Sprung, D. Sucher, E. Eisele, C. Seiffer, D. Stein, K. Contributor van Eijk, A.M.J. (editor) Davis C. (editor) Hammel, S.M. (editor) Publication year 2016 Abstract Optical turbulence for over-water conditions was investigated in a long-term experiment over False Bay near Cape Town, South Africa. A sonic anemometer and two boundary-layer scintillometers were deployed to access in-situ turbulence as well as the integrated turbulence over two 1.8 and 8.7 km paths. Statistical analysis reveals spatial temporal variations of the turbulence conditions over False Bay, which might be related to differences in the atmospheric conditions and/or the surface (water) temperatures. An analysis in terms of mechanical and thermal forcing reveals that the latter factor is more dominant in determining the turbulence strength. © 2016 SPIE.
