Why is it important?
We find that tropical cyclone genesis locations in the North Atlantic and eastern North Pacific vary out-of-phase. That is, a northward (southward) shift of the tropical cyclone genesis location is associated with a southward (northward) variation in the other ocean basin. It implies that hurricane outlooks can be improved by considering the two ocean basins together, and thus helping reduce the damage caused by hurricane landfall.
Perspectives
The change of cross-Central America wind in the upper troposphere, which induces an out-of-phase relation of vertical wind shear, bridges storm activity in the two ocean basins. Thus, an accurate monitoring or prediction of the upper-level zonal wind across Central America can predict TC activity in the Western Hemisphere.
