What impact could the time period (e. g., day, month, year) chosen to determine the historical average have on our understanding of SSHD?

Abbreviated as mg-25.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way.
