| Abstract: |
| The 21st century "Maritime Silk Road" strategy is a significant part of the belt and road initiatives of China. The cognition and investigation of ocean environment is essential and necessary in these regions which will provide scientific reference for many fields such as navigation, ocean engineering, and disaster prevent and reduction. A high-resolution cross-calibrated multi-platform wind product is used to analyze gales over the Maritime Silk Road. The yearly mean speed and space distribution of gale, and the frequencies and trends of gale and extreme wind speed are analyzed. The results show that relatively high pools of gale are mainly located in the waters of the Arabian Sea, the Somali Sea, Indo-China Peninsula sea area, and Bay of Bengal in the summer. The gale frequency of the Somali Sea is more than 90%. Overall, the gale days increase year by year in the majority of the South China Sea and the northern Indian Ocean, especially in the autumn and the winter. |

| 21世纪海上丝绸之路战略是中国“一带一路倡议”的重要组成部分。海上丝绸之路海域海洋环境的认知和调查是必不可少的，可以为航海、海洋工程、防灾减灾等领域提供科学依据。本文使用高分辨率多平台交叉定标风产品（CCMP）分析海上丝绸之路海域的大风特性。分析了大风天气的年平均速度、空间分布，以及风速和极端风速的频率和趋势。结果表明，在夏季，相对较高的大风场主要分布在阿拉伯海、索马里海、印度支那半岛海域和孟加拉湾海域。索马里海的大风频率超过90%。总体而言，南海大部分区域和北印度洋，大风天逐年增加，增加趋势在秋冬季节尤为明显。 |
