Explanation: Could there be a tornado inside another tornado? In general, no. OK, but could there be a tornado inside a wider dust devil? No again, for one reason because tornados comes down from the sky, but dust devils rise up from the ground. What is pictured is a landspout, an unusual type of tornado known to occur on the edge of a violent thunderstorm. The featured landspout was imaged and identified in Kansas, USA, in June 2019 by an experienced storm chaser. The real tornado is in the center, and the outer sheath was possibly created by large dust particles thrown out from the central tornado. So far, the only planet known to create tornados is Earth, although tornado-like activity has been found on the Sun and dust devils are common on Mars.

说明: 龙卷风里头会再套着另一个龙卷风吗？通常来说，不会。好吧，那么宽大的尘卷风（尘暴）能套着龙卷风吗？不可能，理由很简单，因为龙卷风从天而降，但尘卷风则是拔地而起。这幅主题影像所呈现的是陆龙卷，这是一种不寻常型态的龙卷风，偶而会出现猛烈的雷暴系统之边缘。这例陆龙卷，则是由一位经验丰富的追风者，于2019年6月在美国堪萨斯州拍摄及辨认。最中心的是真正的龙卷风，而其外鞘可能是由中心龙卷风抛出的大量尘埃所聚成的。截自目前为止，唯一确定会产生龙卷风的行星是地球，不过太阳表面也有类似龙卷风的活动，此外，尘卷风在火星上很常见。 (landspout 陆龙卷)
