Idealized numerical simulations of tropical cyclone formation associated with monsoon gyres

Abstract

Monsoon gyres have been identified as one of the important large-scale circulation patterns associated with tropical cyclone (TC) formation in the western North Pacific. A recent observational analysis indicated that most TCs form near the center of monsoon gyres or at the northeast end of the enhanced low-level southwesterly flows on the southeast-east periphery of monsoon gyres. In the present reported study, idealized numerical experiments were conducted to examine the tropical cyclogenesis associated with Rossby wave energy dispersion with an initial idealized monsoon gyre.
