Large-Eddy Simulation #42: 12.8 x 12.8 km Homogeneous CBL
Same as LES#40 except domain size is twice as large in the
horizontal. The purpose of this run was a simple check to see if the
domain size had an effect on the coherent structures (spokes, etc.)
produced in LES#40. The purpose of LES#40 was to simulate a
homogeneous CBL and compare the results with Nieuwstadt et al. (1993).
Every two points of LES#42 model output was averaged in order to reduce
size of the data set.
LES RUN #42: 160 m HORIZONTAL, 50 m VERTICAL RESOLUTION
Domain size 80x80x50 grid-points.

This domain is 12.8 km (east-west) by 12.8 km (north-south) wide.
The horizontal slice of w shown above (200 m above the surface)
contains coherent polygonal spokes and cells that have been observed in
other LESs (for example, see Schmidt and Schumann, 1989, JFM, 511-562)
and our Volume Imaging Lidar data (10 Jan 98 14:16-14:57 Z and 13 Jan
98 16:25-16:30 Z).
