I like the way lightning - after it strikes - seems to have a lingering dissipating energy. Don't know how to describe it but you can watch the lightning disintegrate.

I am going to assume that what is seen after the lightning is the cooling down of the atmospheric molecules, N2, NO, NO2, O2, CO2, CO, HC, and H2O and all other combustion elements.

What is also common is a reverse flow as current reverses direction. This is not seen in this video.

Oak Ridge National Laboratory has decommissioned its Alpine storage system, a 250-petabyte storage system that held data for the Summit supercomputer and its other support systems. The Summit supercomputer, currently the world's ninth-fastest supercomputer, will be retired on November 1st, but its aging Alpine storage didn't survive that long.

As ORNL prepares for the Discovery system—a computer set to be the world's fastest with an estimated 8.5 exaFLOPS of performance—the time has come to decommission its predecessor, Summit. Summit was initially set to be shut down in 2023, but its high productivity rates led the Department of Energy to keep it in operation for another year. Unfortunately, its storage could not last so long.


Alpine was part of ORNL's storage solution for Summit and its peripheral systems, holding scratch data from the supercomputer and its external nodes, which pre- and post-process Summit's calculations. The Alpine storage system held 250 petabytes of capacity inside 32,494 10TB NL-SAS drives. Made up of 77 IBM Elastic Storage Server (ESS) nodes, the system could have 2.2 TB/s random read and write speeds at its peak. Still, in recent years, drive failure rates have hit unacceptable levels, necessitating installing a stopgap replacement storage system, Alpine2.
