1 The CT scan is a medical imaging procedure that uses x-rays and digital computer technology to create detailed pictures of the body.  It can image every type of body structure at once, including bone, blood vessels and soft tissue.
A waterspout is a whirling column of air and water mist. According to NOAA's National Weather Service, the best way to avoid a waterspout is to move at a 90-degree angle to its apparent movement. Never move closer to investigate a waterspout.Some can be just as dangerous as tornadoes.Waterspouts fall into two categories: fair weather waterspouts and tornadic waterspouts. Tornadic waterspouts are tornadoes that form over water, or move from land to water. They have the same characteristics as a land tornado.hile tornadic waterspouts develop downward in a thunderstorm, a fair weather waterspout develops on the surface of the water and works its way upward. By the time the funnel is visible, a fair weather waterspout is near maturity. Fair weather waterspouts form in light wind conditions so they normally move very little.
This exceptional spout is an example of one that apparently was spawned by thunderstorm-squall conditions similar to those that produce tornadoes over land. There is much confusion in classifying waterspouts. For many years, they were called tornadoes over water, a definition still in wide use.
