Turbulence structure of the marine atmospheric boundary layer observed during the SEMAPHORE experiment
- Univ. of Toulouse (France). Lab. d`Aerologie
The SEMAPHORE experiment was conducted in the Azores region in 1993 and was devoted to mesoscale studies of oceanic and atmospheric circulations, as well as interactions between oceanic and atmospheric boundary layers. From October 4 to November 17, two instrumented aircraft gathered data. One of the major objectives of SEMAPHORE was to study the coupling between the atmospheric and oceanic boundary layers in the vicinity of an oceanic temperature front. This front, associated with the Azores current, was located south of the Santa Maria Island where the aircraft were based. The aim of this paper is to document the turbulent structure of the atmospheric boundary layer, analyzed from aircraft measurements, for two different meteorological situations.
