Mesoscale Modelling of flow response to Greenland

Description

The mesoscale atmospheric flow response to Greenland is difficult to predict. Flow over and around Greenland is affected by (i) the large and very steep elevation change between the coastal margins and the central plateau (~3000m), (ii) the combination of very rough surfaces (roughness length zo~1-10m) and jagged mountains around the coasts, (iii) the strong katabatic flows from the plateau down to the coasts (van den Broeke and Gallee 1996), (iv) the presence of the semi-permanent Icelandic Low, and (v) air-sea-ice interaction processes (Scorer 1988).
