Abstract
This study analyzes the extreme wind speed characteristics over the Tibetan Plateau using ERA5 reanalysis data from 2014 to 2023. The spatial distribution of extreme wind speeds reveals that the northern and central regions experience the highest wind speeds, with maximum values exceeding 15 m/s, driven primarily by the influence of the westerly jet stream. In contrast, the southern plateau, particularly near the Himalayas, shows much lower extreme wind speeds, typically below 5 m/s, due to the Himalayan barrier and the stabilizing effect of the Asian summer monsoon. Extreme wind speeds exhibit strong seasonal variability, peaking in winter and early spring when the westerlies are strongest, and reaching their lowest values in summer due to the monsoon. These findings offer important insights into the risks associated with extreme wind events and their potential impact on infrastructure, renewable energy development, and climate resilience strategies in the region.
