黑色风暴事件（英语：Dust Bowl），或称肮脏的三零年代（Dirty Thirties）是1930-1936年（个别地区持续至1940年）期间发生在北美的一系列沙尘暴侵袭事件。由于干旱和持续数十年的农业扩张，对北美大平原原始表土的深度开垦破坏了原本固定土壤、贮存水分的天然草场，以及未有相关防止水土流失的措施 ，风暴来临时卷起沙尘，使得美国和加拿大大草原上的生态以及农业受到了巨大影响。

1930年代的干旱期，由于缺乏自然植被固定土壤，干旱使其转变为沙尘，向东和向南的大风卷起沙尘，形成巨大的深色云雾。情况严重时，云雾所到之处遮天蔽日，能抵达美国东海岸，例如纽约和华盛顿特区等地。多数沙尘抵达大西洋后才逐渐沉降、固定下来。这些巨大的沙尘暴在美国曾被称为“Black Blizzards（黑色风暴）”或“Black Rollers（黑色巨浪）”——风暴袭来时，能见度骤然下降，仅仅只能维持1米左右（几英尺）的能见度。黑色风暴曾影响了约400,000 km²（100,000,000英亩）的广阔地域，灾害的中心区域为德克萨斯州和奥克拉荷马州的走廊地带，以及新墨西哥州、科罗拉多州和堪萨斯州的衔接区域。干旱致使上百万英亩土地荒芜，成百上千人背井离乡。许多家庭（在美国被称为“俄克佬”（Okie），代表那些来自俄克拉荷马的人）被迫迁往加州或其他州，而经济状况却未有太多改观。由于失去土地，他们寄人篱下，往来于农庄间靠替人采摘葡萄或干农活勉强为生。后来美国作家约翰·史坦贝克创作了关于此类人群的小说《人鼠之间》和《愤怒的葡萄》，并在此后获得了普利策奖和诺贝尔文学奖。

The Dust Bowl, also known as the Dirty Thirties, was a period of severe dust storms that greatly damaged the ecology and agriculture of the US and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent wind erosion (the Aeolian processes) caused the phenomenon. The drought came in three waves, 1934, 1936, and 1939–40, but some regions of the high plains experienced drought conditions for as many as eight years. With insufficient understanding of the ecology of the plains, farmers had conducted extensive deep plowing of the virgin topsoil of the Great Plains during the previous decade; this had displaced the native, deep-rooted grasses that normally trapped soil and moisture even during periods of drought and high winds. The rapid mechanization of farm equipment, especially small gasoline tractors, and widespread use of the combine harvester contributed to farmers' decisions to convert arid grassland (much of which received no more than 10 inches (250 mm) of precipitation per year) to cultivated cropland.
