Skillful predictions of tropical cyclone (TC) activity on subseasonal time scales (7–60 days) may help mitigate their destructive impacts. As the dominant component of intraseasonal (30–90 days) variability in the tropical atmosphere, the Madden–Julian oscillation (MJO) has been known to modulate TC activity. The MJO, a constantly moving atmospheric disturbance, occurs in eight phases that are defined based on which geographic region convection is detected over. In this study, a plausible mechanism was proposed through which tropical convection associated with the MJO over the eastern Pacific (phases 6–7) affects the behavior of Rossby waves (planetary-scale perturbations in the atmosphere created by Earth’s rotation which have significant influence on global weather) to thereby suppress North Atlantic TC activity. The link between these disparate phenomena, known as teleconnection, may provide useful subseasonal predictability for North Atlantic TC activity in the northern hemisphere summertime.
