20世纪30年代，美国经历了上世纪最具破坏性的干旱之一。干旱影响了该国近三分之二的地区以及墨西哥和加拿大的部分地区，并因发生在南部大平原的众多沙尘暴而臭名昭著。在这项研究中，我们提出的模型结果表明，干旱是由异常的热带海面温度在这十年中，大气和陆地表面之间的相互作用增加了其严重性。我们还将20世纪30年代的干旱与20世纪世纪北美的其他干旱进行了对比。
During the 1930s, the United States experienced one of the most devastating droughts of the past century. The drought affected almost two-thirds of the country and parts of Mexico and Canada and was infamous for the numerous dust storms that occurred in the southern Great Plains. In this study, we present model results that indicate that the drought was caused by anomalous tropical sea surface temperatures during that decade and that interactions between the atmosphere and the land surface increased its severity. We also contrast the 1930s drought with other North American droughts of the 20th century.
