Types of thunderstorms – the supercell


Supercells are the most powerful of all storms and have updrafts that rotate
Supercells produce the most intense tornadoes, largest hailstones, extremely heavy rainfall and strongest straight line winds

 Strong enough rotation throughout a supercell upraft can lead to tornadoes.

Types of thunderstorms – the squall line


Squall line
One or more storm cells will develop into a LINE complex
Strong straight line winds, heavy rain, hail and weak tornadoes can occur
Features include spectacular shelf clouds

Types of thunderstorms – the multicell




Two or more storm cells will develop into a complex.
These last much longer as a complex of cells than a single cell storm.

These can produce large hail, severe winds, heavy rain and even tornadoes.
