“…Compared to SSP2‐4.5, SSP5‐8.5 shows less decline of wind speed over most global land areas except Central and Eastern North America, and Northern Europe (Figures 8a and 8d). The projected decreasing trends in wind speed indicate that terrestrial stilling will continue during the 21st century (Chen et al., 2021). However, there are studies reporting a reversal of wind speed change in the 2010s from observational records (Zeng et al., 2019), urging a comprehensive evaluation of the climate model projections.…”

“…Before proceeding to the next section, it seems appropriate to briefly address the phenomenon of wind stilling. Terrestrial stilling (TS) denotes the decline in wind speed over land in recent decades [63,64]. Although the reasons for TS are not fully understood, it bears some resemblance to the phenomena reviewed here.…”

Wind energy is considered a pillar of the low-carbon energy system of the future. Whereas the side effects and social costs of fossil energy sources (coal, oil and gas), as well as those of nuclear energy, are well-documented and quantified, understanding of the analogous questions with respect to wind energy is far less advanced. However, such understanding is crucial in order to minimize the influence of wind energy on the environment and to compare its social costs with those of conventional energy sources. Here, we summarize the state of knowledge of three side effects of wind energy that have not been convincingly evaluated to date. We focus our analysis on three topics, namely (1) the impact of wind energy on insects; (2) the impact of wind energy on the spatiotemporal distribution of air velocity, temperature, moisture and precipitation in the vicinity of wind parks; and (3) the impact of wind energy on humans through noise emission. For each topic, we formulate open research questions that should be addressed by responsible policy incentives in order to comprehensively assess the social costs of wind energy and to develop wind farms with minimal impact on their environment.

Near-surface wind speed is of great signi cance in many aspects of the human production and living.This study analyses the spatiotemporal characteristics of the near-surface wind speed and wind speed percentiles with meteorological station observations in China from 1979 to 2019. Furthermore, the mechanisms of the wind speed variations are also investigated with ERA-Interim reanalysis dataset.Spatially, the wind speeds in the northern and eastern regions of China are larger than that in the central and southern regions. Seasonally, the wind speed in spring is signi cantly larger than that in the other seasons. The dispersion degree of wind speed in spring is larger than that in the other seasons both spatially and temporally. The near-surface wind speed in China shows signi cantly decreasing trends during 1979-2019, particularly in 1979-1999, but the wind speed trend reversed after 2000. After dividing the wind speed into different percentiles, it recognizes that the decreasing trend of stronger winds are more signi cant than that of weaker winds. The weaker the wind speed, the more signi cant increasing trend after 2000. Therefore, the decreasing wind speed trend before 2000 is mainly caused by the signi cant reduction of strong wind, while the reversal trend after 2000 results from the increase of weak wind. The variations of the wind speed over China attributed to both the U and V wind components, and the variations of zonal wind is closely related to the weakened upper westerly wind eld and the uneven warming between high and low latitudes.
