An analytical model for tropical cyclone outer-size expansion on the f-plane
Danyang Wang, Dan Chavas
Tropical cyclones are known to expand to an equilibrium size on the -plane, but the expansion process is not understood. In this study, an analytical model for tropical cyclone…

The persistence of a tropical cyclone seed vortex depends on its structure
Kuan-Yu Lu, Daniel R. Chavas, Danyang Wang
Tropical cyclones (TC) are often generated from pre-existing ``seed" vortices. Seeds with higher persistence might have a higher chance to undergo TC genesis. What controls seed pe…

Singularity as a diagnostic for secondary eyewall occurrence in tropical cyclones
Ping Lu, Long Yang, Jishi Zhang +2
Secondary eyewalls occur in 70% of major tropical cyclones (TCs), and are associated with rapid changes in storm intensity and rapid broadening of strong winds. While mechanisms of…
