Glider pilots depend largely on finding columns of
rising air known as thermals to keep their aircraft
flying. Understanding what the weather conditions
are and what they will do is fundamental to successful
also use ridge lift to slope soar, sailing along
on the updraft from a strong wind against a ridge
or mountain side.
we are fortunate to find a phenomenon called wave
where a wind with steady direction and increasing
speed with height flows over obstructions such
as a mountain, creating waves in the air like water.
These waves, on the upside, can go to 30,000 feet
or even higher. The downside can come down very
quickly indeed and cause what power pilots refer
to as microbursts.
