Quality of wind prediction is of great importance since a good wind forecast allows the prediction of available wind power, improving the penetration of renewable energies into the energy market. This work shows the application of a technique to improve wind forecasting. The study area is southern Italy.

Magnetic reconnection is a key process in space and laboratory plasmas which transfers energies through the magnetic field topology change. The topology change in this process takes place in a small scale region called the electron diffusion region (EDR). In this paper, using high-resolution fully kinetic simulations, we successfully obtained the firm scaling laws of spatial dimensions of the EDR. The obtained scalings allow us to precisely predict observable dimensions of the EDR in real space.

We investigated the zonal and meridional momentum flux at 86–94 km using two nearly identical sets of meteor radar observation data at Koto Tabang and Biak in Indonesia (both at the Equator) by applying a method proposed by Hocking (2005). The observed zonal momentum flux at the two sites agreed reasonably well at 86, 90, and 94 km during the observation periods when the data acquisition rate was large enough. Our results suggest the usefulness of the Hocking method.
