The two-way relationship between tropical cyclones over the Bay of Bengal in late fall and stationary Rossby wave propagation along the Asian jet is examined using the Japanese long-term Re-Analysis project (JRA-25) and the Japan Meteorological Agency Climate Data Assimilation System (JCDAS) data. As a precursory signal of the maximum development of the tropical cyclones migrating northward over the Bay of Bengal, a stationary wavetrain pattern prevails from the Mediterranean to the western Indian subcontinent. A cyclonic circulation anomaly to the northwest of the Bay of Bengal, which is part of the wavetrain pattern, facilitates the northward migration and enhancement of the tropical cyclones over the Bay of Bengal through the change in the mid-tropospheric mean flow and the equatorward advection of higher potential vorticity, whereas those cyclones can in turn give rise to the downstream development of the stationary Rossby wave packets along the Asian jet. Such a teleconnection further triggers surface cyclogenesis in the vicinity of Japan by leading to the intrusion of higher potential vorticity in the upper troposphere toward the Japan Sea.
