Terrible tornado Tornadoes,we may have all heard,but everyone to the tornado familiar?Let me introduce!Tornadoes are vortex:air around the shaft spinning coil dragon,the dragon roll centre pneumatic extreme decrease attraction,near the ground dozen meters thick a thin layer of air inside,air is from all directions inhaled vortex bottoms.And immediately he turned around the axis of eddy current,the dragon roll up the wind always cyclones sex,the center of the air pressure can than surrounding low air pressure to 10 percent.Tornadoes power is strong,harmfulness is very big also.In 1995 in American Oklahoma adeimantus Moore city in a land tornadoes,heavy objects such as roof blown out of ten miles away.Most debris falls on land tornado channel of the left side,by weight ranged often have a well-defined landing zone.The lighter fragments could fly to more than 300 kilometers outside before landing.Dragon volumes of attack suddenly and violently,produce the wind is the strongest in the ground.In the United States,a tornado annually cause deaths after the thunder.It for building destruction is quite serious,often be devastating.In intense tornadoes,house roof as gliding like flying.Once the roof coiled left,other parts of the house will follow destruction.Therefore,building houses,if can strengthen the roof of the firm sex,will help to prevent tornadoes caused heavy loss during transit.When we encounter a tornado coming,we should take the following methods from a tornado attack:first,when a tornado coming,if we at home,you should immediately ran downstairs stair avoid tornados.Second,the United States is a tornado in most places,most foreign - 8pm,the time in had better not to travel to the USA.Three,tornado coming in driving bicycle should immediately discard all items,such as low into the subway of place.Fourth,in the wilderness meet tornado should find solid rock,and couldn't find words,should avoid a tornado in bridge.On the hillside should find a quick relatively big rocks from a tornado.Tornadoes which side,you should avoid in rock in the opposite direction,When a tornado after a rock,should immediately swap places,in the opposite direction to avoid it.Well,now you should have further understanding of tornado!When you're really in a tornado,they should take the above method to escape!tornadoes A tornado was a mystery for a long time,it is precisely because of this reason,so it is necessary to understand it.Tornadoes suddenly and violently,produce the wind is the ground the strongest.Because of its occurrence and

Terrible tornado Tornadoes, we may have all heard, but everyone to the tornado familiar? Let me introduce! Tornadoes are vortex: air around the shaft spinning coil dragon, the dragon roll centre pneumatic extreme decrease attraction, near the ground dozen meters thick a thin layer of air inside, air is from all directions inhaled vortex bottoms.
