MScConservative numerical methods for climate models: Recently new numerical methods have been developed for climate models, which allow to reduce the horizontal numerical diffusion significantly. The question arises which grid resolution is needed to simulate certain meteorological phenomena using the conservative numerical methods. Hereto different idealized and real case simulations can be used.A high resolution reference simulation shall be conducted and a series of simulations for different resolutions and numerical schemes with the COSMO model for one of the test cases described further below. Hereby a reference test case configuration can be used. The resolutions which provide similar simulation quality shall be assessed for the numerical schemes investigated.
  • 2.1 Flow over the 3D mountain test case allows investigating the dependency of the solution independent on model parameterisations. The uniform stratified flow meets a hill having an idealized shape and its vertical and horizontal structure is modified. For mountains high enough the air passes the hill left and right. If the tream flow is fast enough the downstream velocity field is turbulent.
  • 2.2 The 2D cold bubble test case allows to investigate the development of turbulent motion in a fully compressible, non-isothermal model system. A cold bubble is initialized, falls down and rolls of mixed cold and surrounding warm air propagate along the surface.
