Oct 01, 2020 · FLOOD warnings have been issued for almost the entire country this weekend as Storm Alex is set to bring 90mph gales and heavy rain. Yellow weather alerts will be in place for most of the UK … With the large-scale development of wind energy, wind power forecasting plays a key role in power dispatching in the electric power grid, as well as in the operation and maintenance of wind farms. The most important technology for wind power forecasting is forecasting wind speed. The current mainstream methods for wind speed forecasting involve the combination of mesoscale numerical ... Species distribution models (SDMs) are numerical tools that combine observations of species occurrence or abundance with environmental estimates. They are used to gain ecological and evolutionary insights and to predict distributions across landscapes, sometimes requiring extrapolation in space and time. SDMs are now widely used across terrestrial, freshwater, and marine realms. Differences in ... Oct 01, 2019 · The choice of a suitable theoretical wind speed distribution is an important prerequisite for accurate wind energy yield estimation. In this review, 46 studies published 2010–2018, which compared the goodness-of-fit of different theoretical parametric distributions, were evaluated. Here, we demonstrate a coupled convolutional neural network and recurrent neural network architecture that extracts the wind speed encoded in visually recorded flow-structure interactions of a flag and tree in naturally occurring wind. Predictions for wind speeds ranging from 0.75-11 m/s showed agreement with measurements from a cup anemometer ... The ' wind speed probability ' graphical product gives the current likelihood that a specific point on a map will be struck by hurricane (74 mph) and/or by tropical storm strength (39mph) winds during the next 5 days. The product is designed for clarity and usefulness of information. One year wind speed data in 10 minute resolution are first fitted by two Weibull distribution parameters and then transformation to normal distribution is done for prediction calculation purposes. Second, section 3 of the chapter models wind speed patterns by decomposing it in different time scales / frequency bands using the Fourier Transform.
