From The Star 18 Aug 2010:
Teach public how to deal with tornadoes
Vong Chin Siang’s recent picture of a tiny tornado in The Star’s “Thumbnails” is one more proof that mini-tornadoes exist in the country.
Mini-tornadoes were behind some of the reported freak storms that blew off roofs and toppled trees around the northern part of the country recently.
This phenomenon has been reported in several neighbouring countries but its existence has not been acknowledged by the local authorities.
They are created by rotating wind systems in the thunderclouds and become mini-tornadoes when the bottom end of the spinning wind column touches the ground.
Fortunately, their lifetime is short, lasting from several seconds to several minutes. However, they can cause destruction to the buildings and trees that come in contact with them.
Vong’s picture of the tiny tornado clearly showed the flying debris that can be very dangerous to people caught outdoors.
The final approach of a mini-tornado is usually accompanied by a loud roaring sound like that of a big truck or train.
Therefore, anyone who witnesses sudden strong winds and then hears a loud roaring sound should immediate seek shelter under a table or bed to avoid being struck by debris from damaged roofs or broken trees.
Several mini-tornado events occur around the country every year and with global warming, this phenomenon is expected to increase in the future. It is more common but less dramatic than the tsunami.
Perhaps the authorities should acknowledge its existence and come up with a simple safety procedure that can be posted on notice boards in schools and public buildings around the country.
Well then, since rising global temperatures will cause more tornados, we can look forward to fewer tornados. Because there has been no statistically significant warming in the past 15 years, despite continually rising carbon dioxide levels.
Besides, doesn’t he know that apparently Global Warming Reduces Tornadoes and Hurricanes?
