Abstract

We present a study of the impact of short term variations (up to hours) of the physical conditions at a site on the atmospheric seeing conditions. This study includes ground layer seeing estimates through the use of computational fluid dynamics (CFD) simulations as well as observational data originating from the site testing program of the Thirty-Meter-Telescope (TMT). We discuss a case scenario and compare this and general trends to the CFD predictions.
