A different spin on an Oklahoma twisterPosted Apr25, 2006 at 12:17 AMNearly all tornadoes in the Northern Hemisphere spin counterclockwise -- the same direction hurricanes, low-pressure systems, and even most small whirlwinds and dust devils spin. It's due to the Earth's rotation, called the Coriolis effect, a subject to be fully explained another day. A very small number of tornadoes, though, rotate clockwise ... like the one linked here on Oklahoma City's KFOR-TV, shown as it damages the El Reno, Oklahoma airport. |
