Figure 9. Temporal evolution of the mountain wave environment
based on combined wind (isotachs; grey, dashed, m s-1) and virtual
potential temperature (solid, K, [dashed are estimated]) profiles
from 404- and 50-MHz wind profilers with RASS at Platteville,
CO. A 35 m s-1 downslope windstorm occurred in Boulder from
1100-1600 UTC when the cross-mountain winds and static stability
near mountain top (4 km MSL) strengthened, and while the vertical
wind shear above mountain top was very weak, i.e., before the
arrival of the upper-level jet.
