| Title: | Natural Hazards- Tornado Trouble |
| Issue Date: | Apr-2010 |
| Publisher: | CSIR |
| Abstract: | The word Tornado comes from
the Spanish word, tronada,
meaning thunderstorm.
Thunderstorms are usually
classified into three types: singlecell,
multi-cell, and super-cell.
Super-cells can produce hail,
reach damaging wind speeds,
cause flooding, dangerous cloudto-
ground lightning, and of
course, heavy rain. Usually about
a third of super-cell
thunderstorms go on to produce
tornadoes. For this to happen,
first a meso-cyclone or a tornadoprecursor
has to form. A mesocyclone
is a deep, continuously
rotating updraft. Once a mesocyclone
forms in a super-cell,
there’s a roughly 50% chance
that it will escalate into a tornado
in around half an hour. |
