Finally, several local-scale influences of the complex coastal shape appeared in our measurements, e.g., wind fanning in the lee of the isthmus and airflow skirting around the peninsula forehand.Ībbs DJ (1986) Sea-breeze interactions along a concave coastline in Southern Australia: observations and numerical modeling study. ![]() The breeze onset was shown to fail several times under the influence of weak non-thermal events, e.g., the passage of an occluded front or clouds or an excess of convection. As the surface wind speed was much larger than the synoptic wind speed, such a case we have designated as a “synoptic breeze”. In offshore synoptic-flow conditions (quadrants 1 and 2), the clockwise rotation of the surface flow had a very large amplitude, reaching up to 360 \(^\)) around the synoptic wind direction. ![]() Our analysis focuses on the patterns of lower-altitude wind direction and speed around the bay and over the water basin, and the temporal variations during the periods of the breeze onset, establishment and thermal reinforcement. Synoptic data and local measurements are analyzed here from the point of view of both micrometeorologists and competition skippers, testing in particular the empirical rules of breeze veering and backing according to the wind direction with respect to the coastline orientation at the mesoscale (the quadrant theory). Micrometeorological variables were recorded at three shore sites around the bay using turbulence sensors on 10–30-m high masts, on four instrumented catamarans at selected sites within the bay, and at a fourth shore site with a Sodar. ![]() The measurements were taken during the 2 weeks of 16–28 June 2006. The Quiberon 2006 experiment was launched to document the onset and development of land and sea breezes over a semi-circular coastal bay propitious to inshore sailing competitions. ![]()
