In this paper, the spatio-temporal (multi-channel) linear models, which use temporal and the neighbouring wind speed measurements around the target location, for the best short-term wind speed forecasting are investigated. Multi-channel autoregressive moving average (MARMA) models are formulated in matrix form and efficient linear prediction coefficient estimation techniques are first used and ...

In this study, the analyses of wind farms and corresponding installed power Turkey are conducted. Wind in have been evaluated by considering five different regions. The map is similarly divided into regions, clearly shown on these maps. or capacity each farm shown. So, a total 251 operating, under-constructional, licensed extensively analysed terms their capacities. On other hand, total

Wind affects adversely the cooling tower thermal performance. A field investigation was carried out to study the thermal performance of Heller cooling towers under wind conditions, involving measurement of wind velocity and its direction around the cooling tower, and obtaining water flow rates and temperatures at the cooling tower inlet and outlet. Results show that air suction at the tower top...

In this study, two kinds of numerical methods commonly used for estimating Weibull parameters are reviewed; i.e. the moment and energy trend factor method. Both methods used the coefficient of determination (R2) and root mean square error (RMSE) was compared with failure analysis. The statistical data of two years’ wind speed measurements of Nigde, Turkey, are used to find out the wind energy p...

As wind energy is one of the most important renewable energy sources over the globe, need for increasing safety for this type of energy is gaining importance. Although this sector is not suffering an excessive amount of fatal injury accidents, there are many aspects open for improvements in occupational health and safety management. The construction and operation processes of wind turbines incl...

Wind speed modeling and prediction plays a critical role in wind related engineering studies. However, since the data have random behavior, it is difficult to apply statistical approaches with apriori and deterministic parameters. On the other hand, wind speed data have an important feature; extreme transitions from a wind state to a far different one are rare. Therefore, behavioral modeling is...

This paper tests the hypothesis that Culicoides (Diptera: Ceratopogonidae) species can be propagated by wind over long distances. Movement patterns of midges were inferred indirectly from patterns of the spread of bluetongue outbreaks between farms (using outbreak data from 1999-2001 for Greece, Bulgaria and Turkey) and then matched to concurrent wind patterns. The general methodology was to de...

The power generated by a wind turbine largely depends on the wind speed. During time periods with identical hub-height wind speeds but different shapes to the wind profile, a turbine will produce different amounts of power. This variability may be induced by atmospheric stability, which affects profiles of mean wind speed, direction and turbulence across the rotor disk. Our letter examines turb...

Abstract This study investigates the seasonal climatology of three-dimensional distribution and transport pathways dust aerosols over West Asia (WA). Dust column loading WA exhibits strong seasonality, with markedly high (weak) during summer (winter). The features include (i) reaching up to 500 hPa level between Red Sea (RS) west coast Indian subcontinent (IS); (ii) a slantwise advection 850 70...
