What type of adverse wind causes an airplane to bounce on a runway?

The scenario described involves an airplane bouncing on a runway, which is primarily associated with gusty winds. Gust winds are sudden changes in wind speed and direction, which can occur during the approach and landing phases of flight. When an aircraft encounters gusts, it can experience rapid fluctuations in lift and drag. These variable winds can lead to instability and turbulence as the aircraft touches down, potentially causing it to bounce instead of maintaining a smooth landing.

While crosswinds, variable winds, and headwinds can all present challenges for landing, they do not typically result in the specific bouncing effect associated with gusty conditions. Crosswinds can make it difficult to maintain the proper flight path on final approach, and headwinds can affect the landing speed. However, gusty winds are directly linked to the abrupt and often unpredictable bounces when an aircraft first contacts the runway.
