[b-hebrew] Thera quote

Hallo Dora Smith,

you have misunderstood me. In my reconstruction was the exodus at the same time of the year as reconstructed by the repartition of the Theran ashes following the prevailing winds in September over the Mediteranean. Due to many details in the Exodus story one has to redate this event to July-September too.

My point is that the winds can influence only the repartition of such volcanic material which was ejected in the lower athmospheric strata. Such powerfull outbursts sent into the stratosphere, producing also climatic changes as observed in the tree-rings, are not under the influence of these wind, which are a topic regarding only the lower atmospheric regions.

It is nothing exceptional to expect from the Theran eruption such a mixed behaviour, that not all eruptive material is sent high. As said, this is a matter of ballistics, of how powerfull and under which angle such a shot is sent.

Best regards,
Bányai Michael
