GABLS4 Results from NCEP Single Column Model

GEWEX Atmospheric Boundary Layer Study (GABLS) 4 focuses on studying the interaction between the boundary layer and the surface in strong stability and during the diurnal transition focussing on the decrease of the turbulence. The DomeC on the Antarctic plateau is selected and the real case of 11-12 December 2009 is examined for a case study in GABLS4. In this presentation, the National Centers for Environmental Prediction (NCEP) global single column model (SCM) coupled with Noah land surface model (LSM) was performed with the GABLS4 approach. The NCEP SCM has 64 vertical levels, and the physical package includes non-local mixing scheme with stratocumulus-top-driven turbulence mixing. The Noah LSM includes one-layer snow scheme. Following the GABLS4 project outlines, a series of stages were carried out. The performance of boundary layer, surface fluxes and surface fields is investigated. Results from these experiments will be presented.
