4 | | Since revision -r3347 a mesoscale nesting is available, which allows to nest a PALM domain within a mesoscale model. Therefore, time-dependent values for the three velocity components, potential temperature as well as the mixing ratio for the lateral and top boundaries of the PALM model domain are stored in the [../iofiles/pids#dynamic_input dynamic] input file and are read and mapped onto the respective arrays during the simulation. This way, it is possible to account for evolving synoptic conditions during the simulation without adding further tendency terms or to nudge the LES solution. Please note, the mesoscale is designed as an inter-model one-way offline nesting where the mesoscale simulation runs in advance. The mesoscale offline nesting needs to be distinguished from PALM's [../nesting_parameters self-nesting], which is designed as an two-way (one-way possible) model-coupling between PALM simulations during the time-integration. |
