Re: OT Why Lightning Strikes Twice as Often Over Shipping Lanes
I'm with David on this one and my PhD was on thunderstorm electrification. 60 years ago it was commonly known that the most common nucleating agent for cloud droplets was sodium chloride from sea spray and thunderstorms existed long before man started to build marine engines. Since cloud to ground (or cloud to sea) lightning strikes are initiated by a leader of plasma moving upwards, a charged plume of gas and particles from a funnel might ease the formation of the electrical discharge but this would only happen very close to where the lightning discharge would have occurred anyway; the lightning conductor on the building next door will not protect your building.
RUBBISH! most shipping lanes are close to land and the clouds generally require the heat from sun on land to build! so there will be more storms close to land, the area Sardinia- Rome -Genoa is a mass of storms virtually every night in summer!
having cruised the area several times it is interesting that a nice tall metallic structure the ship on a flat sea has NEVER been hit whilst i have seen hundreds of lightning strikes down to the sea??
