Noam Hassenfeld和Brian Resnick：龙卷风来势汹汹，破坏力巨大，预警时间短且准确率低，这主要是因为气象学家难以预测哪些雷暴会产生龙卷风，以及龙卷风形成的具体机制。现有预警系统依赖于龙卷风的直接观测（发现即预警），导致误报率高，降低了公众的信任度。 Moe Oduwani：亲身经历了龙卷风袭击，预警时间只有7-10分钟，且预警的可靠性存疑。 Robin Tanamachi：龙卷风形成于超级单体雷暴，但其如何从大型旋转云团转化为触及地面的龙卷风，仍然是一个未解之谜。 Jeff Weber：龙卷风追逐对于收集数据至关重要，因为现有雷达技术无法捕捉龙卷风形成的快速过程，而要全面了解龙卷风，需要收集更多数据，包括龙卷风周围不同高度的大气数据。龙卷风本身的复杂性和多样性也增加了预测难度。但龙卷风的形成机制符合已知的物理定律，只是需要更精细的数据来解释其细节。

Tornadoes are unpredictable and deadly, with little warning time. A personal account from East Nashville highlights the limited time residents have to seek safety.

Shownotes Transcript

8 minutes, 24 seconds. That’s the average amount of warning time people get before a tornado touches down. To do better, and to understand tornadoes, scientists need to confront more of these storms, head on.
