he or she will probably believe the last three
fallacies on my list.
If you fly gliders at the edge of a bluff,
such as near the ocean where you have an
onshore breeze, you may notice that
sometimes the glider wants to turn away from
the bluff. Since this is upwind, it may convince
you that the first statement on my list of
fallacies is true.
As the air mass approaches the bluff, the
air is compressed and moves up and over it.
The air next to the bluff is compressed more
and is moving up faster than the air at a short
distance away. This is a form of turbulence.
When flying parallel and close to the bluff,
the inland wing is in air that is moving up
faster than the air on the other wing. This
causes a roll and resulting turn in a direction
away from the bluff. The turn is caused by
turbulence—not the horizontal movement of
the air. MA
