Slovak republic imports around 90 percent of its primary energetic resources that are at the same time poorly diversified because most of them are originated in the Russian Federation. In spite of the significant structural changes in the last two decades the Slovak economy still remains heavily depe...

This paper considers potential changes in storm occurrence and intensity over the western Black Sea through analysis of long term series of wind and wave conditions simulated with relatively high resolution. It is a result of coupling of atmospheric and wave models and spans period of more than 60 years (1948-2008). On the basis of the established methodology of wave climate clustering, wave events capable of producing a noticeable morphological response are separated from the remaining part of the dataset. Furthe...

Knowing wind energy and its features can help programmers in using this clean, free and renewable energy. Iran is located in the west wind region, and the common wind direction is from north-west to south-west in Iran. But in some regions of Iran, due to special regional conditions as well as the synoptic factors of atmosphere, the wind direction is different from the common wind direction in Iran. The wind speed is also higher than the average speed of west winds. Based on the statistics from wind speed and direc...
