I was reading this paper, and stopped at the mention of the 1955 observer's report of a smell of burnt sulphur in the vicinity of the tornado.
I have been struck by contemporaneous accounts of the Black Death, cited by Dr Mike Baillie in support of his cometary theory of its origins. The review of his book by Laura Knight-Jadczyk here
http://www.sott.net/articles/show/14568 ... Connection contains some of them. For example:
As it happens, in the 1340s there was a veritable rash of earthquakes. In Rosemary Horrox's book, The Black Death, quoted by Baillie, we find that a contemporary writer in Padua reported that not only was there a great earthquake on 25 January 1348, but it was at the twenty-third hour.
In the thirty-first year of Emperoro Lewis, around the feast of the Conversion of St. Paul (25 January) there was an earthquake throughout Carinthia and Carniola which was so severe that everyone feared for their lives. There were repeated shocks, and on one night the earth shook 20 times. Sixteen cities were destroyed and their inhabitants killed.... Thirty-six mountain fortresses and their in habitants were destroyed and it was calculated that more than 40,000 men were swallowed up or overwhelmed.
(The author goes on to say that he received information from "a letter of the house of Friesach to the provincial prior of Germany):
It says in the same letter that in this year [1348] fire falling from heaven consumed the land of the Turks for 16 days; that for a few days it rained toads and snakes, by which many men were killed: that a pestilence has gathered strength in many parts of the world. (Horrox)
From Samuel Cohn's book:
... a dragon at Jerusalem like that of Saint George that devoured all that crossed its path .... A city of 40,000 ... totally demolished by the fall from heaven of a great quantity of worms, big as a fist with eight legs, which killed all by their stench and poisonous vapours. (Cohn)
Adopting a rational standpoint vis-a-vis these descriptions must include consideration that the boundary between literal/figurative language cannot have been the same then as it for us today - the type of considerations pertinent to an EU interpretation of the polar Tree of Life myths. The "rain of toads and snakes" I have privately conjectured to refer directly to plasmoids.
The occurrence of sulphur in both subjective and objective accounts of electrical and/or plasma action I understand as related to the conversion of oxygen to sulphur, both being in the same group in the periodic table. The question I have asked myself over the Black Death flowing from the conjecture, is how a medieval population could succumb to a localized occurrence of (presumably) SO2 of atmospheric origin - would people not instinctively run away? Would it not be rapidly dispersed? And, specifically, if the cause was directly the plasmoids, would they not have succeeded in saving themselves? Yet they didn't, and indeed, suffered effects that were contagious to others, fatally so.
What caused me to stop was to check the periodic table relation between nitrogen and phosphorus. The latter has some foul smelling compounds, such as phosphine (PH3), primitively weaponized in WW1. And phosphorus itself has been weaponized, and used recently in several places in the Middle East on people - once in contact with human tissue, it cannot be removed by water or other safe solvents, but continues to burn until chemically exhausted. The range of organic compounds formed by phosphorus with other common elements is generally highly toxic. Presumably direct contact by other people with the affected areas could transfer the active agent - with enough contacts, it could give rise to the appearance of a contagious epidemic.
I found I had remembered correctly: phosphorus stands to nitrogen, as does sulphur to oxygen. Phosphine is a structural analogue of ammonia (NH3).
Electrical modification of the atmosphere can be expected (a priori at least) to act on both its oxygen and nitrogen components.
So it is intriguing to read (select P in the periodic table at
http://www.dayah.com/periodic/):
It was known from early times that the glow [of phosphorus] would persist for a time in a stoppered jar but then cease. Robert Boyle in the 1680s ascribed it to "debilitation" of the air; in fact, it is oxygen being consumed. By the 18th century, it was known that in pure oxygen, phosphorus does not glow at all;[4] there is only a range of partial pressure at which it does. Heat can be applied to drive the reaction at higher pressures.[5]
In 1974, the glow was explained by R. J. van Zee and A. U. Khan.[6] A reaction with oxygen takes place at the surface of the solid (or liquid) phosphorus, forming the short-lived molecules HPO and P2O2 that both emit visible light. The reaction is slow and only very little of the intermediates is required to produce the luminescence, hence the extended time the glow continues in a stoppered jar.
Could this be the mechanism causing some of incandescent effects observed in the tornado funnel of that 1955 report (and similar reports not attributable directly to short-lived lightning)? I think experimental investigation into the possible presence of phosphurus in tornados could answer that.
