Description

The focus here is on a case of quasi-stationary convection over the southwest peninsula of the UK, which was forced by a narrow convergence line. A sensitivity test is required to investigate to what extent the convergence is due to the roughness gradient along the coastline. To do this the UM code will be editted to set the roughness length for momentum over land equal to that over sea (possibly over a subset of the full domain). This change will likely be carried out in the control routine ATM_STEP.F90.
