Rotational and divergent kinetic energy in the mesoscale model ALADIN
Kinetic energy spectra from the mesoscale numerical weather prediction (NWP) Charging model ALADIN with horizontal resolution 4.4 km are split into divergent and rotational components which are then compared at horizontal scales below 300 km and various vertical levels.It is shown that about 50% of kinetic energy in the free troposphere in ALADIN i
