日食不仅仅是天文学上的兴趣，因为它们提供了一个可预测的能源驱动大气和天气系统的短暂减少。自1834年以来，人们一直在测量地表空气温度的变化，并随后研究了风速和风向，最引人注目的是在1900年美国日食期间。这些研究导致了风速和风向变化相关的理论，由于不同的日食产生了不同的影响，这些理论并非没有争议。在这里，这些理论是进一步发展使用从英国日食的观测1999年和2015年和详细的天气预测模型。这表明，日食期间近地面风的影响可能是由于大气层最低部分结构的变化造成的。
Solar eclipses are not of merely astronomical interest, as they provide a predictable transient reduction in the energy source driving the atmosphere and weather systems. Changes in surface air temperature have been measured since 1834 with wind speed and direction subsequently studied, most notably during the 1900 US eclipse. These studies led to theories associating wind speed and direction changes, which, as different eclipse have produced different effects, have not been without controversy. Here, these theories are developed further using observations from the UK eclipses of 1999 and 2015 and detailed weather prediction models. These show that near-surface wind effects during eclipses can result from changes in structure of the lowest part of the atmosphere.
