Data set - Idealized ridge simulations with ICAR and WRF
收藏资源简介：
The simulations uploaded here constitute an idealized ridge experiment with a non-dimensional mountain height of 0.5. The ridge is specified by a witch of Agnesi function and the sounding characterized by a saturated, horizontally and vertically homogeneous atmosphere with constant and stable stratification. The witch of agnesi at the domain center ridge is 1 km high and has a half width at half maximum of 20 km. The vertical profile of the potential temperature was characterized with a surface temperature of T<sub>0</sub>=270 K and a constant Brunt-Väisälä frequency of N=0.01 s<sup>-1</sup>, corresponding to a mean increase of potential temperatur of 3.2 K/km or an average environmental lapse rate of -8.3 K/km. The horizontal wind components were chosen as U=20 m/s and V=0 m/s, and surface pressure as p<sub>0</sub>=1013 hPa. Saturated conditions with RH=100% were prescribed independently of height.<br> <br> For the configuration described above the vertical wavelength of the generated mountain-waves is 12.6 km and the non-dimensional mountain height, given by is 0.5. The critical value of the non-dimensional mountain height for the onset of wave breaking is 0.85, therefore wave breaking is not expected for the scenario defined above. However, the ocurence of non-linearities is. This way the results also serve as an indicator of how well the ICAR solution approximates scenarios in which non-linearities occur, a situation ICAR is very likely to encounter in real-world applications.
