Quantifying the latitudinal representivity of in situ solar wind observations [PDF]
, 2020 Advanced space-weather forecasting relies on the ability to accurately predict near-Earth solar wind conditions. For this purpose, physics-based, global numerical models of the solar wind are initialized with photospheric magnetic field and coronagraph ...

Predictive control of wind turbines by considering wind speed forecasting techniques [PDF]
, 2009 A wind turbine system is operated such that the points of wind rotor curve and electrical generator curve coincide. In order to obtain maximum power output of a wind turbine generator system, it is necessary to drive the wind turbine at an optimal rotor ...

Wind turbine condition assessment through power curve copula modeling [PDF]
, 2012 Power curves constructed from wind speed and active power output measurements provide an established method of analyzing wind turbine performance. In this paper it is proposed that operational data from wind turbines are used to estimate bivariate ...

Uncovering wind turbine properties through two-dimensional stochastic modeling of wind dynamics
, 2013 Using a method for stochastic data analysis, borrowed from statistical physics, we analyze synthetic data from a Markov chain model that reproduces measurements of wind speed and power production in a wind park in Portugal.

Wind speed vertical distribution at Mt. Graham
, 2010 The characterization of the wind speed vertical distribution V(h) is fundamental for an astronomical site for many different reasons: (1) the wind speed shear contributes to trigger optical turbulence in the whole troposphere, (2) a few of the ...

Numerical Simulation of Hot Accretion Flows (III): Revisiting wind properties using trajectory approach [PDF]
, 2014 Previous MHD simulations have shown that wind must exist in black hole hot accretion flows. In this paper, we continue our study by investigating the detailed properties of wind, such as mass flux and poloidal speed, and the mechanism of wind production.

Wind speed forecasting at different time scales: a non parametric approach
, 2013 The prediction of wind speed is one of the most important aspects when dealing with renewable energy. In this paper we show a new nonparametric model, based on semi-Markov chains, to predict wind speed.

A cyclo-stationary complex multichannel wiener filter for the prediction of wind speed and direction [PDF]
, 2013 This paper develops a linear predictor for application to wind speed and direction forecasting in time and across different sites. The wind speed and direction are modelled via the magnitude and phase of a complex-valued time-series.
