    I think people are also under estimating it. Or maybe you're a bit upset you are too far south?

    I think the majority of the country who aren't really in the path of it are making too much of it. The East may very well see some decent stuff, but I think there's a hell of a lot of clutching of straws from everyone else.

    I'm not upset as I wasn't expecting anything in the first place.

    Found my thunderstorm diaries that I used to keep (well 3 of them anyway).

    By this time in '97 we had already had 5 thunderstorms, 2 of which were all nighters. According to the diary, I classed a thunderstorm as being over 30 minutes long, anything shorter was classed as 'a day with thunder' of which we had had 23.

    Compare that to 2011, where we have had 2 thunder days and only one of those days could be considered a thunderstorm.

    I'm sorry i just don't buy it when people say we are having the same amount of storms as ever.

    On a separate note, it is almost quite smoggy today.

    I think it would depend on the quality of the conductor on the Tower...if the conductor is of very high conductance, the lightning should travel to earth via this. Remember that electricity will always take the route to earth offering less resistance.

    When we touch things which have become electrified, if we're shocked it is because the object isn't sufficiently earthed. For example, sometimes when you get out of a car you get an almighty shock, resulting from a build up of static electricity. The car isn't sufficiently earthed as the only part of the car in contact with the ground are whopping great rubber tyres - the electrical potential cannot travel through these to get to the ground so remains on the car's shell. When we get out of the car and touch the door with our hand, the moment we touch the ground with our feet we are earthed and offer the charge a means of escape. It is then we feel the shock.

    In the case of the Eiffel Tower, the lightning conductor has no great rubber tyres preventing sufficient earthing. Therefore, the electricity will zip to ground having no inclination to go through us. IF, however, the lightning conductor is broken (cables snapped/corroded) such that our bodies offer less resistance, then I think a shock would be possible.

    Thanks for simplifying things for me. My physics is not my strongest subject.

    I guess I just figured that on the way down to the floor that lightening might pass through you if you were touching something metal.
