What would happen if a glider encountered a strong thermal?

If a glider encounters a strong thermal, it will experience a sudden upward surge of warm air. This can provide the pilot with an opportunity to gain altitude by circling within the thermal, as the rising air can help sustain flight without engine power. However, if the thermal is too strong or turbulent, it could also pose risks, such as loss of control or excessive climb rates that may lead to structural stress on the glider. Proper techniques and awareness are crucial for safely navigating strong thermals.
