Do the UKCP09 projections include the Urban Heat Island (UHI) effect?

The UKCP09 probabilistic projections do not include any recognition of urban land-use and there is no account of a potential exacerbation of Urban Heat Island effects under climate change.

In detail

The new generation HadRM3 model does include a representation of the Urban Heat Island by including in each grid square a score of urban-ness. However, this model was developed after the UKCP09 methodology was finalised so this was not used for the UKCP09 modelling.
