mesocyclone

• In a paper published this week in the journal Nature, the scientists show that the spontaneous formation of a "volcanic mesocyclone" -- a rotating, column-shaped vortex -- causes the volcanic plume to rotate on its axis. —  NSF News
• Washington, D.C. - infoZine - In a paper published this week in the journal Nature, the scientists show that the spontaneous formation of a "volcanic mesocyclone" -- a rotating, column-shaped vortex -- causes the volcanic plume to rotate on its axis. —  Kansas City infoZine Headlines
• The same process that creates a mesocyclone in a tornadic thunderstorm also creates a volcanic mesocyclone in a strong volcanic plume, Chakraborty said. —  Kansas City infoZine Headlines
• A volcanic mesocyclone sets the entire plume rotating on its axis. —  Kansas City infoZine Headlines
• The mesocyclone spawns waterspouts or dust devils, and groups the electric charges in the plume to form a sheath of lightning, as was so prominently displayed in the eruption of Mount Chaiten. —  Kansas City infoZine Headlines
