  We analyze the monthly average wind velocity at about 12 km above sea level,
between 1980 to 1995, for San Pedro Martir, Mauna Kea, another existing
observatorie and some sites of interest. We compare the results obtained from
two different data sets, the GGUAS and NCEP. Our results show that San Pedro
Martir and Mauna Kea are comparable and are amongst the most suitable sites to
apply slow wavefront corrugation correction techniques
