Features of the Regime of Wind Speed Climatic Characteristics in the Syunik Marz Area

Abstract

The purpose is to study the features of the regime of climatic characteristics of wind speed in the Syunik marz area of the Republic of Armenia is an urgent task, especially in connection with the fact that the Armenian economy significantly dependent on external energy inputs. And wind power can be used as a source of alternative energy. The article analyzes and evaluates the patterns of the regime of wind speed, their territorial and temporal distribution, daily and intra-year course, the trend of interannual changes in the study area. Also the characteristic of strong winds and calms is given. 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. It was revealed that a well-defined diurnal and varied annual course is observed in the Syunik marz area. The diversity of the annual course of wind speed due to the terrain. Average annual rate wind is 1.1-7.7 m/s, and the annual maximum wind speed is 18-48 m/s. The highest wind speeds are observed at the Sisian and Vorotan passes. With height, wind speed rises. The correlation between the annual average wind speed in the studied area and the height of the place has been revealed. The values can be used to study the wind speed regime of unexplored and little studied areas. In the marz for the period 2011-2018 basically, there is a tendency for a decrease in wind speed compared to the period from 1966-1985. The analysis of the spatial variation of the wind speed regime characteristics showed a diversity due to the ruggedness terrain where the terrain has a large impact on the distribution wind speed characteristics. The results can be used in planning the development of wind energy in the Syunik marz area, the development of wind energy cadastres of areas, climate services for sectors of the economy, adjustment of building standards.
