Diversity of Tropical Cyclones Rapid Intensification

The study investigates the rapid intensification (RI) of tropical cyclones (TCs) in the Northwestern Pacific. We found that rapid changes in the maximum wind speed ( V max ) and the minimum central pressure ( P min ) are not always concurrent. RI cases can be categorized into three types: (a) RI v , only V max strengthens rapidly; (b) RI p , only P min decreases rapidly; (c) RI pv , rapid changes in V max and P min occur concurrently. At the onset of RI, RI v ‐type TCs exhibit the weakest intensity and the smallest size, with deep convection concentrated in the inner‐core region; RI p ‐type TCs are characterized by the strongest cyclone intensity and the largest outer‐core size, with strong convection covering the inner‐ and outer‐core regions; RI pv ‐type TCs show moderate intensity, size, and convection distribution. For RI pv , significant strengthening of wind profile is concentrated in the inner‐core region, while for RI p it is more prominent in the outer‐core.
