<sod>A '''thunderstorm''', also known as an '''electrical storm''', a '''lightning storm''', or a '''thundershower''', is a type of [[storm]] characterized by the presence of [[lightning]] and its [[acoustics|acoustic]] effect on the [[Earth's atmosphere]] known as [[thunder]].<ref>{{cite web | date = 21 April 2005 | url = http://www.weather.gov/glossary/index.php?letter=t | title = Weather Glossary – T | author = National Weather Service | publisher=[[National Oceanic and Atmospheric Administration]]| accessdate = 2006-08-23}}</ref> Thunderstorms occur in association with a type of [[cloud]] known as a [[cumulonimbus]]. They are usually accompanied by [[Wind|strong winds]], [[heavy rain (meteorology)|heavy rain]] and sometimes [[Thundersnow|snow]], [[Ice pellets|sleet]], [[hail]], or, in contrast, [[Dry thunderstorm|no precipitation]] at all.  Thunderstorms may [[thunderstorm training|line up in a series]] or [[rainband]], known as a [[squall line]]. Strong or severe thunderstorms may rotate, known as [[supercell]]s. While most thunderstorms move with the mean wind flow through the layer of the [[troposphere]] that they occupy, vertical [[wind shear]] causes a deviation in their course at a right angle to the wind shear direction.They are awesome. i like trains.<eod>
