Technical Note: Description and assessment of a nudged version of the new dynamics Unified Model

P. J. Telford, P. Braesicke, O. Morgenstern, and J. A. Pyle

Abstract. We present a "nudged" version of the Met Office general circulation model, the Unified Model. We constrain this global climate model using ERA-40 re-analysis data with the aim of reproducing the observed "weather" over a year from September 1999. Quantitative assessments are made of its performance, focusing on dynamical aspects of nudging and demonstrating that the "weather" is well simulated.
