| Summary: | Aim. To analyse seasonal changes in the frequency characteristics of wind speed and direction in coastal Dagestan, namely the urban districts of the cities of Makhachkala and Derbent, from the point of view of wind power potential.Material and Methods. The research was based on time series of wind speed and direction for the period 2011-2018, obtained as a result of observations at the Makhachkala and Derbent weather stations. As a mathematical research tool, a continuous wavelet transform with a complex Morlet wavelet function was used.Results. According to the results of analysis, it was found that the main frequency of fluctuations in the time series is one day and one-day periodicity in the time series has pronounced seasonal changes. Also, differences in seasonal changes of one-day periodicity for wind speed and direction between the regions of Makhachkala and Derbent were established and described.Conclusion. The parameters considered in assessing seasonal changes in the dynamics of wind speed and direction can be used as additional parameters for the classification and clustering of regions to identify the best areas of wind power potential. |
