英文摘要	Assessing change in daily maximum wind speed and its likely causes is crucial for many applications such as wind power generation and wind disaster risk governance. Multidecadal variability of observed near-surface daily maximum wind speed (DMWS) from 778 stations over China is analyzed for 1975-2016. A robust homogenization protocol using the R package Climatol was applied to the DMWS observations. The homogenized dataset displayed a significant (p, 0.05) declining trend of 20.038 m s21 decade21 for all China annually, with decreases in winter (20.355 m s21 decade21, p, 0.05) and autumn (20.108 m s21 decade21; p, 0.05) and increases in summer (10.272 m s21 decade21, p, 0.05) along with a weak recovery in spring (10.032 m s21 decade21; p. 0.10); that is, DMWS declined during the cold semester (October-March) and increased during the warm semester (April-September). Correlation analysis of the Arctic Oscillation, the Southern Oscillation, and the west Pacific modes exhibited significant correlation with DMWS variability, unveiling their complementarity in modulating DMWS. Further, we explored potential physical processes relating to the atmospheric circulation changes and their impacts on DMWS and found that 1) overall weakened horizontal airflow [large-scale mean horizontal pressure gradient (from 20.24 to 10.02 hPa decade21) and geostrophic wind speed (from 20.6 to 10.6 m s21 decade21)], 2) widely decreased atmospheric vertical momentum transport [atmospheric stratification thermal instability (from 23 to 11.5 decade21) and vertical wind shear (from 20.4 to 10.2 m s21 decade21)], and 3) decreased extratropical cyclones frequency (from 20.3 to 0 month decade21) are likely causes of DMWS change. © 2020 American Meteorological Society.
