No. 62: Mar-Apr 1989
Of late, the cereal fields of Britain have been visited by a phenomenon which flattens the crops in nicely geometric circles, rings, and even patterns of circles. The meteorologists attribute these circles to unseen vortices in the atmos phere; more radical speculators invoke UFOs and mysterious Russian weapons.
Pertinent to the explanation of this phenomenon are recent sightings of vapor vortices in regions where crop circles are common. While no one has yet seen these vortices gouging out circles, these visual manifestations betoken strong circular winds in the proper locations. Here follows a recent account: "Looking across the field of winter wheat to the east..., he suddenly noticed at a distance of 80 metres... what he took to be a large puff of white 'bonfire smoke' rising to 15 feet (5m) maximum height. The outer part of this 'smoke' column was scarcely rotating but the middle part, which was too thick to see through, was spinning rapidly. In a couple of seconds the effect had ended; the spinning central column had gone and the residual 'smoke' or cloud of fog drifted gently in the prevailing light north-east wind towards the southwest and dissolved after going several yards. He used the word smoke out of convenience but said that the effect was more likely caused by water vapour, cloud droplets or fog. He further emphasized the swiftness of the appearance and disappearance of the phenomenon. It had arrived suddenly like 'smoke from a distant cannon' or just as if 'a smoke-filled or fog-filled balloon had suddenly burst.' That is to say, it emerged as if from nowhere. He made the further point that the spinning column might have been very much longer than he could judge, for he realized that the only part he could see was the part rendered visible by the smoke or fog. The diameter of the cloud was about the same as its height, viz 4 or 5 metres."
The same phenomenon appeared again a few seconds later, and still again 5 minutes later. Many crop circles have been found in the fields around Yatesbury.

Comment. There may be a connection between these visible vortices and the curious wind gust reported SF#61. Even more speculatively, there might be a connection to the strange cloud plumes seen in recent years over the Soviet Union.
