Alternative Formulations for Incorporating Lateral Boundary Data into Limited-Area Models

  title={Alternative Formulations for Incorporating Lateral Boundary Data into Limited-Area Models},
  author={Martina Tudor and Piet Termonia},
Limited-area models (LAMs) use higher resolutions and more advanced parameterizations of physical processes than global numerical weather prediction models, but suffer from one additional source of error—the lateral boundary condition (LBC). The large-scale model passes the information on its fields to the LAM only over the narrow coupling zone at discrete times separated by a coupling interval of several hours. The LBC temporal resolution can be lower than the time necessary for a particular… CONTINUE READING
