The TC size at any time can be significantly impacted by a region with a different SST (see Figure 4), and these SST-induced size changes are not quickly restored when the cyclone has crossed the anomaly. The size and integrated kinetic energy can be considered as path dependent as they are a consequence of the integrated ocean …
