Tornado and Putting Beliung are just the same, the difference is only in the reference and the scale of it's intensity. In Indonesia known as Tornado Center angina or angina leysus , the difference is only in its intensity scale, in Indonesia only on the scale of tornado F0 and F1.
a) Definition of a tornado
According to the Dictionary of Meteorology (AMS 2000), a tornado is "a rotating column of air with the firm, arising from clouds or from cumuliform bottom cumuliform cloud, and often (not always) looks like a funnel cloud." In other words, a classified vorteks as a tornado, must be connected to the ground and cloud base. Meteorology experts have not found an easy way to classify and define tornadoes. For example, there is no clear distinction between mesosiklon (parent thunderstorm circulation) on the surface with a large weak tornado. It was known that the tornado funnel is not visible. Also, at what speed to the surface of a tornado cloud begins.
b) How a tornado is formed
Most tornadoes are destructive and deadly because of supersel, namely a rotating thunderstorms with a regular circulation called mesosiklon. Supersel also can cause damaging hail, strong winds non-tornadoes, lightning, and sudden floods. Tornado formation can generally be seen on the things that happen on the scale of the storm, in and around mesosiklon. Growth of tornadoes associated with temperature differences in air mass at the edge down (downdraft) around mesosiklon (occlusion downdraft). Mathematical modeling study of the growth also indicates a tornado tornadoes can happen without such temperature patterns; even the fact, the observed temperature variation is very small in several tornadoes that caused great damage in the history of the May 3, 1999.
c) The directions a tornado coming
• Can be anytime happen each year
• Can occur anywhere in the world, but in the high-latitude regions are usually happen in summer or spring.
• The American tornadoes can occur at 15 to 21 LT
• In Indonesia happen around Sumatra and Java
