We were on Short final Runway XX at ZZZ. The ATIS was reporting WINDSHEAR ADVSRY. We were experiencing a mostly steady crosswind that was decreasing in magnitude as we made our descent. I was the Pilot Flying and upon disconnecting the autopilot at 500 ft.; I immediately started to drift above glideslope. In correcting; I over compensated; resulting in GPWS Alerts 'SINK RATE' 'GLIDE SLOPE' and 'PULL UP'. By this time we were in the runway environment; with what seemed like good corrections; slightly low on glideslope over the threshold. Thinking as I entered the crosswind flare I had made good corrections; we touched down in the Touchdown Zone safely. After landing we realized we should have executed a terrain avoidance maneuver with the Pull Up Warning.I was not prepared mentally to see that Warning in that context. I was more anticipating a Windshear Alert in that scenario and was surprised at the Pull Up Warning. I hesitated and followed through with the landing when I should have executed the terrain avoidance maneuver.
FO (First Officer) received a glideslope and Sink Rate Caution on final during a turbulent visual approach. As he was positively correcting; I saw a 'PULL UP' flash in the HGS; and then it was gone. I was waiting for the aural pull up cue; but it never came. I allowed the approach to continue because he was actively correcting the sink rate; and since there was no audio Pull Up Warning; I thought it was a momentary fluke of the system.After debriefing it; we decided on this report: Were we right in continuing; because there was no audible Pull Up Warning? We are not sure.
