Supercell thunderstorm

The supercell thunderstorm is a special form of thunderstorm, which is characterized by its circling
Updraft (mesocyclone) is marked. A thunderstorm is defined as a supercell thunderstorm,
if at least one third of the updraft rotates, this rotation continuing as long as the convection
must stop (approx. 10 to 20 minutes). In addition, the updraft and downdraft areas must be separated
be so that the updraft area is not washed away by precipitation. In order for a rotation to take place
the wind shear must be vertical, which means that the wind direction and strength change with increasing
need to change height. Supercell thunderstorms are the most devastating thunderstorms, with about 20-30% of all
Supercells produce tornadoes as well as heavy hail. Supercell thunderstorms are the longest-lived
all forms of thunderstorms.

Classification of supercell thunderstorms based on precipitation intensity.

• LP supercell (low precipitation supercell):
  The LP supercell has a small precipitation field and is confined to the nucleus.
  Large hail can occur here, while tornadoes are rare.
• Classic supercell:
  The classic supercell is the most common type of supercell. The precipitation area
  is larger and there is more precipitation, with tornadoes occurring more frequently.
  They produce a hook echo on the radar screen.
• HP supercell (high precipitation supercell):
  The HP super cell is a cell with a high precipitation rate, which poses a great danger due to possible
  represents tornadoes because they are obscured by the heavy rainfall. These thunderstorms are for
  responsible for most deaths in the US. The precipitation area is very large, resulting in a
  fairly large field leads to heavy rain and hail. The heaviest precipitations in the cell nucleus often have
  a kidney-shaped structure.

With a few exceptions, the supercell thunderstorms only occurred in the USA. In the meantime, however,
proved that under suitable conditions they can occur in many regions of the world. It is
proven that almost all of the most dangerous tornadoes emerge from the supercells.
