The basic climatological pattern and recent trends in daily maximum wind speed (DMWS) for the region 47.5degrees-65degreesN and 12.5degreesW-22.5degreesE are studied using gamma distributions within a generalized linear model. Between 1958 and 1998, DMWS has increased over the ocean in winter but...
fluctuations from wind farms, the power spectral density of the wind speed in a single point, and the coherence between two points in the same height but with different horizontal coordinates are estimated based on wind measurements on Ris's test station for large wind turbines in Hvsre, ...
Vegetation coverage dominated the decline in wind erosion in a number of areas, but areas with severe wind erosion were dominated by wind speed. Furthermore, wind speed in the spring was the dominant factor driving the decline in wind erosion across the Horqin Sandy Land. Major wind erosion ...
Being able to convert knots to miles per hour (and vice versa) is an important skill in both meteorology and navigation. When converting between the two, keep in mind that a knot will look like a lower numerical wind speed than a mile per hour. One trick to remembering this is to think...
The probability density function (PDF) of wind speed is important in numerous wind energy applications. A large number of studies have been published in scientific literature related to renewable energies that propose the use of a variety of PDFs to describe wind speed frequency distributions. In ...
This paper analyses wind speed and electricity demand correlation to determine the ability of wind turbine generators to meet electricity demand in the Australian National Electricity Market (NEM) without the aid of energy storage. With the proposed increases in the number of windfarms to meet the ...
Modifying the duct diameter alone has limited influence. However, combining a larger duct diameter d0 = 1.5D with fillets with r/d0 = 0.4, can yield up to 78% increase in average wind speed and 650% in wind power density. Findings indicate that the dimensionless wind speed in the duct (...
In this paper the wind speed forecasting in the Isla de Cedros in Baja California, in the Cerro de la Virgen in Zacatecas and in Holbox in Quintana Roo is presented. The time series utilized are average hourly wind speed data obtained directly from the measurements realized in the different ...
