Webb1 juni 2024 · In the present paper, the representation of katabatic flow structures over Greenland in a regional climate model is investigated using in situ aircraft data. The area of the Greenland ice sheet is about 1.75 × 10 6 km², and its slopes are associated with katabatic winds, particularly during winter ( Figure 1 ).

Katabatic Flow Mechanisms on a Low-Angle Slope
WebbA time-dependent 2-dimensional model of pure katabatic flow over a simple finite-length slope is described. This numerical model, based on a turbulent kinetic energy closure, accounts for the effects of radiative cooling and turbulent friction at the surface, and entrainment of air aloft from a quiescent stably stratified ambient atmosphere.
