Tornado in Oklahoma City, 5 people killed
Massive tornadoes strike the Oklahoma City again on Monday, May 10 2010. At least five people were killed in the incidents. Two people were killed in Oklahoma City and three more people died in Tecumseh, about 45 miles southeast of Oklahoma City, said Jerry Lojka, acting spokesman speak for the Department of Emergency Management in the state.
Although the tornado had been observed on every continent except Antarctica, tornadoes are more common in the US. Tornado also commonly occurs in southern Canada, south-central and east Asia, east-central Latin America, South Africa, northwest and central Europe, Italy, western and southern Australia, and New Zealand.
Most of the tornadoes have wind speeds of 177 km/h or more with an average reach of 75 m and travel a few miles before dissipating. Some tornado wind speeds reaching more than 300-480 km / hr has a width of more than one mile (1.6 km) and can survive on surfaces with more than 100 km.
Tornadoes are defined by the Glossary of Meteorology as “a rotating column of air that integrates tightly with the soil surface and emerge from the bottom of clouds or clouds cumuliform cumuliform and often (but not always) visible as a large cloud. Half of the destructive and deadly tornadoes caused by supersel, namely the rotating thunderstorms with a regular circulation called mesosiklon. Supersel also can cause damaging hail, non-tornado winds, flash, and a sudden flood.
Tornado formation can generally be seen on the things that happen on the scale of the storm, both in and around mesosiclon. Growth of tornadoes associated with temperature differences in air mass at the edge down (downdraft) situated in the vicinity mesosiclon (occlusion downdraft). Study of a mathematical model of growth also indicates a tornado tornadoes can happen without such temperature patterns; even in reality, the observed temperature variation is very small in several tornadoes that caused great damage.
