Impact of Wind Direction and Speed on Dusty Days
The direction and speed of winds play an important role in the occurrence of pollutions and dust stormas well as location placement for the establishment of industries and the expansion of cities. Yazd is a dry area of Iran, and constantly exposed to the dust particles in the air; and this in terms of human life and health issues are of special importance. In this paper a day when due to the am...

متن کاملVariability of Wind and Wind Power
The installed capacity for wind power is increasing substantially in response to the worldwide interest in low-emissions power sources and a desire to decrease the dependence on petroleum. The European Union directive 2009/28/EC enforces the mandatory target of a 20 % share of energy from renewable sources in overall Community energy consumption by 2020 and a mandatory 10 % minimum target to be...
متن کاملIn-street wind direction variability in the vicinity of a busy intersection in central London
Numerous urban field observations have been devoted to understanding the characteristics of flow and turbulence in urban street canyons. However, cities comprise complex road networks incorporating not just idealised street canyons, but realistic geometries including intersections. Street intersections are a second basic element of urban geometry that are critical in dispersion processes. They ...
متن کاملModelling Wind for Wind Farm Layout Optimization Using Joint Distribution of Wind Speed and Wind Direction
Reliable wind modelling is of crucial importance for wind farm development. The common practice of using sector-wise Weibull distributions has been found inappropriate for wind farm layout optimization. In this study, we propose a simple and easily implementable method to construct joint distributions of wind speed and wind direction, which is based on the parameters of sector-wise Weibull dist...
