Is Every Tornado Visible?
In short: Wind is invisible, so a tornado can touch the ground without a visible funnel; spotters, dual-polarization radar and one reporting study show how tornadoes are confirmed and how many may go unrecorded.
A 1:26 short film in the series “Invisible Atmosphere”, narrated by intellect_voice_01.
