Types of tropical cyclogenesis in the South China Sea

What is it about?

The different types of precursor synoptic disturbances associated with tropical cyclone genesis in the South China Sea (SCS) are identified. The mesoscale convective activity, atmospheric quasi-biweekly oscillation, Madden-Julian oscillation and sea surface temperature associated with the tropical cyclogenesis in the SCS are analyzed.

Why is it important?

The synoptic-scale perturbations associated with tropical cyclone (TC) genesis in the South China Sea (SCS) are examined for the first time by separating the synoptic-scale component. New type of precursor synoptic-scale perturbation associated with TC genesis in the SCS is found.
