The past 2 weeks have been really interesting around the
During February 2010 the Underberg saw the development of a very large and well defined funnel cloud over the Sangwana Mountain. It occurred during the afternoon hours and it is believed that the funnel cloud never reached the ground, which means it can not be classified as a tornado, though is equally impressive.
The funnel occurred after temperatures rose to 33’C where convective thunderstorm development began in a high CAPE and high shear environment. The instability in the air combined with the right wind profiles allows for a storm to turn super-cellular and can then drop a tornado if conditions are ideal.
There is no way to predict which supercells drop tornadoes and which don’t.
