Flight Crew Landed As Precaution
Aircraft; Human Factors; Weather
Approaching to land in Atlanta on Runway 27; there was a thunderstorm north of the airport. Approximately 15 seconds prior to touchdown we received a 'monitor radar display' aural alert. The Crew elected to continue the landing. The wind was a constant 20 knots through the final and landing sequence. The Tower did not issue any windshear warnings and no aircraft in front or behind our aircraft executed a go-around. After aircraft shutdown at the gate; we reviewed the QRH; which confirmed our suspicion that we; indeed; should have gone around.A more thorough review of items in the QRH such as this could be accomplished. During the landing flare; I was ready to execute the go-around once I received the 'monitor radar display;' however; I was erroneously waiting for the 'windshear ahead; go-around' warning from the automated system. This type of alert can trap a lot of Crews since we are often spring loaded to act only after receiving aural warnings and not aural 'cautions.' Since this happened just before beginning the landing flare; there wasn't a lot of time for discussion during the event.
Upon receiving a 'monitor radar display' aural warning while initiating the flare for landing (during atmospheric conditions consistent with potential predictive windshear alerts) the Captain of a B737-700 opted to complete the landing rather than initiate a go-around.
