Technically they don't dip into ditches and even if they did the windspeed would be far less in the smaller space. They say that if you are in the open, a ditch is your best chance for survival. It would still eb pretty scary though. I don't know and have never heard anyone talk about how much of an effect the suction from the tornado would have on you in a ditch. Hopefully neither you or I will ever have to find out.
They can't exactly go in ditches because a tornado in almost any case is much wider than a ditch Ditches are actually recommended for cover if other shelter is not available. This does not guarantee survival, however.

A satellite tornado is a tornado that touches down near and usually orbits a larger tornado within the same mesocyclone.
The process of a tornado forming is called tornado genesis. Usually a tornado is a funnel cloud before it touches down.
When a tornado first reaches the ground and becomes a tornado it is said to have touched down.
Ditches are a kind of hole.
When surface winds slow down in a tornado due to ground friction, the tornado may weaken or dissipate altogether. This is because a tornado's strength is dependent on the fast rotation of air at the surface, so when this rotation slows down, the tornado's intensity is reduced.
When a tornado touches down it means it has reached the ground and can now cause damage. It is not a tornado until this occurs,
A tornado that doesn't reach all the way down is a funnel cloud. A tornado on water is a waterspout.
Air in a tornado moves up because the tornado forms in the updraft portion of a thunderstorm.
When a tornado touches down it means that it has reached the ground and can now cause damage. Prior to touching down a funnel cloud is usually visible, hanging fro the base of the thunderstorm. It does not qualify as a tornado until damaging winds reach ground level.
The dip of a unit represents the angle at which the bed inclines from the horizontal. In dip-slip faults, the fault blocks move up and down, parallel to the dip of the fault plane.
