Sažetak
Analytical and numerical modeling of simple katabatic flows blowing over long cool slopes is assessed. Since it was verified that classical scaling via Monin-Obukhov length performs over such slopes rather poorly (a low-level jet usually determines the surface fluxes), our improved Prandtl model is used instead. We specifically address a single problem: the mixing length-scale within the SABL, i.e. in the "z-less" or local regime, as often parameterized in mesoscale models with a higher-order closure turbulence scheme, and a way to improve this length-scale by including shear effects explicitly. The numerical meteorological model deployed is MIUU model ; it is improved via its mixing length-scale (in its turbulence parameterization scheme) by its tune up toward the improved Prandtl solutions. In this way, lower and more faithful low-level jets and near-surface inversion may be modeled.

Napomena
Projekt NATO-DMI, BORA (119-1193086-1311) ; Autor je pozvan, kao međunarodni ekspert za stabilne atmosferske granične slojeve i posebice katabatičko strujanje, da održi predavanje i moderira predstojeći bilateralni znanstveni projekt između Nizozemske (IMAU) i Rusije. Projekt se odnosi na strujanje na Spitzbergu i ostalim polarnim otocima s planinama. To je rezultiralo kasnije npr. radom: http://bib.irb.hr/prikazi-rad?&rad=374344
