Office.
Bruce manages the convective-scale data assimilation team which is part of Data Assimilation and Ensembles. The team focuses on improving the assimilation of observations into the operational UK model and other limited-area models covering different regions of the globe. The aim is to improve analyses and forecasts of key weather elements such as rain, cloud, visibility, screen temperature and 10-metre wind. An increasing focus is the area of 'NWP-nowcasting', which is concerned with timely issue of frequently updated forecasts for the 0-12 hour time period.
Bruce has worked on data assimilation since starting at the Met Office in 1985. He began work on initialisation of global models and helped develop the Analysis Correction assimilation scheme used operationally from 1988-1999. Later he worked on assimilation of radar rainfall rates by Latent Heat Nudging and cloud data by moisture nudging, techniques which became operational in the mid-1990s. He moved on to help introduce the first operational scheme for variational assimilation of visibility observations. He was also involved in the introduction of a 4D-Var scheme into the North Atlantic and European Model.
Prior to joining the Met Office, Bruce graduated in Applied Maths and Theoretical Physics from the University of St Andrews. He then completed a PhD on flow and sediment transport over steep sand ripples at the Department of Applied Mathematics and Theoretical Physics in the University of Cambridge.
- Bruce is the current chair of the Expert Team on Data Assimilation and Use of Observations of the Short-Range Numerical Weather Prediction Programme of EUMETNET.
- From 1999-2004, Bruce was chair of Working Group 3 of European Action COST-717: 'Use of Radar Observations in Hydrological and NWP models'.
