抽象的。研究了风速对远海地区0.55 μm气溶胶光学厚度的影响。偏远海域是由卫星观测的AOD和ECMWF的风向相结合来定义的。根据我们的定义，许多海洋区域不能被视为遥远的海洋区域，因为来自大陆的气溶胶的长距离传输。在风速范围为0-20 ms−1的偏远海洋区域发现了高度相关的线性关系。高风速下气溶胶光学厚度的增强主要是由于海盐气溶胶产生量的增加。
Abstract. The effect of wind speed on aerosol optical depth (AOD) at 0.55 μm over remote ocean regions is investigated. Remote ocean regions are defined by the combination of AOD from satellite observation and wind direction from ECMWF. According to our definition, many ocean regions cannot be taken as remote ocean regions due to long-range transportation of aerosol from continents. Highly correlated linear relationships are found in remote ocean regions with a wind speed range of 0–20 ms−1. The enhancement of AOD at high wind speed is explained as the increase of sea salt aerosol production.
