A black blizzard, though, isn't actually a blizzard—it's an extreme dust storm.

然而，黑色的暴风雪实际上并不是真正的暴风雪，它是一场极端恶劣的沙尘暴。

Of course, the black blizzards of the 1930s weren't as bad as the planet-covering dust storms that the planet Mars gets every couple years.

当然，20世纪30年代的黑色暴风雪并不像火星上每隔几年就会发生的覆盖整个星球的沙尘暴那么严重。
