Description :
The aim of this paper is the characterisation of the mountain lee wave arising in the Beskid Niski Mts. (Polish Carpathians). On the basis of Podkarpacki Aeroclub documentation of mountain lee wave gliding campaigns, it has been found that the phenomenon occurs most often in the cold half of a year (particularly in November), mostly with southerly or south westerly air advection, and more cyclonic than anticyclonic cases of atmospheric circulation. The minimum wind speed required to give rise to a mountain lee wave in the Beskid Niski Mts. is 7 m.s-1, not necessarily in a stable atmospheric circulation. The paper presents the differences between the properties of the mountain lee wave in the Beskid Niski Mts., and the other major mountain ranges within the Polish Carpathians, especially the Tatra Mts. The conclusions are of practical meaning for gliding. – (BJ)
