The Moroccan energy system is highly dependent on external energy markets. Therefore, the current renewable energy strategy is focused on deployment of large-scale renewable technology projects. Morocco has abundant wind resources. Estimations made by developing organizations in Morocco which quantify the economic and technical potential of wind energy in Morocco with the amount of 26 GW. Aims: This study aims to determine the first approximation in the areas of Morocco which are prospective for the development of wind energy in period for 2020-2050. Place and Duration of Study: Odessa State Environmental University between September 2017 to March 2018. Methodology: In this particular study the user data from regional climate modeling with a high spatial resolution of the project CORDEX has been estimated. Simulations of local climate models provide opportunities for a better understanding of atmospheric processes in the region and their possible future change. In this study use of regional climate models simulate the RCP of 4.5 scenarios for the Africa region, which is presented in a rectangular coordinate system with a spatial resolution of ≈ 44 km. As a result of the regional climate model calculation, the mean monthly Near-Surface Wind Speed (10-meter Wind Speed) values from 2020-2050 for the territory of Morocco.

Dry wind is a widespread dangerous phenomenon, which reduces the yield of crops in Ukraine. The aim of this study is to determine the conditions of the atmospheric circulation leading to the formation of dry winds in August 2010 and to determine the effect of these conditions on the distribution of dry winds in Ukraine during this period. Daily observations at 24 meteorological stations for the period from 31 July to 31 August 2010 were used, as the initial dataset. To define the location where the formation of initial dry wind air mass begins, backward trajectories for the previous movement patterns of air particles were constructed for period of a 120 hours (5 days) for the following heights: earth surface (0 m nominal), 1500 m and 3000 m for stations where the phenomenon was observed. During this period dry winds were observed in different parts of Ukraine, and the longest multi-day dry wind in period from 1995-2015 was observed at Mariupol station, from 31July 2010 to 20 August 2010, lasting 21 days. In first half of August 2010, air masses came from regions of northwestern Kazakhstan, the Ural Mountains, and the east and northeast of European Russia. After a blocking anticyclone over European Russia was dissipated, the baric field was reorganized, and territory of Ukraine was under the influence of the western air masses. After the development of an anticyclone over Central Europe at each heights, air masses Original Research Article
