Sometimes the wind will cause the thermal to bend or break,
causing a warm air bubble that slowly travels downwind as it
rises. Thermals can vary in strength, rising at speeds of a few
hundred to over a thousand feet per minute.

Thermal Form (Bubble)
As you are flying your Ascent, watch it carefully. If you were in a
full-size glider, you would be able to feel the "bump" of entering
a thermal. Now you must depend on signs the glider gives as it
approaches or enters a thermal.
When the Ascent flies near a thermal that is rising, the wing
closest to the thermal will also try to rise, causing the aircraft to
"rock" slightly. The nearness of a thermal will cause the glider to
"turn away" without any control input from the pilot.
Executing a 270-degree turn
There are several ways of entering a thermal. One is to continue
the thermal-induced turn for 270 degrees. If the thermal is on
your right, turn left for 270 degrees and enter at a right angle to
the original flight path.
