Wind is the most dynamic variable influencing the behavior of grassfires.Wind speedvaries widely over short time periods as well as with height above the ground (Finnigan, 2000). For the purposes of predicting rate of spread it is necessary to specify the height at which the wind is measured...
Wind energy, as a renewable energy source, offers the advantage of clean and pollution-free power generation. Its abundant resources have positioned wind power as the fastest-growing and most widely adopted method of electricity generation. Wind speed st
In particular, if the focus falls on short-term wind speeds, data series always show irregular variations on a short time scale, increasing the complexity of modeling short-term wind speeds. Currently, combining different models has become a popular trend in wind speed estimations, and the ...
This model is better adapted to simulate the low frequency electromechanical oscillations over long periods of time (tens of seconds to minutes). In the phasor simulation method, the sinusoidal voltages and currents are replaced by phasor quantities (complex numbers) at the system ...
Long-term weather and climate observatories can be affected by the changing environments in their vicinity, such as the growth of urban areas or changing vegetation. Wind plants can also impact local atmospheric conditions through their wakes, characteri
return periodswindwindstormSpatially dense observations of gust speeds are necessary for various applications, but their availability is limited in space and time. This work presents an approach to help to overcome this problem. The main objective is the generation of synthetic wind gust velocities. ...

Both Glasgow airport and Townhead monitoring sites are in open locations, therefore the wind-speeds recorded at Glasgow airport were anticipated to provide a reasonably reliable indication of relative temporal changes in wind-speed at Townhead. We made passive sampler measurements over 32 discrete ...
In the current study, three types of linear time series models including autoregressive (AR), moving average (MA), and autoregressive moving average (ARMA) were employed to estimate short-term (i.e., daily) and long-term (i.e., monthly) wind speeds. The required data were gathered, ...
