We are grateful to Prof. Dave Whiteman for the interesting discussions on intermittent turbulence, which led to this study. We are also grateful for support from National Science Foundation (NSF) Grant ATM-0645784 (Physical and Dynamic Meteorology Program). Acknowledgement is also made to the National Center for Atmospheric Research, which is sponsored by NSF, for computing time used in this research. The National Elevation Dataset and the National Land Cover Database came from the U.S. Geological Survey. The observational data were downloaded from the T-REX data archive, which is maintained by the National Center for Atmospheric Research's Earth Observation Laboratory.
