My question is about the effects when driving through tunnels. Many of our expressways (motorways, freeways) are built in tunnels beneath the mountain ranges or under the ocean. When driving under the New Territories mountain ranges during active thunderstorms, I can hear every lightning discharge going off and presumably stopping when it hits the ground a kilometre above my head. But when driving under Victoria Harbour to Hong Kong Island, I can hear the static going off every few seconds as I go down into the tunnel, but once under the water, I get crystal clear radio reception without the slightest sign of lightning static. As I drive up the ramp onto the island, I find the storm is still going as strong as ever and can again hear every lightning stroke on the radio as it goes off. Can anyone put forward any suggestions as to why I can hear the static through a kilometre of rock but not through a hundred metres of sea-water?

It occurs when there is a rapid change of Px from high to low. The amount of water coalescence that is visible is dependent on the relative humidity and the degree of Px change. When there is low humidity you need a more rapid and greater change of Px to get the same type of effect as when the humidity is high and the changes are not as great. A couple of examples that you can observe this is 1/ When an aircraft is on finals and there is a high ambient humidity and because the aircraft is at a high angle of attack, you will see the top of the wings disappear in a cloud of water vapour. If you happen to be looking down on this you can sometimes notice that some areas on the wing have vapour and some don't. This is because the amount of lift created over the wing is not equal on all parts. So you get some areas of water coalescence and some without. 2/ If you happen to go into a Defence Force Recruiting office they may have a photo of a F111 in a left hand bank with its leading edge flaps/slats deployed. Right at the join of this to the wing root you will see a small amount of water coalescence here but not over the whole wing. 3/ My favorite. Open a bottle of beer (or any carbonated product pref. in a clear bottle) rapidly and you will get water coalescence. If you did this slowly enough you wouldn't get any. There are lots of other examples but these are probably the easiest to see. If you need any more info feel free to ask and I'll dig out my books if I can't answer them off the top of my head.

Radio broadcasts are repeated through tunnels so emergency broadcasts can override these. Possibly the lightning strikes are having an effect on the radio repeater circuitry rather than on your radio itself, and when under the water, the water is maybe disipating the electrical charge a lot smoother. I'm not an expert and this may or may not be correct, but tis an idea from me. cyas, Andrew > To resurrect a month-old thread with a new related question: > Every time we have a thunderstorm here, I pick up the lightning discharges > on the AM car radio usually before they announce the hoisting of the > Thunderstorm Warning. > My question is about the effects when driving through tunnels. > Many of our expressways (motorways, freeways) are built in tunnels beneath > the mountain ranges or under the ocean. > When driving under the New Territories mountain ranges during active > thunderstorms, I can hear every lightning discharge going off and presumably > stopping when it hits the ground a kilometre above my head.

First, the tunnel under the mountains. The rock is not a highly effecient conducter, although it is likely that there are pockets and/or seams of minerals in it that are. It therefore may be considered as as being made up of a rather random arrangement of capacitors, albeit rather leaky ones as the surrounding rock is partially conductive. When lightning discharges in the atmosphere, it induces electromagnetic pulses into the ground, so is able to easily induce strong charges through the randomly arranged mineral capacitors, which can then be picked up by the AM radio a kilometer below the surface. Now the tunnel under the sea. The sea water is a highly conductive medium, so may be very effective at absorbing the electromagnetic pulses generated by the lightning. The charges induced in the salt water are likely to be more or less evenly distributed over a very large area, so acting as a giant conductive sink for the charge and greatly diminishing the charge at any particular location in the water compared to that in the air above it. There would be little left of the electromagnetic pulse to be transmitted into the far less conductive rock below. Why it does not also effectively absorb the modulated electromagnetic waves of the AM radio signal is more of a mystery to me, however the ground wave from the transmitter antenna may provide an answer to this if it is not located a great distance from the tunnel.

Well I had a shower chase today! Early - Mid morning TCU / Cu Congestus forming on a very weak gulf line caused some excitement , but after a few odd 20mm or so showers the line passed out to sea and died. Better then nothing I say! Question:- Why is it so dry down South when La Nina conditions are presisting? As far as I remember La Nina is suppose to assist rainfall totals rather then induce drought conditions. My Mum at Taree say there are almost on water restrictions due to the major lack of any rain / decent activity since early in the Year! What in the hell is happenin? My Nan who lives at Port Kembla asked me to send her down a video of rain as it has been so long since they have seen major rain in the Illawarra (Michael T??). Season is well on the way here with arvo TCU + showers now present most afternoons inland and around the Roper River area. But with a very active monsoon in the North I think that it will be a while till we see any real organised activity - Maybe mid Oct. Paul in Darwin. PS - when is the next Sydney, WA & SA ASWA meetings? Chance that I may be able to make some of them if they are Mid-weekers and in the next few weeks. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ From: "Michael Thompson" To: Subject: Re: aus-wx: Shower chase!! & Question Date: Sun, 24 Sep 2000 19:59:01 +1000 Organization: X-Mailer: Microsoft Outlook Express 5.00.2014.211 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com We have had about 5mm in the last 6 weeks.

No I am not that excited by the weather in Adelaide at the moment but a thunderstorm would certainly change that!

I was reading a thread in another newsgroup and a person said he was driving through the Sydney Harbour tunnel, listening to a 'normal radio station' when an announcement of a lane closure was broadcast over the music. The emergency services also have repeaters installed in the tunnels so they can maintain communications with their control rooms. The smaller tunnels etc in Hong Kong obviously are not equipped with these repeaters but the larger or deeper tunnels must be equipped with either repeaters or feeds direct from the radio stations.

My suspicion is this has more to do with how the signals are fed into the tunnels than any direct reception of static. Radio waves tend not to penetrate rock or sea water very well. However, I'm more familiar with frequencies in the 30 - 1300 MHz range, perhaps 1 MHz will penetrate a little into rock. Seawater is a very good conductor, so it will tend to block radio waves. Someone more familiar with MW propagation may be able to tell more. Tony, VK3JED ..

My hapenny's worth: VLF (30 kHz and below) is quite capable of penetrating the earth and sea, cavers use it as do American submarines. Most lightning sferics are in the VLF region and produce various bizzare phenomenon.

I did notice down here that the rain (ha ha, but there was some) fell only where you would call the vegetation wet sclerophyl. Anywhere that it was dry sclerophyl no rain seemed to fall. Did it look like this around Mt.Kembla/Keira Michael? Perhaps the weather has got the s..ts with our explanations of its vagaries and is sticking to its guns. Will wave on my way to Sydney airport tomorrow (and on the way back 2 hours later). Waiting for Shaun Nowra P:S Sclerophyl, is this the correct way to spell it? Been way too many years since high school. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
