Spatio-temporal characteristic of the wind speed Regime in the territory of the Syunik marz of the republic of Armenia

The article discusses the features of the main characteristics of wind speed in the territory of the Syunik marz of the Republic of Armenia; the statistical characteristics of the wind are obtained. For analysis, we used the data of the Hydrometservice of the Republic of Armenia for a period of 50 years and more (1966-2018) at 7 weather stations. An analysis of the spatial change in the characteristics of the wind speed showed a variety due to the roughness of the terrain, where the terrain has a great influence on the distribution of wind speed characteristics.

Based on the statistical analyses, the norms of monthly and annual wind speeds are determined; the spatial and temporal variability of their studied characteristics is analyzed. To calculate the annual value of the wind speed of unexplored areas, correlation dependencies between the value of wind speed and elevation are obtained. Built a map of the distribution of the annual value of the wind speed.

The performed analysis of the spatial variation of the velocity characteristics wind regime showed a variety due to the ruggedness areas where the relief has a great influence on the distribution wind speed characteristics. Average annual wind speed at the study area ranges from 1.1 to 7.7 m/s: the largest average wind speeds are observed at Sisian and Vorotan passes, especially in summer, the lowest average wind speeds are in Meghri, especially in autumn and winter. The wind speed increases with height. Vertical the gradient of the average annual wind speed in the lower zone is –0.25 m/s / 100 m, and in the upper zone - 0.75 m/s / 100 m. On the territory of Syunik the diurnal variation of the wind speed is well pronounced, and the annual variation differs ambiguous patterns. In Syunik marz, the wind speed is during the day it grows in the daytime and maximum in the warm afternoon time, and from midnight to early morning, the wind speed decreases and reaches a minimum.

To assess the dynamics of changes in wind speed, three periods were allocated (1966-1985, 1986-2000, 2001-2018). Both by months and by year there is a non-uniform dynamics of changes in the average values of the speed wind.

The results can be used in planning the development of wind energy in the Syunik marz, the development of wind energy cadasters of territories, climate services for sectors of the economy, adjustment of building standards.
