Waterspouts are, I believe, more frequently seen at sea than on land,
but I have an account from my brother, Mr. F.E. Savory, of one he saw
many years ago in Wiltshire. He writes:
"When I was at Manningford Bruce in 1873 or 1874, I saw a dense black
cloud travelling towards the southeast, the lower part of which became
pointed like a funnel in shape, waving about as it descended until, I
suppose, the attraction of the earth overcame the cohesion of the
cloud's vapour, and it discharged itself. I could see it looking
lighter and lighter, from the middle outwards, until it was entirely
dispersed. I heard that the water fell on the side of the Down near
Collingbourne, about five miles off, and washed some of the soil away,
but I did not see that. The weather was stormy, but I do not remember
the time of year or any other particulars."
It would seem that a waterspout is caused by a whirlwind entering a
cloud and gathering vapour together by its rotary action into such a
heavy mass that it descends in the funnel shape described. We are all
familiar with the small whirlwinds that travel across a road in
summer, carrying the dust round and round with them; these are called
"whirly-curlies" in Worcestershire, and are regarded as a sign of fine
weather. I have sometimes seen quite a strong one crossing rows of hay
just ready to carry, cutting a clean track through each row, and
leaving the ground bare where it passed.
