Abstract
Based on observational data of meteorological stations and reanalysis data, seasonal-daily values of total radiation and wind speed in the Russian sector of the Arctic were estimated over the time interval 1987-2016. Possible climate change effect was also considered. It was revealed that the total solar energy flux reached the peak values in June (7-8 kW h/m2); moreover, its increase was noted in summer months, when moving from west to east. The median values of wind speed in the region were 4-6 m/s and they were not significantly changed during a year. Minimal values of wind speed increased from winter to summer, and the maximal ones decreased. When moving from west to east, as well as from north to south a decrease in median and extreme wind speed values was observed. It was established that the frequency of wind speed less than 1.5 m/s, on average in the region, was 9%, and it varied from 4 to 20%, and the duration of windless periods did not exceed 3 hours (p = 95%). The probability of appearance of intervals with wind speed less than 1.5 m/s decreased with an increase in the length of these time intervals according to the exponential distribution law. Thus, a joint usage of solar and wind energy potential in the northern regions of Russia gives rise to all prerequisites in accelerated development of renewable energy sources in the Russian Arctic.
