| 1026 | then |
|---|
| 1027 | the plot only consists of one panel, since no profiles of the potential |

|---|
| 1029 | to <b>data_output_pr </b>whose names do not appear in <b>cross_profiles</b>, |
|---|
| 1030 | then the respective profile data are output (<a href="chapter_3.4.html#PLOT1D_DATA">PLOT1D_DATA</a>) |

| 6332 | its accuracy is several orders of magnitude worse, but this does not |

| 6333 | affect the accuracy of the simulation). Nevertheless, the user should |

| 6452 | <p>A |
|---|
| 6453 | so-called Rayleigh damping is applied to all prognostic |
|---|
| 6454 | variables if a non-zero value is assigned to <b>rayleigh_damping_factor</b>. |
|---|
| 6455 | If switched on, variables are forced towards the value of their |
|---|
| 6456 | respective basic states (e.g. the geostrophic wind). The intensity of |
|---|
| 6457 | damping is controlled by the value the <b>rayleigh_damping_factor</b> |
|---|
| 6458 | is assigned to. |
|---|
| 6459 | The damping starts weakly at a height defined by <a href="#rayleigh_damping_height">rayleigh_damping_height</a> |
|---|
| 6460 | and rises according to a sin<sup>2</sup>-function to its |
|---|
| 6461 | maximum value |

| 6463 | the top (ocean: bottom) boundary. </p> |

|---|
| 6466 | |
|---|
| 6467 | |
|---|
| 6468 | |
|---|
| 6469 | <p>This method |
|---|
| 6470 | effectively damps gravity waves, caused by boundary layer convection, |
|---|
| 6471 | which may spread out vertically in the inversion layer and which are |
|---|
| 6472 | reflected at the top (ocean: bottom) |
|---|
| 6473 | boundary. This particularly happens with the upstream-spline scheme |
|---|
| 6474 | switched on (see <a href="chapter_4.1.html#momentum_advec">momentum_advec</a> |
|---|
| 6475 | or <a href="chapter_4.1.html#scalar_advec">scalar_advec</a>). |
|---|
| 6476 | Therefore, with this scheme the Rayleigh damping is switched on (<b>rayleigh_damping_factor</b> |
|---|
| 6477 | = <i>0.01</i>) by default. Otherwise it remains switched |
|---|
| 6478 | off. </p> |

|---|
| 6481 | |
|---|
| 6482 | |

|---|
| 6484 | <p>The Rayleigh damping factor must |
|---|
| 6485 | hold the condition <i>0.0</i> |
|---|
| 6486 | <= <b>rayleigh_damping_factor</b> |
|---|
| 6487 | <= <i>1.0</i>. Large values (close to <span style="font-style: italic;">1.0</span>) can cause |
|---|
| 6488 | numerical instabilities.</p> |
