v37 v38 203 203 In order to prevent gravity waves from being reflected at the top boundary, a sponge layer (Rayleigh damping) can be applied to all prognostic variables in the upper part of the model domain ([#klemp1978 Klemp and Lilly, 1978]). Such a sponge layer should be applied only within the free atmosphere, where no turbulence is present. 204 204 205 The model is initialized by horizontally homogeneous vertical profiles of potential temperature, specific humidity(or a passive scalar), and205 The model is initialized by horizontally homogeneous vertical profiles of potential temperature, water vapor mixing ratio (or a passive scalar), and 206 206 the horizontal wind velocities. The latter can be also provided from a 1-D precursor run (see Sect.[wiki:doc/tec/1dmodel 1-D model for precursor runs]). Uniformly distributed random perturbations with a user-defined amplitude can be imposed to the fields of the horizontal velocities components to initiate turbulence. 207 207
