Tornadoes nearly always spin counterclockwise in the northern hemisphere and clockwise in the Southern Hemisphere with the exception of about 1% which are called anticyclonic tornadoes.
That varies. If you are close enough to be in the area of the tornado's inflow then the wind will blow almost directly towards the tornado, perhaps a little to the right of that direction. In that case the wind direction will depend on where the tornado is relative to you. If you are beyond the inflow area for the tornado, then nothing about the wind direction would indicate the approaching tornado.
The speed and direction of a tornado can be determined using Doppler radar by measuring how far the tornado moves between sweeps and in what direction.
THAT Depends on where the Storm that produced that Tornado is going
A tornado that spins in the opposite direction is known as an anticyclonic tornado. These tornadoes are rare and rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.
spine is reference direction and spline is curve, but in GSD spine is curve passing through plane.
run at an oblique angle to vertical direction of the spine.
Tornadoes change direction all the time. All that happens is the tornado goes somewhere other than where it was originally headed. It is impossible for a humans to change a tornado's direction.
No. A "sand tornado" (which is a dust devil, not an actual tornado) will move in whatever direction the wind around it is blowing.
north
The direction of a tornado can vary, but tornadoes in Missouri often come from the southwest or west due to the prevailing weather patterns in the region.
Yes. A tornado can move in any direction, though tornadoes that move westward are rare.
An individual tornado cannot change the direction that it rotates, however in rare cases a tornado may rotate in the opposite direction from what is norm (nearly all tornadoes rotate counterclockwise in the northern hemisphere, and clockwise in the southern).
