Understanding Tornado Development and Prediction in Supercells
Tornados, including Supercell Tornados, are powerful rotating weather phenomena that can be predicted through various methods such as radar imagery and storm features. This article explores the development of tornados, focusing on how Supercell Tornados form from mesocyclones within supercell thunderstorms. It also delves into prediction techniques used by the National Weather Service and the importance of early warning systems in tornado-prone areas.

Warning Systems Weather Service Warnings: Severe Thunderstorm Warning Tornado Watch / Warning Local Siren Systems Only Present in areas heavily affected by tornados
Summary Tornados are: Strong, Violent, rotating updrafts There are two types of tornados Supercell and Non-Supercell Supercell Tornados develop from the internal mesocyclone of a supercell thunderstorm Supercell thunderstorms can be predicted by storm features from the ground and through radar imagery The National Weather Service uses these predication methods to determine the need for watched and warnings.
Conclusion You should now be able to: Describe a Tornado Discuss how Supercell Tornados Develop Examine how Tornados can be Predicted Apply Prediction Methods to Early Warning Systems
