One important large telescope design study area is the dynamic image degradation caused by wind forces upon various telescope structures and optical elements. The need to establish rapid thermal equilibration with the observatory environment further complicates the wind exposure problem. On the other hand, a telescope deeply embedded in a large enclosure is subject to dome induced seeing difficulties unless great care is used to eliminate any thermal differences among telescope structure, optics, dome interior and inside and outside air. While dome seeing is outside the scope of this paper, it should not be neglected in the consideration of enclosure design because wind protection and seeing are inexorably coupled.
