Abstract
The purpose of this study is to developed a wind spectrum model for the site of the new Mexican Optical-Infrared Telescope (TIM) to be installed at the Sierra of San Pedro Mártir. This model will be useful in the study and design of the structure and building that will contain the telescope. This paper summarizes the results of our initial analysis of selected wind data obtained at the site with a sampling frequency of 40 Hz. For each data set we calculated the power spectral density. A power law ∝ f-γ for the high frequency part of the spectrum was fitted and the spectral index γ was found to be in the range of 0.625 to 0.969, and to depend on the wind direction. The frequency for the maximum of the spectrum lies in the range of 0.008 to 0.017 Hz. These studies should be repeated once the building is installed at the site due to changes in the site topography.
