Something to do with flying close to the ground at high speeds?

Yes, ground effect exists when an aircraft is very close to the ground (around half the aircraft's wingspan). This close to the ground drag is reduced and the aircraft will tend to float a little bit longer on landing (using more runway than normal) if the pilot does not account for the increased lift and reduced drag.
Ground effect can also be a factor on takeoffs as well because if a pilot tries to take off at a speed that is slightly too low, the aircraft can lift off the ground but once it climbs out of ground effect it will encounter the normal drag and settle back to the ground due to the slower speed. This can be hazardous on a short runway.

Ground effect is caused by the cushion of air formed when an aircraft is travelling at high speed close to the ground which makes it more difficult to actually make contat with the ground.
Simmilar effects happen in vehicles travelling at high speed where they start loosing traction. Spoilers on vehicles travelling at high speeds are designed to counter this.

No, it is called sound affects. Like busting children in schools is really bussing children = Rosana Danna

It could take in things like cross winds.
