Reading, Berkshire UK
Polar/Arctic Maritime Airmass heated with long land track
Duration: 30 minutes
Type: Linear Multicells
Average lightning type: C-G
Average discharge rate: Cell 1: 136s, Cell 2: 97s
Footage Quality: VHS / Hi-8
Location is Reading
now (first summer at Uni).
Produced from a cool and unstable polar/arctic maritime flow post-system.
These cells (2 in this instance) were reaching maturity as they took in the
inland surface heating across the Midlands. However this particular cluster
was weakly electrified and hard to film from my hall, however the cloud
shots were good and the second cell produced some C-G and possibly a
positive flash (P-F) which produced a long booming thunder.
Cell 1 and Cell 2 were the first two of an array of cells to cross Reading
on this day. There was a short lull between the two cells which I didnít
feel was long enough to class them as two separate storms. They were
probably sharing the same anvil. However, behind these two cells a
strong convergence zone was setting up and approaching, which shortly after produced
T0045, an incredibly active squall-line
that left these two cells shouting without a microphone.
