Abstract

In recent years, a significant number of observatories and universities have been planning to construct optical and infrared telescopes at the Lenghu site in Qinghai Province due to the site's excellent seeing and clear night sky fraction. Although astronomical performances of the Lenghu site have been reported in detail by numerous papers, there were few reports showing statistics of temperature and wind characteristics in the traditional way required for the design of steel structures of large astronomical telescopes and enclosures, as well as the ventilation and air conditioning systems of these enclosures. This paper aims to present such new statistical data on temperature and wind conditions at the site, which could be helpful to inform and aid in such design decisions at the Lenghu site
