Abstract:Data collected during the french lsquoVOVES-1977rsquo experiment are used for the determination of the functionsA(mgr) andB(mgr) of the stability parameter mgr. It is found that, although pertaining to different geographic conditions, they lead to the same kind of dependency ofA andB upon mgr as found previously considered data. The influence of baroclinicity onA andB is also studied and it is found in that, statistically, consideration of this parameter does not lead either to a decrease of the large scatter of experimental points or to a significant improvement of the similarity theory. It is also shown that a satisfactory estimation of the surface geostrophic wind can be made from the network of meteorological stations, to compute such functions.
