Review of Research on Wind Resources Changes in China and in the World |
|
|
Abstract: Since the 20th century, with the rapid growth of the world economy, the energy demand has multiplied and energy industries are in a process of massive development with respect to wind resources. The wind energy, clean, renewable, and abundant in nature, offers pollution-free electricity, as the fastest growing energy approach in the world. Studies on wind climate and the change of wind resources are widely carried out. The observations of wind speeds during the 20th century indicate that: ① the wind speed sees an increasing trend in high latitudes and a declining trend in low latitudes of both hemispheres; ② the annual mean wind speed sees an obviously declining trend over broad areas of China;
③ urbanization, the change of anemometers, or the relocation of stations in China are factors that might be responsible for the decreasing trend of mean wind speeds. The decreasing trend in China is mainly due to the changes of atmospheric circulation. Furthermore, the prediction of wind and wind energy in the 21st century shows that as a result of increasing anthropogenic emissions and global warming, the annual and winter mean wind speeds and wind power densities are likely to reduce. The changes of summer mean wind speeds and wind power densities see great uncertainties. At present, the studies on the prediction of surface wind speed by the climate models and simulations have just started, and much work has to be done before some relatively reliable conclusions might be reached.
