• Description:
  "There are several techniques available which reduce space truncation error in grid point atmospheric models. Two of them have been used in the seven-layer primitive equation model (7L PE) at NMC. The first one uses a finer grid mesh to obtain more accurate resolution of meteorological waves- the smaller grid spacing also makes the finite differences closer approximations to the continuous equations. By changing grid distance from 1 bedient (381 km at 60°N) to ¹/₂ bedient, the operational hemispheric 7L PE model has successfully reduced the effects of spatial truncation error - translational speeds of meteorological waves have been improved and both locked-in error and cross contour flow problems have been reduced"--Introduction.
