A water sprout is identical to the land-formed tornados but this
sign can only happen at the sea... Harmless to land but sometimes
can create a high underwater reverse current due to the centrifugal
spiralling effect... Speed of the centrifugal force can be as high
as 150 km/h, thus can caused reasonable damages to ships if in
direct path...
Forming of water sprout mainly is due to the low pressure of
moisture at sea level and meeting of high pressure of rain clouds,
thus causing a static pull, forming a vertical column of
vacumn...
