What is a super storm cell?
A supercell is a highly organized thunderstorm with some components that set it apart from other “garden variety” thunderstorms. Supercells have the capability to produce tornadoes, damaging hail and strong downdrafts (which translate into straight-line winds at the surface).
What causes a supercell thunderstorm?
When environmental winds are favourable, the updraft and downdraft of a storm become organized and twist around and reinforce each other. The result is a long-lived supercell storm. These storms are the most intense type of thunderstorm.
What happens in a supercell thunderstorm?
On the thunderstorm spectrum, supercells are the least common type of thunderstorm, but they have a high propensity to produce severe weather, including damaging winds, very large hail, and sometimes weak to violent tornadoes. If the environment is favorable, supercell thunderstorms can last for several hours.
What is a cyclical supercell?
Cyclic Supercell: A thunderstorm that undergoes cycles of intensification and weakening (pulses) while maintaining its individuality. Cyclic supercells are capable of producing multiple tornadoes (i.e., a tornado family) and/or several bursts of severe weather.
What are the 4 types of thunderstorms?
The Four Types Of Thunderstorms
- The Single-Cell.
- The Multi-Cell.
- The Squall Line.
- The Supercell.
Is the #1 killer among thunderstorm hazards?
Every thunderstorm produces lightning, which kills more people each year than tornadoes. Heavy rain from thunderstorms can lead to flash flooding, which is the number one thunderstorm killer. Strong winds, hail, and tornadoes are also dangers associated with some thunderstorms.
How fast do storm cells move?
The speed of isolated storms is typically about 20 km (12 miles) per hour, but some storms move much faster. In extreme circumstances, a supercell storm may move 65 to 80 km (about 40 to 50 miles) per hour.
What does a supercell look like on radar?
Supercells often can be identified by viewing Doppler radar images. A classic supercell has several distinctive characteristics on radar including the hook echo, areas of enhanced reflectivity, and a bounded weak echo region. A low-level hook is often present on the right rear side of the storm.
What is the longest thunderstorm recorded?
