Abstract

When a thermal is centered it might be expected that the variometer readings would be constant, and if it was not centered they would be expected to indicate a purely sinusoidal variation of climb rate with one maximum and one minimum per circle. However, it can be shown that when a glider is circled in a tilted thermal its variometer readings will include anomalous first, second and third harmonic components, even when it is centered.
