2903 | This applies to both 3d volume and cross section data. The length of |

2945 | <= ny+1 are output so that in case of cyclic boundary conditions |

2946 | the |

3013 | constructed by appending the four digit processor ID, e.g. |

3014 | <filename>_0000, <filename>_0001, etc.). |
---|
3015 | After PALM has |

3017 | files are sampled into one final file<span style="font-weight: bold;"></span> |

3033 | one |

---|
8665 | By default, depending on the type of the parallel computer, PALM |
---|
8666 | generates a 1d processor |
---|
8667 | net (domain decomposition along x, <span style="font-weight: bold;">npey</span> |
---|
8668 | = <span style="font-style: italic;">1</span>) or a |
---|
8669 | 2d-net (this is |
---|
8670 | favored on machines with fast communication network and/or large number of processors (>256)). In case of a |
---|
8671 | 2d-net, it is tried to make it more or less square-shaped. If, for |
---|
8672 | example, 16 processors are assigned (-X 16), a 4 * 4 processor net is |
---|
8673 | generated (<span style="font-weight: bold;">npex</span> |
---|
8674 | = <span style="font-style: italic;">4</span>, <span style="font-weight: bold;">npey</span> |
---|
8675 | = <span style="font-style: italic;">4</span>). |
---|
8676 | This choice is optimal for square total domains (<a href="chapter_4.1.html#nx">nx</a> |
---|
8677 | = <a href="chapter_4.1.html#ny">ny</a>), |
---|
8678 | since then the number of ghost points at the lateral boundarys of |
---|
8679 | the subdomains reaches a minimum. If <span style="font-weight: bold;">nx</span> |
---|
8680 | and <span style="font-weight: bold;">ny</span> |
---|
8681 | differ extremely, the |
---|

9666 | <p>A |
---|
9667 | so-called Rayleigh damping is applied to all prognostic |
---|
9668 | variables if a non-zero value is assigned to <b>rayleigh_damping_factor</b>. |
---|
9669 | If switched on, variables are forced towards the value of their |
---|
9670 | respective basic states (e.g. the geostrophic wind). The intensity of |
---|
9671 | damping is controlled by the value the <b>rayleigh_damping_factor</b> |
---|
9672 | is assigned to. |
---|
9673 | The damping starts weakly at a height defined by <a href="#rayleigh_damping_height">rayleigh_damping_height</a> |
---|
9674 | and rises according to a sin<sup>2</sup>-function to its |
---|
9675 | maximum value |
---|
9676 | at |
---|
9677 | the top (ocean: bottom) boundary. </p> |

9685 | |

9686 | |
---|
9687 | <p>This method |
---|
9688 | effectively damps gravity waves, caused by boundary layer convection, |
---|
9689 | which may spread out vertically in the inversion layer and which are |
---|
9690 | reflected at the top (ocean: bottom) |
---|
9691 | boundary. This particularly happens with the upstream-spline scheme |
---|
9692 | switched on (see <a href="chapter_4.1.html#momentum_advec">momentum_advec</a> |
---|
9693 | or <a href="chapter_4.1.html#scalar_advec">scalar_advec</a>). |
---|
9694 | Therefore, with this scheme the Rayleigh damping is switched on (<b>rayleigh_damping_factor</b> |
---|
9695 | = <i>0.01</i>) by default. Otherwise it remains switched |
---|
9696 | off. </p> |

9706 | <p>The Rayleigh damping factor must |

9708 | <= <b>rayleigh_damping_factor</b> |

9709 | <= <i>1.0</i>. Large values (close to <span style="font-style: italic;">1.0</span>) can cause |
