Experiment models mixed-layer growth over tree-covered terrain, indicating higher closure constants than expected.
The Koorin Experiment offers a unique set of boundary-layer data taken over land at a low latitude (16° 16'S) and over a tree-covered terrain with large roughness (z0 ≅ 0.5 m). These data have been used to predict the rise of the mixed layer using the 'jump' (or 'slab') model formulation recommended by Driedonks and Tennekes (1984). The results show that the closure constant CF for these data is larger than the popular value of 0.2. For predictions of the mixed-layer height at 1500 h and 1800 h the best value of CF was found to be 0.6 and at 1200 h the best value was 0.5. Possible reasons for these large values are discussed.
