Laser Beams Used to Create Filament Paths Could Potentially Direct Lightning

Lasers beams have been used for the first time to trigger and divert lightning bolts. It was first postulated in the 1990s that lasers could be used to create a low-resistance pathway through the atmosphere, allowing lightning bolts to use the path of least resistance.

Friction on Raindrops Dissipates Almost as Much Atmospheric Energy as Turbulence

A new study published in the journal Science states that rainfall soothes the atmosphere, almost as much as turbulence. They calculated that a substantial portion of the energy that drives wind and air circulation in the Earth’s atmosphere is dissipated as friction by raindrops falling through the air.
