Electrometer
I'm now retired and back !!!
Monitoring of the Earths electric field does actually give warnings of impending storms. The normal field of several hundred volts positive, starts to dip as the charge in the atmosphere is disturbed. This can even be somewhat cyclic and is a precursor to a storm. Note that some storms have absolutely no electrical activity in them and the chart remains staunchly positive, even whilst its raining.
Then again, I have seen the buildup to a bad storm some days beforehand, as the atmosphere just keeps changing. Its visible to the chart long before an observer or weather radar.
Now, imagine if you will, a map, with places of equal electrical potential joined, not barometric pressure as we are used to. One would see storms build up, decay and so on, and long before any effects were observable or on radar.
Other things are also detectable, meteor showers as they ionize the atmosphere and disturb the field, and earth quakes, as the rock 'let go' and the piezo effect causes a electrical discharge.
Now the big one, nuke tests.
I have recordings of the nuke tests in the pacific by the French, and a nuke emits a electromagnetic pulse which is easily detectable many 1,000's km away.
I now use a computer data logger so have traces I may be able to post of storms and the positive and negative lightning discharges. Obviously, one detector cant give a range or bearing, but a network could, and even predict where the next lightning strike is gunna happen. An interesting development.
Anyway, better go now, Hi Alex.
