Figure 14. Predictions of cross-mountain (color, m/s) and vertical winds from Clark's mountain wave model over Boulder, CO at 1450 UTC 9 December 1992 showing a strong mountain wave with wave breaking at 10-12 km MSL over the mountain crest. The domain shown is an inner nest of a 3-D simulation initialized with analyzed fields from the MAPS data assimilation system. Time-dependent lateral boundary conditions are also used from MAPS, which is updated every 3h.
