Abstract
Aqua planet experiments were performed to investigate any favorable environmental conditions for tropical cyclogenesis with a high-resolution atmospheric general circulation model. Zonally localized enhanced sea surface temperature distributions on the equator modify atmospheric circulation east-west asymmetrically. Tropical cyclogenesis is observed in the off-equatorial western half of the warm water pool where an enhanced distribution of absolute vorticity is produced. The region associated with the equatorward planetary vorticity transport contributes to make the western half of the pool notably favorable for generating tropical cyclones.
