Short summary
As wind turbines grow to unprecedented sizes, ensuring their reliability requires advanced testing. We reviewed the current state of wind tunnel experiments, examining how scaled physical models are evaluated for wind flow, flexibility, and noise. We conclude that while laboratory testing remains essential, it is most powerful when integrated with computer simulations and real-world data. This combined approach will ultimately drive the design of more efficient and sustainable wind energy.

Starting from existing offshore projects in the Mediterranean Sea, we utilized the CERRA (Copernicus European Regional Reanalysis) dataset to analyze historical wind data and applied a genetic algorithm to propose a preliminary layout for a large number of farms. A significant part of our study involves the use of Monte Carlo simulations to project future energy scenarios. These simulations consider various factors, including technical challenges, wind patterns, turbine characteristics, and array efficiency affected by wake effects.

Simultaneous heatwaves or cold spells in remote geographical regions have potentially far-reaching impacts on society and the environment. Despite this, we have little knowledge of when and where these extreme events have occurred in the past decades. In this paper, we present a summary of past simultaneous heatwaves or cold spells and provide a computer program to enable other researchers to study them.

Short summary
Planetary Rossby waves are created by topography and evolve in time. In this work, an analytical solution of this classical problem is proposed under the approximation of linear wave dynamics. The theory is able to describe reasonably well the evolution of the perturbation and compares well with full nonlinear simulations. Several relevant cases with single and double zonal jets are assessed with the theoretical framework

Short summary
We conducted wind tunnel experiments on nine wind turbine models and measured their power while intentionally yawing them away from the wind direction. By testing a broad range of yaw-angle combinations, we found that this method can increase the total power output by up to 5.3%. We also observed how different columns of turbines respond uniquely to these changes and how wind speed affects the overall improvement. Our findings could be useful in developing more accurate wind farm control models.
