9/22 - NOSL investigations BERNARD VONNEGUT - SUNY (Albany) MARX BROOKS - NM TECH 1. lightning lecture + [[delta]] V ~ 250KV between Earth & "[[infinity sign]]" [[image]] the charge separation between Earth & atmosphere is maintained by dust storms, water falls, volcanoes, etc...). Charge separation during TRW is primarily generated by TRW processes themselves. Types of lightning: intracloud (~10x more frequent than cl-gnd) cloud to ground cloud to air outside inside a cloud, charge separation appears to be [[circle with + sign in it]] near top, [[circle with - in it]] near bottom: [[see diagram]] PROCESS: 1. step - leader phase: "bolt" move out in ~50m "steps" from cloud.... it breaks down (arcs across) ~ 50m of air, establishes a conductive path along that 50m... that line then acquires potential ([[φ Phi symbol]]) of cloud, ->
