Rare Fire Tornado in BrazilA rare fire whirl, also known as a fire tornado, briefly made an appearance near Sao Paolo, Brazil. The swirling fire tornado was reportedly several meters high and brought traffic to a standstill. The Christian Science Monitor explains how the fire whirl formed.
Severe drought and strong winds in Sao Paolo have created conditions which makes fire whirls possible. It has not rained for three months in Sao Paolo. Take a look:When there is a warm updraft of air and convergence of fire, say from a wildfire, a vortex of flame can occur. As the heated air from the fire rises, strong air currents cause flame to spin, shaping it into a tornado.
