Abstract Considering the atomic spatial degrees of freedom, we investigate the Bell-nonlocality dynamics of two macroscopic fields interacting with a resonant two-level atom respectively. We show that the movement of the atomic center of mass can suppress the collapse and revival of the Bell-nonlocality of the fields, and the influence is relevant with the width of the atomic wave packets. The Bell-nonlocality can disappear in a finite time for larger width of the atomic wave packets.
