What can create a horizontal spinning column near Earth's surface eventually turning into a vertical tornado?

The horizontal rotation is caused by wind shear, differences in wind speed and direction with altitude. This can create horizontal vorticity in the air. This horizontal rotation then gets caught in the updrafts of thunderstorms in the area, which turn this rolling into vertical rotating columns within the storms. Eventually, the rotation in the storm can tighten and intensify to produce a tornado.

True or false Motion parallel to earths surface is vertical motion Motion parallel to earths surface is vertical motion?
False. Consider a car moving on the road, along the earth's surface. That is considered to be Vx or Horizontal motion or velocity. If the car were to move perpendicular to the earth's surface that would be Vy or Vertical motion and velocity.
What is the steps that change wind shear into a tornado?
When wind shear occurs, air moves at different speeds, heights, and directions. This can eventually lead to the formation of a mesocyclone. A mesocyclone is a rotation column of air, starting at horizontal, but becoming vertical when a powerful updraft knocks it vertical. If a RFD is present, it will rotate downward hugging the surface of the mesocyclone, funneling a smaller and smaller point as it reaches the bottom. This is like a skater pulling in her arms, leading to faster rotation. The same is true for tornadoes. If a powerful updraft creates a low pressure area near the surface, the combination of RFD pushing downward and low pressure area near the surface, drawing the funnel downward, could eventually lead to a complete tornado.
Velocity parallel to earths surface?
gravity
Horizontal movement of air in relation to earths surface?
Answer:Wind
Horizontal movement of air in relation to the earth's surface?
Answer:Wind
Why a vertical datum is alevel surface not a horizontal surface?
because the datum surface is perpendicular tothe direction of gravity at any point on it.but the horizontal surface is perpendicular to vertical at one point on it :D
Are contour lines used to indicate horizontal distances or vertical distances on earths surface?
Horizontal
In what direction is the polarization of the glare that reflects from a horizontal surface?
It is polarized at 90 degrees to the plane of incidence. If the surface is horizontal, the plane of incidence is vertical & the polarization would be horizontal.
Why are the waves longitudinal in fluids?
because the surface of water is horizontal and not vertical.........................
What is a obliqe?
Oblique is neither vertical nor horizontal to a given line or surface
What do spirit levels tell?
It tells you if the surface it's placed against is vertical or horizontal
What is the definition of vertical distance?
The amount of separation between two horizontal surface/Plane
What do vertical and horizontal surface waves have in common?
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
What does the Hertzsprung-Russell compare?
They compare surface temperature (horizontal axis) and luminosity (vertical axis).
A line perpendicular to a surface?
Would be at at 90 degrees to the surface, in other words at right angles. So a line which was perpendicular to a horizontal surface would be vertical.
What is the different in a vertical rudder and a horizontal?
There is no horizontal rudder. The horizontal control surface is the elevator. The rudder steers, elevator makes the plane go up and down
What is the Difference between vertical hood and horizontal hood?
In the horizontal hood the air is blown across the work surface toward the operator (air flow from back to front) and in the vertical hood the air is blown down onto the work surface (air flow from top to bottom).
