Supplement to: Interpretation for use of surface wind speed projections from the 11-member Met Office Regional Climate Model ensemble

This document provides supplementary material to the techincal note on "Interpretation for use of surface wind speed projections from the 11-member Met Office Regional Climate Model ensemble". As noted in the UK Climate Projections (UKCP09) Technical note on Wind (Brown et al., 2009), the RCM surface wind speeds show biases when compared to long-term climatological means derived from observations, or from atmospheric reanalysis datasets. Biases that vary with location and season that can be attributed to aspects of the parameterisation of unresolved orography and surface roughness. As such, Brown et al. recommend that when exploiting the RCM wind data, the consequences of these climatological biases should be carefully assessed in the context of the intended application.
