Wind plays a crucial role in shaping climatic and environmental conditions; however, its spatial and temporal variabilities over land remain poorly understood. This study utilizes combined datasets from multiple satellite platforms to examine the spatial patterns and temporal trends of wind speed over land during the past 30 years (1988–2017). The results demonstrate a significantly increasing trend in global wind speed, with variations on both annual and monthly scales. Spatially, wind speeds are lower in low-latitude regions, particularly in the tropics. High wind speeds primarily occur in mid- to high-latitude regions, with the highest speeds observed in the Arctic. Temporally, wind speed trends are characterized by an increase in low-speed winds and decrease in high-speed winds. Overall, wind speed shows a significant correlation with temperature in the Amazon, northern Europe, and central Asia. Negative wind–temperature correlation is confined to small regions in central North America and northern Africa. The findings of this study help clarify wind trends, providing valuable insights for future research on global climate and environmental change.
