The most significant feature of global land surface wind speed (SWS) recently has been the long-term weakening trend since the 1960s, that is, the phenomenon known as global terrestrial stilling. Many studies have found that stilling is widespread worldwide. It has seriously affected the ecological environment and social economy, especially restricting the sustainable development of the wind energy industry. It is found that the stilling reversed around 2010, and global SWS is strengthening.
