Intense wind events cause material damage and expose human life and different ecosystems in situations of vulnerability. The intensity and direction of the wind play an important role in different disciplines: for example, they influence airport activity, determine the use of wind energy, intervene in agricultural production, impact on the spread of forest fires and therefore on air quality. Although some climate studies and climate variability of wind show a decrease in the average daily and annual intensity in recent years both in Argentina and in other regions of the world (Baldo and Cerne, 2018; Cuneo et al., 2019; Vautard, et al., 2010), significant positive trends in both surface and upper wind speeds are also observed in southern Argentina (Merino, 2022). For the reasons mentioned above, among others, it is very important to continue with studies referring to the wind variable at the national level. The objective of this work is to carry out a preliminary characterization of the wind at 10 m for different time scales in the aeronautical meteorological station of Ezeiza (SAEZ) during the period 2009-2019 and compare the results with the climatological period 1981-2010. The results found show that the lower intensities of the average daily winds and daily maximums for both the 2009-2019 series and the climatological series are recorded during the autumn and winter months and it is observed, in general, that the maximum daily winds double the intensity of the daily average winds. In addition, the monthly average winds of the period 2009-2019 show a clear tendency to decrease the intensity and amplitude between maximum and minimum values compared to the climatological data.
