In order to highlight the wind characteristics in Crisul Repede drainage area we used the data collected between 1970 – 2008 from the 5 meteorological stations within Crisul Repede drainage area, namely: Oradea meteorological station (136m), Sacueni meteorological station (125m), Borod meteorological station (333m), Huedin meteorological station (560m), and Stana de Vale meteorological station (1108m). In order to carry-out this research study we employed both a series of traditional research models as well as a series of modern means and models. The main methods used in the current research are the following: analysis method, deduction method, induction method, comparative and statistics-mathematics methods and graphs, and cartographical method. The comparative method highlights, through comparing the parameters of aeolian regime, the weather fluctuation withinCrisul Repede drainage area, the differences occurring function of the nature of active surface. The data collected from the database of National Meteorological Administration (ANM) were computed by means of statistics-mathematics. The outcome obtained through mathematics – statistics methods were subsequently translated into graphs in order to highlight clearly the wind unsteadiness (variations) in time.  The aim of the current paper is to research the wind’ direction and speed in the within Crisul Repede drainage area. On soil proximity, wind presents short-term direction and speed fluctuations soil proximate surfaces; these are strongly dependent on the value of baric horizontal gradient, the local conditions, especially the orography, etc.  The relief influences the wind features by fragmentation level, through summits or corridors’ orientation, by altitude, and mountain massifs expansion. The wind is channelled into Aeolian depression (hollows) channels thus leading to boosting wind speed and, at the same time, to changing its direction of displacement. The Crisul Repede Valley is East-West oriented, and thus it stimulates the wind air flows creation on this direction. In highlands, the dominant air flow directions are different as against the plains ones, and function of meteorological stations in the local relief, they can protected or in some sectors.  In urban areas, the wind elements are influenced both by soil characteristics and urban constructions, by means of building heights, streets’ direction and largeness.  The Aeolian data have a practical importance, as they are used in several fields of activity: weather forecasts, setting industrial building locations, city planning, air and maritime traffic, energy sector, agriculture, constructions, etc.
