Evolution of Urban Surface Exchange in the UK Met Office’s Unified Model

The UK Met Office model the Unifed Model (UM) has undergone a series of refinement to introduce urban characteristics in the surface scheme over the last decade. As these have been used operationally the philosophy is to retain simplicity and computational cheapness while capturing as much as possible the behaviour of urban areas in modifying surface fluxes. The different steps that have been taken and their performance are outlined.
