Turkish radiosonde data obtained at the meteorological stations in Istanbul, Ankara, and Izmir have been analysed in order to study the winds between 850 hPa and 300 hPa pressure levels between 1970 and 1984. The monthly mean values of both the zonal (ū) and the meridional (v̄) wind velocity components, their variances, σ 2 u and σ 2 v , and the monthly mean values of wind direction, α, were statistically determined. The constancy, Q , of the winds was then computed by taking the ratio of the monthly mean resultant wind speed (V̄ t ) and the monthly mean scalar wind speed (V̄ s ). The results were interpreted by taking local wind patterns into consideration.
