|SEVERE STORM STRUCTURE:|
METEOROLOGIST JEFF HABY
The updraft region in
supercells will often lack precipitation. This is most true for developing
supercells and for classic/LP supercells. As a supercell matures or has a
high moisture content, often precipitation
will wrap around
the updraft region and eventually fall into the updraft region. The updraft region of a supercell will be
tilted with height. This will deposit the
precipitation away from the updraft and thus this also results in less precipitation in the updraft region. Being in
the rain free base region offers an awe-striking view of the storm.
The diagram below shows the rain-free base at "G".
