WRF mesoscale model
Turbulence associated with mountain waves over Northern Scandinavia – a case study using the ESRAD VHF radar and the WRF mesoscale model
... The possibility that air masses flowing across the moun- tains might encounter regions of convective instability, is very important for the possibility of rapid vertical mixing. Figure 15 shows the occurrence rate of low ...
