Book excerpt: The design and operation of remotely piloted aircraft at low-Reynolds numbers an at extremely low altitudes above the ocean requires low level wind input data. Surface winds and gusts are known to have a strong influence on the operation of aircraft near the surface and can cause serious control problems. In general, cross winds, wind shear and gusts encountered by low-flying aircraft pose significant problems in their operation. Although numerous experimental studies have been made in the surface layer and boundary layer over the ocean, the ability to apply the currently available information to the design and operation of aircraft is limited. This report reviews the current experimental knowledge of the marine atmospheric surface layer and discusses the nature and quality of the reported data as well as their applicability as input to the design and operation of low-flying aircraft.
