Tropical Cyclone Intensification and Fullness: The Role of Storm Size Configuration

The relationships between the intensification rate (IR) and size configuration of tropical cyclones (TCs) are investigated. Theoretically, intensity, configuration, relative vorticity TCs intrinsically linked. TC fullness (TCF) is used to quantify can be expressed as product critical (TCF0) ratio (Rf). TCF0 represents fundamental constraint on shared by at a given intensity lower limit fullness, whereas Rf reveals TC's unique wind structural feature. Intermediate (∼0.55), moderate (∼1.4), thus high TCF (∼0.8) collectively facilitate occurrence large IR TC. Obtaining stable low favors subsequent TCF-TCF0 diagram proposed illustrate co-evolution reveal how they modulate intensification.
